LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Core  Bond  Portfolio,  covering  the  period  from the portfolio's
inception  on  May  1,  2000 through June 30, 2000. Inside, you'll find valuable
information  about  how  the  portfolio was managed during the reporting period,
including  a discussion with Michael Hoeh, portfolio manager and a member of the
Dreyfus Taxable Fixed Income Team that manages the portfolio.

Tighter monetary policy adversely affected most -- but not all -- sectors of the
bond  market over the past six months. This was primarily a result of efforts by
the  Federal  Reserve  Board  (the  "Fed" ) to  forestall potential inflationary
pressures.  The  Fed  raised  short-term interest rates by .50 percentage points
since  the  portfolio' s  inception. This increase in May contributed to a total
interest-rate  increase  of  1.75  percentage  points  since  late  June  1999.

Higher  interest  rates  led to an erosion of most bond prices, especially among
higher  yielding  securities.  U.S.  Treasury  securities  represented a notable
exception.  Prices  of  these  direct obligations of the federal government rose
primarily because of reduced supply amid robust demand from domestic and foreign
investors.

We   appreciate   your   confidence  and  we  look  forward  to  your  continued
participation in Dreyfus Investment Portfolios, Core Bond Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Michael Hoeh, Portfolio Manager Dreyfus Taxable Fixed Income Team

How did Dreyfus Investment Portfolios, Core Bond Portfolio perform during the
period?

For  the  period  from the portfolio's inception on May 1, 2000 through June 30,
2000, the portfolio produced a total return of 1.68%.(1)

We  attribute  the portfolio's performance to our efforts to begin deploying the
portfolio' s  assets  into  various areas of the bond market. Over the two-month
reporting  period,  we  gradually  invested  the portfolio's assets into various
sectors of the bond market.

What is the portfolio's investment approach?

The  portfolio  seeks to maximize total return through both capital appreciation
and  current  income.  The  portfolio  invests  at  least  65%  of its assets in
investment   grade   fixed-income   securities,   which  include  U.S.  Treasury
securities,  U.S.  Government agency securities, corporate bonds, foreign bonds,
mortgage-  and  asset-backed  securities,  convertible  securities and preferred
stocks.  The  portfolio  may invest up to 35% of its assets in bonds rated below
investment grade credit quality, also known as "high yield" securities.

Our investment approach emphasizes:

*FUNDAMENTAL  ECONOMIC  ANALYSIS. Our review of U.S. economic conditions helps
us establish the portfolio's average duration, which is a measure of sensitivity
to  interest-rate  changes.  If  interest  rates  appear  to  be rising, we will
generally reduce the portfolio's average duration to keep cash available for the
purchase  of  higher  yielding  securities as they become available. If interest
rates appear to be declining, we will generally increase the portfolio's average
duration to lock in prevailing yields.

                                                                  The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

*SECTOR  ALLOCATION.  We  allocate  assets  among  the  various sectors of the
fixed-income  marketplace  according  to  their relative attractiveness based on
prevailing and expected market and economic conditions.

*SECURITY SELECTION. We choose individual securities according to factors that
include their yields, prices, liquidity and the financial health of the issuers.

What other factors influenced the portfolio's performance?

During  the  two  months  since  its  inception,  the  portfolio  was  primarily
influenced  by  inflation fears, rising interest rates and unusual conditions in
the  U.S.  Treasury  securities  marketplace. Investors have been concerned that
robust  economic  growth  might  rekindle  long-dormant  inflationary pressures,
especially  rising  wages  in a tight job market. In an attempt to relieve these
pressures,  the Federal Reserve Board (the "Fed") has raised short-term interest
rates  six  times since June 1999, including once in May 2000, causing most bond
prices to fall.

The  portfolio  was  also  affected by forces that are unique to individual bond
market  sectors.  For  example,  U.S.  Treasury  securities during the reporting
period  provided  attractive  returns  compared  to other market sectors. That's
because  the federal budget surplus has reduced the government's need to borrow,
and the U.S. Treasury Department announced its intention to use a portion of the
budget  surplus  to  buy  back  higher yielding, long-term bonds. With a reduced
supply  of  U.S. Treasury securities and strong demand from domestic and foreign
investors, prices of these securities rose sharply.

What is the portfolio's current strategy?

We  are  continuing our efforts to invest the portfolio's assets in areas of the
bond  market  that  we  believe  offer  attractive opportunities. Our management
strategy  was  designed to help us balance the benefits of locking in prevailing
yields while maintaining the flexibility to capture higher yields as they become
available.


As  of  June  30,  2000,  the  portfolio was primarily invested in U.S. Treasury
securities  and  U.S.  Government  agency  securities.  We have also established
smaller  positions  in  corporate  bonds  and  asset-backed  securities.  It  is
currently  our  intention  to  gradually build on our asset-backed and corporate
bond  holdings,  including  a  modest  position  in  high yield corporate bonds.
Although  we  may invest in bonds of foreign governments and corporations in the
future, we have not yet established a position in this area.

Approximately  61%  of the portfolio's net assets are currently invested in U.S.
Government  agency  securities -- primarily mortgage-backed securities issued by
Federal  National Home Mortgage Association ("Fannie Mae") and Federal Home Loan
Corporation  ("Freddie Mac"). We  believe that these securities are currently
undervalued  because  of political pressures. Although some government officials
have  questioned  the agencies' investment policies, we believe that any changes
are  unlikely  and  U.S. Government agency securities' prices can rebound as the
situation is resolved.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company,  operating  as  a  series company currently offering twelve
series,  including  the  Core  Bond Portfolio (the "portfolio"), which commenced
operations  on  May  1, 2000. The portfolio is only offered to separate accounts
established  by  insurance  companies  to  fund  variable  annuity contracts and
variable  life  insurance  policies.  The portfolio is a diversified series. The
portfolio's  investment  objective  is to maximize total return through capital
appreciation  and  current income. The Dreyfus Corporation ("Dreyfus") serves as
the  portfolio's  investment  adviser. Dreyfus is a direct subsidiary of Mellon
Bank,  N.A.  ("Mellon"), which is a wholly-owned subsidiary of Mellon Financial
Corporation.  Dreyfus  Service Corporation ("DSC"), a wholly-owned subsidiary of
Dreyfus  is  the  distributor  of  the portfolio's shares, which are sold to the
public without a sales charge.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 401,900 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)   PORTFOLIO  VALUATION:  Investments  in  securities  (excluding  short-term
investments,  other  than U.S. Treasury Bills, and financial futures) are valued
each  business day by an independent pricing service ("Service") approved by the
Board of Trustees. Investments for which quoted bid prices are readily available
and  are  representative  of  the  bid side of the market in the judgment of the
Service are valued at the
                                                                  The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

mean  between  the quoted bid prices (as obtained by the Service from dealers in
such  securities)  and asked prices (as calculated by the Service based upon its
evaluation  of  the  market  for  such  securities) . Other  investments  (which
constitute  a majority of the portfolio securities) are carried at fair value as
determined  by  the  Service,  based  on methods which include consideration of:
yields or prices of securities of comparable quality, coupon, maturity and type;
indications as to values from dealers; and general market conditions. Securities
for which there are no such valuations are valued at fair value as determined in
good faith under the direction of the Board of Trustees. Short-term investments,
excluding U.S. Treasury Bills, are carried at amortized cost, which approximates
value.  Financial  futures  are valued at the last sales price on the securities
exchange  on  which  such  securities  are primarily traded or at the last sales
price on the national securities market on each business day.

(B)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio receives
net earnings credits based on available cash balances left on deposit.

(C)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net are declared and paid monthly. Dividends
from net realized capital gain, if any, are normally declared and paid annually,
but the portfolio may make distributions on a more frequent basis to comply with
the  distribution  requirements of the Internal Revenue Code of 1986, as amended
(the  "Code" ). To  the  extent  that net realized capital gain can be offset by
capital  loss  carryovers,  if  any,  it  is  the policy of the portfolio not to
distribute such gain.

On  June  30,  2000, the Board of Trustees declared a cash dividend of $.063 per
share  from  undistributed  investment  income-net,  payable  on  July  3,  2000
(ex-dividend date) to shareholders of record as of the close of business on June
30, 2000.

(D)  FEDERAL  INCOME  TAXES:  It  is the policy of the portfolio to qualify as a
regulated  investment company, if such qualification is in the best interests of
its  shareholders,  by complying with the applicable provisions of the Code, and
to   make  distributions  of  taxable  income  sufficient  to  relieve  it  from
substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee and Other Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .60 of 1% of the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  May  1,  2000 through April 30, 2001, to reduce the investment
advisory  fee  and  reimburse such excess expenses paid by the portfolio, to the
extent  that  the  portfolio's  aggregate  annual expenses, exclusive of taxes,

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Core Value Portfolio, covering the six-month period from January 1,
2000  through  June 30, 2000. Inside, you'll find valuable information about how
the  portfolio  was  managed during the reporting period, including a discussion
with the portfolio manager, Valerie J. Sill.

While  stock prices were little changed on average over the past six months, the
period  was  marked by high levels of volatility and dramatic shifts in investor
sentiment.  Between  January and mid-March, large-cap stocks generally continued
to advance, led by fast-growing technology stocks that, many investors believed,
would  benefit  most  from  the "new economy." Subsequently, however, technology
stocks corrected sharply over concerns about rising interest rates and extremely
high  valuations.  Other  sectors  of  the large-cap stock market also declined,
erasing the gains achieved earlier in the year.

Also,  primarily  because  of  the  precipitous drop in technology stock prices,
value-oriented  stocks generally outperformed growth stocks during the reporting
period,  a  reversal  of  the  trend established over the past several years. In
addition,  small-capitalization  stocks generally outperformed large-cap stocks,
particularly  in  the  value-oriented  segment of the market. In our view, these
short-term  swings  in investor sentiment highlight once again the importance of
broad diversification and a long-term perspective for most investors.

We  appreciate  your confidence over the past six months, and we look forward to
your  continued  participation  in  Dreyfus  Investment  Portfolios,  Core Value
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Valerie J. Sill, Portfolio Manager

How did Dreyfus Investment Portfolios, Core Value Portfolio perform relative to
its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Core  Value  Portfolio  produced a total return of -0.39%.(1) In comparison, the
portfolio's  benchmark,  the Standard & Poor's 500/BARRA Value Index produced a
total return of -4.07% for the same period.(2)

During  the  first  two  months  of 2000, investors preferred high-flying growth
stocks  such as Internet companies over more conservative businesses that posted
solid  profits.  However, by early March, economic and inflation data heightened
investor concerns about the high prices that they were paying for growth stocks.
As  a result, a shift back to the fundamentals of stock analysis took place and,
in  turn,  a  shift to the more reasonably priced value stocks. By late May, the
efforts  made  by  the  Federal  Reserve  Board  to  slow  the economy and fight
inflation   appeared   successful  and  growth  stocks  became  popular  again.

What is the portfolio's investment approach?

The  portfolio  invests  primarily  in companies that are considered undervalued
based  on  traditional  measures  such  as price-to-earnings ratios. In choosing
stocks,  we  use a bottom-up stock selection approach that focuses on individual
companies, rather than a top-down approach that forecasts market trends. We also
focus  on  a  company' s  relative value, financial strength, sales and earnings
momentum and likely catalysts that could ignite the stock price.

What other factors influenced the portfolio's performance?

One  positive  factor  in the portfolio's performance was its strong emphasis on
the  pharmaceutical  sector,  one of the best performing stock groups during the
period. Historically, pharmaceuticals were con-
                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

sidered  a  growth  category  because  the  companies  produced higher growth in
earnings  than  the  stock  market  as a whole and investors were willing to pay
premium  prices  for  that.  However,  in  the  past year, pharmaceutical stocks
behaved  more  like a value sector, coming down in price for two reasons. First,
growth  investors  appeared  to be fixated on the growth potential of technology
stocks  which  were  perceived to be higher than the growth potential offered by
pharmaceutical  companies. And second, the United States Congress began debating
the  merits  of  expanding Medicare to cover prescription drugs. That debate was
viewed  as  a threat to the companies' profits because Medicare reimbursement to
hospitals had already adversely impacted that industry.

In  addition,  concerns at individual companies further depressed pharmaceutical
stock  prices.  For  example,  Abbott Laboratories, a company that was forced by
federal  regulators  to  recall  a number of diagnostic tests on the market, had
their  stock price fall sharply as a result of the recall. The stock of American
Home  Products  was hurt because of litigation over one of its diet products and
the  perceived  cost  of  settlement.  We  viewed  these  developments as buying
opportunities,  and  the  stocks  have since appreciated in value. By the second
quarter  of  2000,  pharmaceutical  companies  continued to post strong earnings
while technology stocks faltered.

Another   positive   factor  affecting  performance  was  our  ability  to  spot
"miscellaneous" underpriced stocks in a variety of industries. For instance, in
media  and  entertainment, Disney (Walt), which owns the ABC television network,
began  producing  extremely  strong  profits  during  the  portfolio's reporting
period,  largely  due  to  the  success  of  the "Who Wants To Be A Millionaire"
program.  In  the  brokerage industry, both Morgan Stanley Dean Witter & Co. and
Citigroup  benefited  from  unusually  high  stock market volatility and trading
volumes  during  the  first half of 2000. In technology, the portfolio benefited
from  Netherlands-based  Koninklijke  (Royal)  Philips  Electronics'  success in
satisfying the booming global demand for semiconductors, the building blocks for
computers and other electronic devices.


However, the portfolio's performance was hampered by its holdings in the banking
industry,  which  continued  to  perform  poorly due to the rising interest-rate
environment.  In addition, economically cyclical companies, such as those in the
chemicals  and  paper  industries, began the year strong but performed poorly in
the second quarter as the U.S. economy began to slow down.

What is the portfolio's current strategy?

Regardless  of  whether  growth  or  value style of investing is in favor at the
moment,   our  strategy  remains  consistent.  We  will  continue  to  look  for
undervalued  stocks  that,  in our opinion, have the potential to provide strong
stock  price  performance  regardless of their industry. In addition, we believe
the  portfolio  should  benefit  from  the  renewed respect among the investment
community  for  companies  that post strong profits. Even with the resurgence in
stock  prices  toward the end of June, we believe that there is a wide selection
of attractively priced companies available to us.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company,  operating  as  a  series company currently offering twelve
series,  including  the Core Value Portfolio (the "portfolio"). The portfolio is
only  offered  to  separate  accounts established by insurance companies to fund
variable  annuity  contracts and variable life insurance policies. The portfolio
is  a  diversified  series.  The  portfolio's investment objective is to provide
long-term  capital  growth.  The  Dreyfus  Corporation ("Dreyfus") serves as the
portfolio's  investment adviser. Dreyfus is a direct subsidiary of Mellon Bank,
N.A.,  ("Mellon") which  is  a  wholly-owned  subsidiary  of  Mellon Financial
Corporation.  Effective  March  22, 2000, Dreyfus Service Corporation ("DSC"), a
wholly-owned  subsidiary  of  Dreyfus  became the distributor of the portfolio's
shares,  which are sold to the public without a sales charge. Prior to March 22,
2000, Premier Mutual Fund Services, Inc. was the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 406,195 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(a)  Portfolio  valuation:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities market, or securities for which
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

there were no transactions, are valued at the average of the most recent bid and
asked prices. Bid price is used when no asked price is available. Securities for
which  there  are  no  such valuations are valued at fair value as determined in
good faith under the direction of the Board of Trustees. Investments denominated
in  foreign currencies are translated to U.S. dollars at the prevailing rates of
exchange. Forward currency exchange contracts are valued at the forward rate.

(b)  Foreign  currency transactions: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(c)  Securities  transactions and investment income: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits  of  $359  during the period ended June 30, 2000 based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.


(d)  Dividends  to shareholders: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(e)  Federal  income  taxes:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2-Bank Line of Credit:

The  portfolio  participates  with other Dreyfus-managed funds in a $100 million
unsecured  line  of  credit  primarily to be utilized for temporary or emergency
purposes,  including  the  financing  of redemptions. Interest is charged to the
portfolio  at rates which are related to the Federal Funds rate in effect at the
time of borrowings. During the period ended June 30, 2000, the portfolio did not
borrow under the line of credit.

NOTE 3--Investment Advisory Fee and Other Transactions With Affiliates:

(a)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .75 of 1% of the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio' s  aggregate annual expenses,
exclusive of taxes, brokerage
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

fees,  interest  on borrowings and extraordinary expenses, exceed an annual rate
of 1% of the value of the portfolio's average daily net assets. The reduction in
investment advisory fee, pursuant to the undertaking, amounted to $13,120 during
the period ended June 30, 2000.

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was charged $44 pursuant to the
transfer agency agreement.

The  portfolio  compensates  Mellon  under  a  custody  agreement  for providing
custodial services for the portfolio. During the period ended June 30, 2000, the
portfolio was charged $5,787 pursuant to the custody agreement.

(b)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.


NOTE 4--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$11,911,250 and $7,897,948, respectively.

At  June  30,  2000,  accumulated net unrealized appreciation on investments was

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  MidCap  Stock Portfolio, covering the six-month period from January
1,  2000  through  June 30, 2000. Inside, you'll find valuable information about
how  the  portfolio  was  managed  during  the  reporting  period,  including  a
discussion with the portfolio manager, John O'Toole.

While  midcap  stock  prices  were,  as  measured  by  the Russell Midcap Index,
modestly  higher  over the past six months, the period was marked by high levels
of  volatility  and  dramatic  shifts in investor sentiment. Between January and
mid-March,   stocks  of  all  sizes  generally  continued  to  advance,  led  by
fast-growing technology stocks that, many investors believed, would benefit most
from  the  "new  economy."  Subsequently,  however,  technology stocks corrected
sharply over concerns about rising interest rates and extremely high valuations.
Other  sectors  of  the  stock  market  also declined, erasing most of the gains
achieved earlier in the year.

Overall,   mid-capitalization   stocks   generally  outperformed  large-cap  and
small-cap  stocks during the period, particularly in the growth-oriented segment
of  the  market,  which is dominated by technology companies. In our view, these
short-term  swings  in investor sentiment highlight once again the importance of
broad diversification and a long-term perspective for most investors.

We  appreciate  your confidence over the past six months, and we look forward to
your  continued  participation  in  Dreyfus  Investment Portfolios, MidCap Stock
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

DISCUSSION OF PERFORMANCE

John O'Toole, Portfolio Manager

How did Dreyfus Investment Portfolios, MidCap Stock Portfolio perform relative
to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
MidCap  Stock  Portfolio  produced  a total return of 6.63%.(1 )In contrast, the
Standard & Poor's MidCap 400 Index (the "S&P MidCap 400 Index"), the portfolio's
benchmark, produced a total return of 9.06% for the same period.(2)

Much  of the portfolio's underperformance of the S&P MidCap 400 Index during the
reporting  period  is attributable to growth stocks overwhelmingly outperforming
value  stocks  in  the  first quarter of 2000. Our quantitative model examines a
mixture  of  growth and value characteristics, without strongly favoring either.
The  model  does not work as well in a polarized market environment, such as the
one  that  prevailed  in  the  first quarter of 2000, where one investment style
dominates another.

What is the portfolio's investment approach?

The portfolio invests primarily in mid-capitalization companies chosen through a
disciplined  process  that  combines  computer analysis with human judgment. The
quantitatively driven valuation process identifies and ranks approximately 2,500
midcap  stocks as attractive, neutral or unattractive investments, based on more
than a dozen different valuation inputs. Those inputs, which we believe can have
an  important  influence  on  stock  returns, include earnings estimates, profit
margins  and growth in cash flow. We establish weights for each of these factors
based  on  our analysis of which factors are being rewarded by investors, making
adjustments  along the way for the uniqueness of various industries and economic
sectors.  For example, the equity markets may be rewarding companies with strong
growth  in  cash  flow,  in  which case we would add more weight to that factor.

                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

Then,  our  investment  management  team  conducts  fundamental research on each
stock,  which  ultimately results in their buy-and-sell recommendations. We seek
to have the portfolio own the best-performing midcap stocks within each economic
sector.

What other factors influenced the portfolio's performance?

During  the  past six months, midcap stocks were among the best-performing stock
groups in the equity universe.  That's a marked change from the late 1990s, when
investors  flocked  to  large-cap  companies  because  they  posted  such strong
earnings  growth. More recently, midcap companies have become attractive because
of  their  often  strong  growth  prospects  and  their  relatively modest stock
valuations.  Indeed,  the  strong  performance  of  midcap stocks was a positive
factor in the portfolio's results.

Biotechnology  was  one  of  the  top-performing midcap areas during the period.
Recently,  the federal government and private industry scientists announced that
they  had deciphered the genetic code for human life. Among other benefits, this
scientific discovery may make it possible for biotechnology companies to develop
more  effective  drugs  to  treat  diseases.  As  a  result,  the stock price of
portfolio  holding  Waters more than doubled during the reporting period. Waters
is  a  provider  of  laboratory  products  and  services  to the pharmaceutical,
chemical and environmental testing industries.

Although  technology  experienced  tremendous  volatility  during  the reporting
period, investors expressed a clear preference for companies with solid earnings
and shunned Internet companies that had losses and questionable business models.
Sanmina,  a  very  profitable  manufacturer  of  electronic components for major
computer  corporations,  was  an  example  of one of the portfolio's holdings in
technology that was preferred by investors.

As the world's telecommunication system makes the transition from copper to more
advanced  technologies,  companies  like  CIENA  Corp.  are  developing the next
generation  of  fiber  optic  networks.  The  booming growth of the Internet has
enabled many of these telecommunications companies to generate tremendous
growth, which is why CIENA's stock price nearly doubled during the reporting
period.

Another  group of companies in the portfolio performed very well, not because of
the  good  fortunes  of  their respective industries, but because the individual
companies met or exceeded profit expectations. Those stocks included Dollar Tree
Stores,  an  operator of discount variety stores, Santa Fe International, an oil
drilling  company that took advantage of rising oil prices, and Quanta Services,
a  construction  company  that  specializes  in  the  telecommunications,  cable
television  and  electric power industries. In contrast, a large majority of the
stocks  that  did  not  perform  well  were  those  of  companies  that produced
disappointing earnings, such as BJ's Wholesale Club, Dial and USFreightways.

What is the portfolio's current strategy?

We  continue  to  follow  our  quantitatively  driven  computer  model  and  use
fundamental  analysis for selecting stocks. We also continue to believe that the
midcap  sector  of  the  market  represents  a  collection  of  very dynamic and
interesting  companies  whose  stock valuations are still often lower than their
large-cap counterparts.

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company,  operating  as  a  series company currently offering twelve
series, including the MidCap Stock Portfolio (the "portfolio"). The portfolio is
only  offered  to  separate  accounts established by insurance companies to fund
variable  annuity  contracts and variable life insurance policies. The portfolio
is  a  diversified  series.  The  portfolio's investment objective is to provide
investment  results  that  are  greater  than  the  total  return performance of
publicly-traded   common   stocks  of  medium-size  domestic  companies  in  the
aggregate, as represented by the Standard & Poor's MidCap 400 Index. The Dreyfus
Corporation ("Dreyfus") serves as the portfolio's investment adviser. Dreyfus is
a  direct  subsidiary  of  Mellon Bank, N.A., ("Mellon") which is a wholly-owned
subsidiary  of  Mellon  Financial Corporation. Effective March 22, 2000, Dreyfus
Service  Corporation  ("DSC"), a wholly-owned subsidiary of Dreyfus, became the
distributor  of  the  portfolio's shares, which are sold to the public without a
sales  charge.  Prior  to March 22, 2000, Premier Mutual Fund Services, Inc. was
the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 309,506 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securi

ties exchange on which such securities are primarily traded or at the last sales
price on the national securities market. Securities not listed on an exchange or
the   national  securities  market,  or  securities  for  which  there  were  no
transactions, are valued at the average of the most recent bid and asked prices.
Bid  price  is used when no asked price is available. Securities for which there
are  no  such  valuations  are  valued at fair value as determined in good faith
under the direction of the Board of Trustees.

(B)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits  of  $984  during the period ended June 30, 2000 based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.

The  portfolio may enter into repurchase agreements with financial institutions,
deemed  to be creditworthy by the portfolio's investment adviser, subject to the
seller's  agreement  to repurchase and the portfolio's agreement to resell such
securities  at  a  mutually  agreed  upon price. Securities purchased subject to
repurchase agreements are deposited with the portfolio's custodian and, pursuant
to  the  terms  of the repurchase agreement, must have an aggregate market value
greater than or equal to the terms of the repurchase price plus accrued interest
at all times. If the value of the underlying securities falls below the value of
the  repurchase  price  plus  accrued  interest,  the portfolio will require the
seller to deposit additional collateral by the next business day. If the request
for  additional  collateral is not met, or the seller defaults on its repurchase
obligation,  the portfolio maintains its right to sell the underlying securities
at market value and may claim any resulting loss against the seller.

                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

(C)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers, it is the policy of the portfolio not to distribute such gain.

(D)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

The  portfolio  has  an  unused capital loss carryover of approximately $188,000
available  for  Federal  income  tax  purposes  to be applied against future net
securities  profits,  if  any,  realized subsequent to December 31, 1999. If not
applied, the carryover expires in fiscal 2006.

NOTE 2--Bank Line of Credit:

The  portfolio  participates  with other Dreyfus-managed funds in a $100 million
unsecured  line  of  credit  primarily to be utilized for temporary or emergency
purposes,  including  the  financing  of redemptions. Interest is charged to the
portfolio  at rates which are related to the Federal Funds rate in effect at the
time of borrowings. During the period ended June 30, 2000, the portfolio did not
borrow under the line of credit.

NOTE 3--Investment Advisory Fee and Other Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .75 of 1% of the value of the
portfolio's average daily net assets and is payable monthly.  Dreyfus has
undertaken from January 1, 2000 through December 31, 2000, to reduce the
investment advisory fee and reimburse such excess expenses paid by the
portfolio, to the extent that the portfolio's aggregate annual expenses,
exclusive of taxes, brokerage fees, interest on borrowings and extraordinary
expenses, exceed an annual rate of 1% of the value of the portfolio's average
daily net assets. The reduction in investment advisory fee, pursuant to the
undertaking, amounted to $16,368 during the period ended June 30, 2000.

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was charged $38 pursuant to the
transfer agency agreement.

The  portfolio  compensates  Mellon  under  a  custody  agreement  for providing
custodial services for the portfolio. During the period ended June 30, 2000, the
portfolio was charged $16,157 pursuant to the custody agreement.

(B)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.

                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

NOTE 4--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$25,939,471 and $11,361,689, respectively.

At  June  30,  2000,  accumulated net unrealized appreciation on investments was
$1,196,697,   consisting   of   $3,538,199  gross  unrealized  appreciation  and
$2,341,502 gross unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Technology  Growth  Portfolio,  covering  the six-month period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  portfolio  was managed during the reporting period, including a
discussion with the portfolio manager, Mark Herskovitz.

During  most  of the first quarter of 2000, technology stocks continued to rally
on  the  strength  of  investor  enthusiasm for the "new economy." In mid-March,
however,  investor  sentiment changed dramatically amid fears of higher interest
rates.  As  a result, many technology stocks subsequently fell out of favor, and
many  investors  shifted  their  attention  to  other market sectors. Within the
technology  sector, stocks of young, relatively untested Internet companies were
hardest  hit,  while  well-established,  profitable  companies  engaged  in  the
build-out  of  data,  video  and  voice  telecommunications  infrastructure were
generally the most resilient.

We  appreciate  your confidence over the past six months, and we look forward to
your continued participation in Dreyfus Investment Portfolios, Technology Growth
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Mark Herskovitz, Primary Portfolio Manager

How did Dreyfus Investment Portfolios, Technology Growth Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Technology Growth Portfolio produced a total return of 13.10%.(1) In comparison,
the Morgan Stanley High Technology 35 Index produced a total return of 10.42%(2)
and  the  Standard  & Poor' s  500 Composite Stock Price Index ("S&P 500 Index")
produced a total return of -0.43% (3) for the same period.

The portfolio's performance was affected by a dramatic shift in market sentiment
away  from technology-related stocks, which had reached lofty valuations after a
spectacular  1999,  and into formerly out-of-favor industrial and value-oriented
stocks  beginning  in mid-March. We hasten to add that the correction within the
volatile technology sector was not unexpected, and we continue to urge investors
to  maintain  a  long-term  perspective  and  a diversified investment approach.

What is the portfolio's investment approach?

The  portfolio  seeks  capital  appreciation  by  investing  primarily in growth
companies  of any size that we believe are leading producers or beneficiaries of
technological  innovation.  These  investments  may  include  companies  in  the
computer,    semiconductor,    electronics,   communications,   health   care,
biotechnology,   computer  software  and  hardware,  electronic  components  and
systems,  networking  and  cable  broadcasting,  telecommunications, defense and
aerospace, and environmental sectors.

When  evaluating  investment  opportunities, we first assess economic and market
conditions  in an attempt to identify trends that we believe are likely to drive
demand  within  the  various  technology-related  sectors.  Second, we strive to
identify  the  companies  that  are  most  likely  to benefit from these overall
trends. Typically, these companies are leaders in their market segments, and are
characterized  by  rapid  earnings growth and dominant market shares. We conduct
extensive  fundamental  research  to  understand  these  companies'  competitive
advantages and to
                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

evaluate their ability to maintain their leadership positions over time.

This  process  enables  us  to  select  leading  technology  companies  for  the
portfolio.  Many  of  those  stocks are considered core holdings that we believe
will  lead  their  industry  segments  over  the  long term. We complement these
positions  with  non-core  holdings  that  we believe will provide above-average
gains over a shorter time frame.

Although  the  portfolio  looks  for  companies  with  the  potential for strong
earnings  growth  rates,  some  of  the portfolio's investments may currently be
experiencing  losses.  Moreover,  the  portfolio  may invest in small-, mid- and
large-cap  securities in all available trading markets, including initial public
offerings  (IPOs)  and the aftermarket. The portfolio's strategy with respect to
IPOs  is  relatively  conservative,  in  that  management  has  chosen  only  to
participate  in  IPOs of companies that meet the portfolio's investment criteria
described  above and that we believe have the potential to become full positions
within the portfolio.

What other factors influenced the portfolio's performance?

The  portfolio's  performance  was  adversely influenced by a dramatic shift in
market sentiment that began in mid-March. Before this change, the stock market's
advance  continued  to  be  driven  by technology stocks that investors believed
would  be most likely to succeed in the "new economy." While we believe that the
strong  business  fundamentals  of  these businesses have not changed -- indeed,
they  may  have improved, in our opinion -- technology stocks had appreciated to
very  high  prices  relative  to  their  earnings,  book  values and other value
measures.

Investors  became  concerned  that  the  Federal Reserve Board's efforts to slow
economic  growth might cause demand for new technologies to slacken. While there
has  been little evidence of a slowdown in demand, a major measure of technology
stock  performance,  the  Nasdaq  Composite  Index,  fell  substantially between
mid-March and the end of April, including a notable single-day drop on April 14

On  the other hand, the portfolio's performance was positively influenced by our
stock  selection and diversification strategies. We continued to focus primarily
on  companies  that  our research indicated were fundamentally sound and in good
positions to prosper from techno-

logical advances. During the six-month period, these included telecommunications
equipment  suppliers, computer storage manufacturers, data network providers and
contract   manufacturers.   We   also   placed   greater   emphasis  on  large,
well-established  technology leaders such as Texas Instruments, Oracle and Cisco
Systems.  On  the  other  hand,  we tended to avoid some of the more speculative
industry  groups,  including  so-called  "pure  play"  Internet companies facing
intense competition and uncertain revenue streams.

What is the portfolio's current strategy?

We have continued to conduct extensive research to identify technology companies
that  have strong or improving business fundamentals and rising demand for their
products and services. Accordingly, we have recently begun to focus on companies
that we believe will benefit from advances in technologies for wireless Internet
access.

Despite  the  recent contraction of valuations, we again caution that technology
stocks  are  likely  to  continue  to  experience high levels of volatility, and
investors  should  not be surprised to see periodic and significant advances and
declines.  As  always,  our  risk  management  strategy is to maintain a broadly
diversified technology portfolio and to focus on fundamentally sound companies.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act"), as  an  open-end management
investment  company  operating  as  a  series  company currently offering twelve
series,  including  the  Technology  Growth  Portfolio  (the  "portfolio"). The
portfolio  is  only  offered  to  separate  accounts  established  by  insurance
companies  to  fund  variable  annuity  contracts  and  variable  life insurance
policies.  The  portfolio  is  a  diversified series. The portfolio's investment
objective  is  to  provide  long-term  capital  growth.  The Dreyfus Corporation
("Dreyfus") serves  as the portfolio's investment adviser. Dreyfus is a direct
subsidiary  of  Mellon Bank, N.A. ("Mellon"), which is a wholly-owned subsidiary
of  Mellon  Financial  Corporation.  Effective  March  22, 2000, Dreyfus Service
Corporation   ("DSC" ), a  wholly-owned  subsidiary  of  Dreyfus,  became  the
distributor  of  the  portfolio's shares, which are sold to the public without a
sales  charge.  Prior  to March 22, 2000, Premier Mutual Fund Services, Inc. was
the distributor.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(a)  Portfolio  valuation:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities  market,  or  securities  for  which  there were no transactions, are
valued  at  the average of the most recent bid and asked prices, except for open
short positions, where the asked price is used for valuation purposes. Bid price
is used when no asked
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

price is available. Securities for which there are no such valuations are valued
at  fair  value  as determined in good faith under the direction of the Board of
Trustees.  Investments  denominated in foreign currencies are translated to U.S.
dollars at the prevailing rates of exchange. Forward currency exchange contracts
are valued at the forward rate.

(b)  Foreign  currency transactions: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(c)  Securities  transactions and investment income: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits of $2,234 during the period ended June 30, 2000, based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.


(d)  Dividends  to shareholders: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(e)  Federal  income  taxes:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee and Other Transactions With Affiliates:

(a)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .75 of 1% of the value of the
portfolio's average daily net assets and is payable monthly.

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was charged $38 pursuant to the
transfer agency agreement.

The  portfolio  compensates  Mellon  under  a  custody  agreement  for providing
custodial services for the portfolio. During the period ended June 30, 2000, the
portfolio was charged $13,556 pursuant to the custody agreement.

                                                                  The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

(b)  Each  board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus Board members, if any, receives 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.

NOTE 3--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$,160,809,026 and $77,658,502, respectively.

At  June  30,  2000,  accumulated net unrealized appreciation on investments was
$34,168,108,   consisting  of  $37,056,571  gross  unrealized  appreciation  and
$2,888,463    gross    unrealized    depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Founders  Growth  Portfolio,  covering  the  six-month  period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  portfolio  was managed during the reporting period, including a
discussion with its portfolio managers, Scott Chapman, CFA and Thomas Arrington,
CFA of Founders Asset Management LLC, the portfolio's sub-investment adviser.

While  stock prices were little changed on average over the past six months, the
period  was  marked by high levels of volatility and dramatic shifts in investor
sentiment.  Between  January and mid-March, large-cap stocks generally continued
to advance, led by fast-growing technology stocks that, many investors believed,
would  benefit  most  from  the "new economy." Subsequently, however, technology
stocks corrected sharply over concerns about rising interest rates and extremely
high  valuations.  Other  sectors  of  the large-cap stock market also declined,
erasing the gains achieved earlier in the year.

Also,  primarily  because  of  the  precipitous drop in technology stock prices,
value-oriented  stocks generally outperformed growth stocks during the reporting
period,  a  reversal  of  the  trend established over the past several years. In
addition,  small-capitalization  stocks generally outperformed large-cap stocks,
particularly  in  the  value-oriented  segment of the market. In our view, these
short-term  swings  in investor sentiment highlight once again the importance of
broad diversification and a long-term perspective for most investors.

We  appreciate  your confidence over the past six months, and we look forward to
your  continued  participation in Dreyfus Investment Portfolios, Founders Growth
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PEFORMANCE

Scott Chapman, CFA and Thomas Arrington, CFA,  Portfolio Managers Founders Asset
Management LLC, Sub-Investment Adviser

How did Dreyfus Investment Portfolios, Founders Growth Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Founders  Growth  Portfolio produced a total return of -3.72%.(1) In comparison,
the  portfolio's  benchmark,  the Standard & Poor's 500/BARRA Growth Index (the
"Index"), produced a total return of 2.63% for the same period.(2)

Midway  through  the reporting period, growth stocks suffered a sharp decline in
price, although the very largest companies were considered "safe havens" and did
not  decline as much. The primary reason for the portfolio's underperformance of
the  Index  during  the  reporting  period  is that the portfolio contained more
aggressive  growth  companies  that  sold off sharply during March and April. In
contrast,  the  Index  contained  larger,  less  volatile companies that did not
perform  as  well  when  the  market was gaining strength, but didn't perform as
poorly when the market was declining.

What is the portfolio's investment approach?

The  portfolio  invests  primarily in large, well-managed growth companies whose
performance  is  not  entirely  dependent  upon  the  fortunes  of  the economy.
Utilizing  a  bottom-up  approach, we focus on individual stock selection rather
than  on  forecasting  stock  market  trends.  We  look for high quality, proven
companies  with  an  established  track  record  of sustained earnings growth in
excess  of  industry  averages.  The companies we select must have a sustainable
competitive  advantage,  such  as a dominant brand name, a high barrier to entry
from  competition and/or large untapped market opportunities. Rather than having
a  short-term  focus  on  next  quarter' s profits, we look at a company for its
long-term potential and its earning power over the next three to five years.

                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

What other factors influenced the portfolio's performance?

At  the  beginning of the year growth stocks performed very strongly, continuing
the  trend from the fourth quarter of 1999. The acquisition by America Online of
TimeWarner  symbolized  the  dominance  of the "new economy" over the old, as an
Internet company acquired a well-established publishing firm.

In  March,  the  federal government's bid to break up Microsoft accelerated, and
other  technology  stocks  sold off in sympathy. In addition, investor sentiment
became  pessimistic  as  the Federal Reserve Board took a more aggressive stance
toward  raising  interest rates in an attempt to slow the economy. By the end of
the  first quarter, a shift away from high-priced growth stocks took place, even
though these companies reported strong profits. By June, technology stocks began
to recover when the U.S. economy appeared to be slowing.

Despite the volatility in technology stocks during the reporting period, many of
the  portfolio's best-performing stocks came from that sector. For example, JDS
Uniphase,  a  company  that  is replacing the world's 100-year-old voice-centric
telecommunications  system with a network that is designed to easily accommodate
data  traffic, was one of the portfolio's top performers. However, many Internet
companies  had  a  very  difficult  period,  as  investors  fled "dot.coms" that
reported  losses.  Even a profitable company like Yahoo, a competitor to America
Online,  essentially  gave  back  most  of its share price gains from the fourth
quarter of 1999.

Another strong area for the portfolio was health care, partly due to a number of
news events. First, scientists from the National Institute of Health and private
industry  announced  that they had deciphered the genetic code for human life, a
discovery  that  should  make it possible for companies to create more effective
drugs  to treat diseases. Second, the congressional debate over the expansion of
Medicare to cover prescription drugs -- viewed as a negative for the industry --
lost steam as the national election season approached.


Certain  stock  groups  produced  mixed  results,  such  as retail. For example,
Kohl's,  a  300-unit  chain  offering  midprice no-frills merchandise, produced
strong  gains  for the portfolio. However, Costco Wholesale's stock fell sharply
after the company announced that earnings growth was likely to fall.

What is the portfolio's current strategy?

The  portfolio  emphasizes  large-  and mid-capitalization growth companies that
provide  a  demonstrated  track record of sustainable earnings growth along with
what we believe are considerable competitive advantages.

Although  we focus on a five-year horizon when valuing companies, the reality is
that  in the short term, investor fears of higher rates often result in volatile
price  movements.  Yet  most of the companies in the portfolio have continued to
beat  Wall Street's expectations for earnings. In the final analysis, we believe
that  it is profitability that drives stock price performance for the long term,
not  short-term  market  sentiment.  Rather  than  becoming  overly concerned by
quarter-to-quarter volatility, our continuing strategy is to invest in companies
which we believe have strong long-term prospects.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company  operating  as  a  series  company currently offering twelve
series, including the Founders Growth Portfolio (the "portfolio"). The portfolio
is  only offered to separate accounts established by insurance companies to fund
variable  annuity  contracts and variable life insurance policies. The portfolio
is  a  diversified  series.  The  portfolio's investment objective is to provide
long-term  capital  growth.  The  Dreyfus  Corporation ("Dreyfus") serves as the
portfolio's  investment adviser. Dreyfus is a direct subsidiary of Mellon Bank,
N.A.  ("Mellon"), which  is  a  wholly-owned  subsidiary  of  Mellon Financial
Corporation.   Founders   Asset  Management  LLC  ("Founders") serves  as  the
portfolio's  sub-investment  adviser.  Founders  is  a  90%-owned subsidiary of
Mellon.  Effective  March  22,  2000,  Dreyfus  Service  Corporation  ("DSC"), a
wholly-owned  subsidiary  of  Dreyfus, became the distributor of the portfolio's
shares,  which are sold to the public without a sales charge. Prior to March 22,
2000, Premier Mutual Fund Services, Inc. was the distributor.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities  market,  or  securities  for  which  there were no transactions, are
valued at the average of the most recent
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

bid  and asked prices, except for open short positions, where the asked price is
used for valuation purposes. Bid price is used when no asked price is available.
Securities  for  which  there are no such valuations are valued at fair value as
determined  in  good  faith  under  the  direction  of  the  Board  of Trustees.
Investments  denominated in foreign currencies are translated to U.S. dollars at
the prevailing rates of exchange. Forward currency exchange contracts are valued
at the forward rate.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits  of $1,356 during the period ended June 30, 2000 based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.


(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Bank Line of Credit:

The  portfolio  participates  with other Dreyfus-managed funds in a $500 million
redemption  credit  facility  (the  "Facility" ) to be utilized for temporary or
emergency  purposes,  including  the  financing  of  redemptions.  In connection
therewith,  the  portfolio  has  agreed  to  pay commitment fees on its pro rata
portion  of the Facility. Interest is charged to the portfolio at rates based on
prevailing  market  rates in effect at the time of borrowings. During the period
ended June 30, 2000, the portfolio did not borrow under the Facility.

NOTE 3--Investment Advisory Fee, Sub-Investment Advisory Fee and Other
Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .75 of 1% of the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio's  aggregate annual expenses,
exclusive of taxes, brokerage
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

fees, interest on borrowings, commitment fees and extraordinary expenses, exceed
an  annual  rate of 1% of the value of the portfolio's average daily net assets.
The  reduction in investment advisory fee, pursuant to the undertaking, amounted
to $18,520 during the period ended June 30, 2000.

Pursuant   to   a   Sub-Investment   Advisory   Agreement   with  Founders,  the
sub-investment advisory fee is payable monthly by Dreyfus, and is based upon the
value  of  the  portfolio's average daily net assets, computed at the following
annual rates:

       AVERAGE NET ASSETS

       0 to $100 million. . . . . . . . . . . . . . . . . .     .25 of 1%

       In excess of $100 million to $1 billion. . . . . . .     .20 of 1%

       In excess of $1 billion to $1.5 billion. . . . . . .     .16 of 1%

       In excess of $1.5 billion. . . . . . . . . . . . . .     .10 of 1%

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was charged $15 pursuant to the
transfer agency agreement.

The  portfolio  compensates  Mellon  under  a  custody  agreement  for providing
custodial services for the portfolio. During the period ended June 30, 2000, the
portfolio was charged $9,731 pursuant to the custody agreement.

(B)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated   person"   as   defined   in  the  Act  received  from  the  fund
an  annual fee of $1,000 and an attendance fee of $250 per meeting. The Chairman
of  the  Board  received  an additional 25% of such compensation. Subject to the
fund's Emeritus Program Guidelines, Emeritus Board members, if any, receive 50%
of the fund's annual retainer fee and per meeting fee paid at the time the Board
member achieves emeritus status.

NOTE 4--Securities Transactions:

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Founders  International  Equity  Portfolio,  covering the six-month
period  from January 1, 2000 through June 30, 2000. Inside, you'll find valuable
information  about  how  the  portfolio was managed during the reporting period,
including  a discussion with the portfolio manager, Douglas A. Loeffler, CFA, of
Founders Asset Management LLC, the portfolio's sub-investment adviser.

When  the  reporting  period  began, it had become apparent that global economic
growth was substantially stronger than many analysts had expected. In fact, most
global  markets  had  already  rebounded sharply from 1998's currency and credit
crises  in emerging market countries. The rally continued into the first quarter
of 2000, before peaking in early March.

In  April,  many  developed  and  emerging  market  countries  around  the world
experienced  heightened  levels of volatility when expensively priced technology
stocks  began  to  decline  sharply  in  the  wake of evidence that inflationary
pressures  were  building.  This  correction, combined with a strong U.S. dollar
relative to many foreign currencies, erased much of the reporting period's early
gains.

We  appreciate  your confidence over the past six months, and we look forward to
your   continued   participation  in  Dreyfus  Investment  Portfolios,  Founders
International Equity Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Douglas A. Loeffler, CFA, Portfolio Manager Founders Asset Management LLC,
Sub-Investment Adviser

How did Dreyfus Investment Portfolios, Founders International Equity Portfolio
perform relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, the portfolio produced a total
return  of  -2.83%.(1)  This  compares with a -2.95% return for the portfolio's
benchmark,  the Morgan Stanley Capital International (MSCI) World ex U.S. Index,
for the same period.(2)

We attribute the portfolio's modest outperformance to successful stock selection
in  an  environment  that,  for  much of the reporting period, did not favor the
growth investment style.

What is the portfolio's investment approach?

The  portfolio  focuses  on  individual  stock  selection.  We do not attempt to
predict  interest  rates  or  market movements nor do we have country allocation
models  or targets. Rather, we choose investments on a company-by-company basis,
searching  to  find  what  we  believe  to  be the best-managed, best-positioned
companies, wherever they may be.

Starting  with roughly 1,000 of the largest companies outside the United States,
we  perform  rigorous stock-by-stock analyses. Our goal is to identify companies
that we believe have achieved and can sustain earnings or revenue growth through
a  strong  brand  name, growing market share, high barriers to entry or untapped
market  opportunities.  In  our  view,  these factors are the marks of companies
whose  growth,  in  both  revenues  and  earnings,  should exceed that of global
industry peers as well as that of their local markets.

The  portfolio  will  typically  hold  60-80  stocks,  broadly  invested  across
countries  and  industries,  representing  what we believe to be the best growth
ideas  in  the world. We generally sell a stock when it reaches its target price
or when we determine that circumstances have changed and it will most likely not
reach the previously set target sale price.

                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

What other factors influenced the portfolio's performance?

When  the  reporting  period  began,  the portfolio benefited from strong global
demand  for  growth stocks. After a brief January pause, the year-end 1999 rally
continued  into  the first quarter of 2000. The global advance was driven by the
telecommunications,  media  and  technology  industries,  on which the portfolio
placed a relatively heavy emphasis.

From mid-March through the end of May, however, global stock markets were marked
by  rapid swings and shifts in investor sentiment. Investors grew concerned over
stock  valuations  that  were  extraordinarily  high when compared to historical
norms.  Overseas  markets,  and  especially  the  emerging  markets, were highly
vulnerable  to  rising  interest  rates.  While demand for stocks remained high,
supply  grew  rapidly  as  firms  rushed  new  shares to market in order to take
advantage  of  high prices. However, investors paused to rethink valuations when
central banks raised interest rates and markets grew glutted with new issues. As
a   result,   stock  prices  turned  downward,  negatively  affecting  portfolio
performance.

More  specifically, Japan was weak through the entire reporting period; both the
market  and  economy continued to disappoint investors. However, our emphasis on
individual  stock selection helped the portfolio's performance. European markets
moved  slightly  ahead  in  local  currency  terms, benefiting the portfolio, as
countries continued to move away from a centralized economic model and towards a
competitive,  market-driven structure. However, weakness in the euro and British
pound  relative  to  the  U.S. dollar negatively affected the performance of the
portfolio's European investments for U.S. investors.

What is the portfolio's current strategy?

We  have  maintained  our  focus  during  a challenging period for global growth
stocks,  continuing  our  quest  to  uncover what we believe to be the strongest
growth opportunities worldwide.

Since  mid-March,  we  have  worked  to  reduce  the  overall  volatility of the
portfolio.   In   particular,   we   have  focused  on  the  price  we  pay  for
stocks,  looking  for  a clearer path from concept to profitability and reducing
our investment in stocks with no current earnings.

Accordingly,  Europe is currently our largest area of regional exposure. We have
reduced  our  investments  in European financial firms, concentrating instead on
companies  positioned  to  take  advantage  of  the  ongoing  convergence of the
telecommunications and entertainment industries. We de-emphasized investments in
the United Kingdom, avoiding exposure to its weak financial services industry.

Japan  continues  to be the portfolio's largest single-country weighting. In our
Japanese  investments,  we  have focused on selecting well-run companies that we
believe  are  positioned  for growth, including telecommunications companies and
high-end  consumer  electronics  manufacturers.  We  are  also  seeking  to take
advantage  of selected opportunities in emerging market countries. These include
Latin  American stocks tied closely to U.S. market performance, as well as Asian
manufacturers  of  semiconductors and telecommunications equipment. On the other
hand,  we  have  sharply  reduced  our  holdings  of commodity telecommunication
providers, particularly in markets with many new entrants. In the media industry
group,   we   are   focusing  primarily  on  company  valuations  and  potential
profitability.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company  operating  as  a  series  company currently offering twelve
portfolios,   including   the   Founders  International  Equity  Portfolio  (the
"portfolio"). The portfolio is only offered to separate accounts established by
insurance  companies  to  fund  variable  annuity  contracts  and  variable life
insurance  policies.  The  portfolio  is  a  diversified series. The portfolio's
investment  objective  is  to  provide  long-term  capital  growth.  The Dreyfus
Corporation ("Dreyfus") serves as the portfolio's investment adviser. Dreyfus is
a  direct  subsidiary  of  Mellon Bank, N.A. ("Mellon"), which is a wholly-owned
subsidiary  of  Mellon  Financial  Corporation.  Founders  Asset  Management LLC
("Founders") serves as the portfolio's sub-investment adviser. Founders is a 90%
-owned   subsidiary  of  Mellon.  Effective  March  22,  2000,  Dreyfus  Service
Corporation  ("DSC" ), a  wholly-owned  subsidiary  of  the Dreyfus, became the
distributor  of  the  portfolio's shares, which are sold to the public without a
sales  charge.  Prior  to March 22, 2000, Premier Mutual Fund Services, Inc. was
the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 179,367 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national   securities  market.  Securities  not  listed  on  an
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

exchange  or  the national securities market, or securities for which there were
no  transactions,  are  valued  at  the average of the most recent bid and asked
prices,  except  for  open  short  positions,  where the asked price is used for
valuation  purposes.  Bid  price  is  used  when  no  asked  price is available.
Securities  for  which  there are no such valuations are valued at fair value as
determined  in  good  faith  under  the  direction  of  the  Board  of Trustees.
Investments  denominated in foreign currencies are translated to U.S. dollars at
the prevailing rates of exchange. Forward currency exchange contracts are valued
at the forward rate.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits of $2,765 during the period ended June 30, 2000, based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.

(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Bank Line of Credit:

The  portfolio  participates  with other Dreyfus-managed funds in a $500 million
redemption  credit  facility  (the  "Facility" ) to be utilized for temporary or
emergency  purposes,  including  the  financing  of  redemptions.  In connection
therewith,  the  portfolio  has  agreed  to  pay commitment fees on its pro rata
portion  of the Facility. Interest is charged to the portfolio at rates based on
prevailing  market  rates in effect at the time of borrowings. During the period
ended June 30, 2000, the portfolio did not borrow under the Facility.

NOTE 3--Investment Advisory Fee, Sub-Investment Advisory Fee and Other
Transactions with Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at  the  annual  rate  of  1%  of  the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken   from   January   1,   2000  through  December  31,
                                                                  The  Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

2000,  to  reduce the investment advisory fee and reimburse such excess expenses
paid  by  the  portfolio,  to  the  extent that the portfolio's aggregate annual
expenses,  exclusive  of  taxes,  brokerage  fees,  interest  on  borrowings and
extraordinary  expenses,  exceed  an  annual  rate  of 1.50% of the value of the
portfolio's average daily net assets. The expense reimbursement, pursuant to the
undertaking, amounted to $39,349 during the period ended June 30, 2000.

Pursuant to a Sub-Investment Advisory Agreement with Founders, the
sub-investment advisory fee is payable monthly by Dreyfus, and is based upon the
value  of  the  portfolio's average daily net assets, computed at the following
annual rates:

          AVERAGE NET ASSETS

          0 to $100 million. . . . . . . . . . . . . . . . .      .35 of 1%

          In excess of $100 million to $1 billion. . . . . .      .30 of 1%

          In excess of $1 billion to $1.5 billion. . . . . .      .26 of 1%

          In excess of $1.5 billion. . . . . . . . . . . . .      .20 of 1%

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was charged $15 pursuant to the
transfer agency agreement.

(B) Each Board member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund Group. The Chairman of the Board receives an additional 25% of such
compensation. Prior to April 13, 2000, each Board member who was not an
"affiliated person" as defined in the Act received from the fund an annual fee
of $1,000 and an attendance fee of $250 per meeting. The Chairman of the Board
received an additional 25% of such compensation. Subject to the fund's Emeritus
Program Guidelines, Emeritus Board members, if any, receive 50% of the fund's
annual retainer fee and per meeting fee paid at the time the Board member
achieves emeritus status.

NOTE 4--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$10,524,287 and $6,652,202, respectively.

At  June  30,  2000,  accumulated net unrealized appreciation on investments was
$793,311,  consisting  of  $1,014,536 gross unrealized appreciation and $221,225
gross unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

                                                                   The Portfolio

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Founders  Passport  Portfolio,  covering  the six-month period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  portfolio  was managed during the reporting period, including a
discussion  with  its  portfolio  manager,  Tracy  Stouffer  of  Founders  Asset
Management LLC, the portfolio's sub-investment adviser.

When  the  reporting  period  began, it had become apparent that global economic
growth was substantially stronger than many analysts had expected. In fact, most
global  markets  had  already  rebounded sharply from 1998's currency and credit
crises  in emerging market countries. The rally continued into the first quarter
of 2000, before peaking in early March.

In April, the markets of many developed and emerging market countries around the
world  experienced  heightened  levels  of  volatility  when  expensively priced
technology  stocks  began  to  decline  sharply  in  the  wake  of evidence that
inflationary  pressures  were  building. This correction, combined with a strong
U.S.  dollar  relative  to many foreign currencies, erased much of the reporting
period's early gains.

We  appreciate  your confidence over the past six months, and we look forward to
your continued participation in Dreyfus Investment Portfolios, Founders Passport
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

July 17, 2000




DISCUSSION OF PERFORMANCE

Tracy Stouffer, Portfolio Manager Founders Asset Management LLC, Sub-Investment
Adviser

How did Dreyfus Investment Portfolios, Founders Passport Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Founders Passport Portfolio produced a total return of -5.26%.(1) In comparison,
the  portfolio's  benchmarks, the Morgan Stanley Capital International World ex
U.S.  Index(2)  and the Morgan Stanley Capital International World ex U.S. Small
Cap  Index,(3) produced total returns of -2.95% and 5.00%, respectively, for the
same period.

We  attribute  the  portfolio's  underperformance  of  the  indices  during the
reporting period to the volatility in international "new economy" stocks such as
technology,  telecommunications  and media, which performed in line with similar
companies  in  the United States. Between March and May of 2000, stock prices of
these  companies  declined  sharply  due  to  concerns regarding their very high
levels  as  well  as  fears of inflation and a rising interest-rate environment.

What is the portfolio's investment approach?

The  portfolio  invests  primarily  in foreign companies with annual revenues or
market  capitalizations  of  $1  billion  or  less that have demonstrated strong
earnings growth as well as dominance in their market niches. Although our recent
focus  has  been  on technology and telecommunications, the portfolio is broadly
diversified and currently holds more than 100 stocks in many industries.

Because  of  this  broad mandate, we believe it is very important for us to meet
with  corporate  management  teams  to assess their business strategies. We also
believe  it is important to travel to the countries in which they are located to
assess  the local business environment. When it comes to international small-cap
stocks, it is especially important to learn as much as we can because there is a
limited amount of Wall Street research available on many of these companies.

                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

What other factors influenced the portfolio's performance?

The reporting period began on a positive note. The much anticipated Y2K concerns
never  materialized and international fund managers who had a high level of cash
reserves  were  able  to  put  the  money  to  work  early  in the year. In this
environment,  small-cap  stocks  flourished, as investors were willing to assume
additional risk in return for higher return potential.

However,  in  early March the U.S. stock market turned volatile when it appeared
that  the  domestic  economy  was growing too fast to keep inflation at bay. The
Federal  Reserve  Board  (the  "Fed" ) responded  by raising short-term interest
rates.  A  "flight  to size" ensued during which the hardest hit stocks were the
small  caps.  Often,  we  found  it  difficult  to sell these shares on the open
market, and this lack of liquidity caused share prices to fall sharply.

Not  all  stocks in the portfolio fell in value during the period. The companies
that  tended  to  perform well posted stronger than expected earnings during the
period.  One  example  was  Logitech  International,  a Swiss company that makes
computer accessories such as PC video cameras and multimedia speakers. Indeed, a
number  of  Swiss  companies performed well, not just because of strong profits,
but  because  there  is a new small-cap stock index in Switzerland that makes it
easier  for  Swiss  investors  to  participate  in  the  small-cap  marketplace.

The Chinese stock market also produced strong returns as that nation experienced
an  economic  recovery. The portfolio's economically cyclical holdings generally
performed  well in an improving business environment. One example: Huaneng Power
International,  a  leading  electric  utility,  is  benefiting  from  increasing
economic  activity  in  China.  Another  example is China Eastern Airlines Ltd.,
which  can benefit from rising per capita income throughout China as trade opens
up with the West.


Other  strong  stocks  in  the portfolio in the reporting period were profitable
companies  in  a  variety  of  industries  and locations, such as a construction
company  in  France, a doll manufacturer in Germany and a semiconductor designer
in Ireland.

What is the portfolio's current strategy?

Our  current  strategy  is  to  continue to focus on finding small, fast-growing
companies throughout the world regardless of industry or location. Currently, we
like the valuation in Asia and the larger markets of Europe.

Finally, we continue to actively pursue stocks of companies in new technologies.
Although  the  first  half  of  2000  was a volatile period for these stocks, we
believe  that  in  general,  new  economy  companies offer great opportunity for
growth.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company,  operating  as  a  series company currently offering twelve
series,   including  the  Founders  Passport  Portfolio  (the  "portfolio) . The
portfolio  is  only  offered  to  separate  accounts  established  by  insurance
companies  to  fund  variable  annuity  contracts  and  variable  life insurance
policies.  The  portfolio  is  a  diversified series. The portfolio's investment
objective is capital appreciation. The Dreyfus Corporation ("Dreyfus") serves as
the  portfolio's  investment  adviser. Dreyfus is a direct subsidiary of Mellon
Bank,  N.A.  ("Mellon"), which is a wholly-owned subsidiary of Mellon Financial
Corporation.   Founders   Asset  Management  LLC  ("Founders") serves  as  the
portfolio's  sub-investment  adviser.  Founders  is  a  90%-owned subsidiary of
Mellon.  Effective  March  22,  2000,  Dreyfus  Service  Corporation  ("DSC"), a
wholly-owned  subsidiary  of  Dreyfus, became the distributor of the portfolio's
shares,  which are sold to the public without a sales charge. Prior to March 22,
2000, Premier Mutual Fund Services, Inc. was the distributor.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities  market,  or  securities  for  which  there were no transactions, are
valued at the average of the most recent bid and asked prices, except for open
short positions, where the asked price is used for valuation purposes. Bid price
is used when no asked price is available. Securities for which there are no such
valuations are valued at fair value as determined in good faith under the
direction of the Board of Trustees. Investments denominated in foreign
currencies are translated to U.S. dollars at the prevailing rates of exchange.
Forward currency exchange contracts are valued at the forward rate.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest and foreign withholding taxes recorded on the Series' books
and  the  U.S.  dollar  equivalent of the amounts actually received or paid. Net
unrealized  foreign  exchange gains or losses arise from changes in the value of
assets  and  liabilities  other  than  investments  in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits  of $5,444 during the period ended June 30, 2000 based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.

                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Bank Line of Credit:

The  portfolio  participates  with other Dreyfus-managed funds in a $500 million
redemption  credit  facility  (the  "Facility" ) to be utilized for temporary or
emergency  purposes,  including  the  financing  of  redemptions.  In connection
therewith,  the  portfolio  has  agreed  to  pay commitment fees on its pro rata
portion  of the Facility. Interest is charged to the portfolio at rates based on
prevailing  market  rates in effect at the time of borrowings. During the period
ended June 30, 2000, the portfolio did not borrow under the Facility.

NOTE 3--Investment Advisory Fee, Sub-Investment Advisory Fee and Other
Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at  the  annual  rate  of  1%  of  the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio's  aggregate  annual expenses
exclusive  of  taxes,  brokerage  fees, interest on borrowings and extraordinary
expenses, exceed an annual rate of 1.50% of the value of the portfolio's
average daily net assets. The expense reimbursement, pursuant to the
undertaking, amounted to $275,473 during the period ended June 30, 2000.

Pursuant   to   a   Sub-Investment   Advisory   Agreement   with  Founders,  the
sub-investment  advisory  fees are payable monthly by Dreyfus, and is based upon

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  European  Equity  Portfolio,  covering  the  six-month  period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  fund  was  managed  during  the  reporting  period, including a
discussion with the portfolio manager, Joanna Bowen of Newton Capital Management
Limited, the portfolio's sub-investment adviser.

When  the  reporting  period  began, it had become apparent that global economic
growth was substantially stronger than many analysts had expected. In fact, most
global  markets  had  already  rebounded sharply from 1998's currency and credit
crises  in emerging market countries. The rally continued into the first quarter
of 2000, before peaking in early March.

In  April,  many  developed  and  emerging  market  countries  around  the world
experienced  heightened  levels of volatility when expensively priced technology
stocks  began  to  decline  sharply  in  the  wake of evidence that inflationary
pressures  were  building.  This  correction, combined with a strong U.S. dollar
relative to many foreign currencies, erased much of the reporting period's early
gains.

We  appreciate  your confidence over the past six months, and we look forward to
your  continued  participation in Dreyfus Investment Portfolios, European Equity
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Joanna Bowen, Portfolio Manager Newton Capital Management Limited,
Sub-Investment Adviser

How did Dreyfus Investment Portfolios, European Equity Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
European  Equity Portfolio produced a total return of 2.45%.(1) In contrast, the
Financial  Times  Eurotop  300 Index, which serves as the portfolio's benchmark,
returned -3.52% in U.S. dollar terms for the same period.(2)

The  portfolio's performance was positively impacted by two factors. First, the
portfolio's  emphasis  on  technology,  telecommunications  and  media  boosted
performance  during  the  first  quarter  of  2000.  Second,  a  shift  to  more
value-oriented  stocks  cushioned  the portfolio during the sharp second-quarter
downturn  in  the  European stock market. However, the euro's continuing decline
relative to the U.S. dollar adversely affected performance.

What is the portfolio's investment approach?

The  portfolio,  which  seeks  to  outperform  the European stock market in U.S.
dollar  terms,  invests  primarily  in  the  300  largest European companies. We
identify  investment  themes,  such  as  the  impact  of new technologies, aging
populations  and  the communications revolution and long-term trends in currency
movements. We invest in companies that we believe are best positioned to benefit
from  these  trends.  Within  markets  and  sectors, we seek attractively priced
companies  that  possess  a  sustainable  competitive advantage. In addition, we
attempt  to identify and forecast key economic variables, such as gross domestic
product, inflation and interest rates.

What other factors influenced the portfolio's performance?

The  euro,  which  began  the year at about $1.02, ended the six-month period at
about 94 cents to the dollar.  Stated another way, a U.S.
                                                                  The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

investor who bought a portfolio of European stocks on January 1, 2000 would have
lost  about  8  percent  in dollar terms, even if the European stocks, which are
measured  in  euros,  stayed  the  same price. The primary reason for the euro's
decline  versus  the  dollar  is  that  the  United States has been growing more
rapidly and attracting more investment capital from around the world.

Indeed,  the  linkage  between Europe and the U.S. goes beyond currency. Many of
Europe's  leading  companies  share the same trends as their U.S. counterparts.
When  market  sectors, such as technology, decline in the U.S., a similar effect
takes place in Europe. The key to stock market performance during the first half
of 2000 was to take advantage of rising prices in technology, telecommunications
and  media  during  the  first  quarter,  while selling shares in these holdings
before  they  fell  sharply  in  March  and  April. For example, the portfolio's
position  in  the  large  telephone  companies  was  lower  than the benchmark's
weighting  because  valuations  had  become  extended  and we believed increased
competition was a risk that could erode profitability.

However,  certain  areas of technology held up better in the second quarter, and
the  portfolio  benefited  from  holding, rather than selling, these stocks. For
instance, Telefonaktiebolaget LM Ericsson, a manufacturer of wireless phones and
infrastructure,  continued  to  benefit  from  the demand for wireless telephony
infrastructure. Koninklijke (Royal) Philips Electronics, with its large exposure
to semiconductors, also held up well.

By  and  large, the portfolio's best-performing stocks in the second part of the
period  were  "defensive," meaning they provided protection during the downturn.
Examples  included  Koninklijke Numico, a Netherlands-based company specializing
in baby food and nutritional supplements, and Koninklijke Ahold, a food retailer
with  more  than  3,600 stores primarily in the Netherlands and the U.S. Another
profitable  move  was  purchasing  pharmaceutical  stocks,  which had lagged the
market.  The  portfolio  holds two German healthcare companies: Fresenius, which
operates  kidney  dialysis  centers  in  Europe  and  the  U.S.,  and  Altana, a
pharmaceutical company with some chemicals operations.


What is the portfolio's current strategy?

Given  the  euphoria  of  the first quarter and the correction of the second, we
believe  the market will increasingly focus on stock fundamentals. The portfolio
continues  to  concentrate  on investing in stocks that, in our opinion, provide
growth  at  a  reasonable  valuation  and with relatively low risk. The fund has
adopted  a  more  sector-neutral  stance.  However,  the  portfolio continues to
underweight  banks  where  we  believe  the intense competitive environment will
continue  to  impact  margins  and  stock valuations. Pricing continues to be an
important  theme  and  the fund makes efforts to make investments in stocks with
pricing  power  and  avoid those companies that suffer from pricing competition.
For  example,  Italy's  cement  market  has become more attractive to investors
because  it  has  recently  consolidated  through  mergers,  resulting in better
pricing and, therefore, greater profitability for the companies that remain.

Technology,  telecommunications  and  media  stocks  were  volatile  during  the
reporting  period.  Recently the portfolio has taken advantage of the correction
in  the telecommunications sector to increase weightings. Information technology
service  companies  are  also looking more attractive at these valuation levels.
The  fund  continues  to  hold an overweighted position in these sectors through
holdings in stocks that we believe offer good growth prospects.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act"), as  an  open-end management
investment  company  operating  as  a  series  company currently offering twelve
series, including the European Equity Portfolio (the "portfolio"). The portfolio
is  only offered to separate accounts established by insurance companies to fund
variable  annuity  contracts and variable life insurance policies. The portfolio
is  a  diversified  series.  The  portfolio's investment objective is to provide
long-term  capital  growth.  The  Dreyfus  Corporation ("Dreyfus") serves as the
portfolio's  investment adviser. Dreyfus is a direct subsidiary of Mellon Bank,
N.A.  which is a wholly-owned subsidiary of Mellon Financial Corporation. Newton
Capital  Management  Limited  ("Newton"), an affiliate of Dreyfus, serves as the
portfolio's  sub-investment  adviser. Effective March 22, 2000, Dreyfus Service
Corporation   ("DSC"), a  wholly-owned  subsidiary  of  Dreyfus,  became  the
distributor  of  the  portfolio's shares, which are sold to the public without a
sales  charge.  Prior  to March 22, 2000, Premier Mutual Fund Services, Inc. was
the distributor.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(a)  Portfolio  valuation:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities  market,  or  securities  for  which  there were no transactions, are
valued at the average of the most recent
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

bid  and asked prices, except for open short positions, where the asked price is
used for valuation purposes. Bid price is used when no asked price is available.
Securities  for  which  there are no such valuations are valued at fair value as
determined  in  good  faith  under  the  direction  of  the  Board  of Trustees.
Investments  denominated in foreign currencies are translated to U.S. dollars at
the prevailing rates of exchange. Forward currency exchange contracts are valued
at the forward rate.

(b)  Foreign  currency transactions: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(c)  Securities  transactions and investment income: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings credits of $32,009 during the period ended June 30, 2000, based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.


(d)  Dividends  to shareholders: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(e)  Federal  income  taxes:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee, Sub-Investment Advisory Fee and Other
Transactions With Affiliates:

(a)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at  the  annual  rate  of  1%  of  the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus had
undertaken  from  January  1,  2000  through  February  29,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio's  aggregate annual expenses,
exclusive  of  taxes,  brokerage  fees, interest on borrowings and extraordinary
expenses,  exceeded  an  annual  rate  of  1.50% of the value of the portfolio's
average  daily  net assets, and thereafter, through December 31, 2000, to reduce
the  investment  advisory  fee  and  reimburse  such excess expenses paid by the
portfolio,  to  the  extent  that  the  portfolio's  aggregate  annual expenses
(exclusive  of  certain  expenses  as  described above) exceed an annual rate of
1.25% of the value of the portfolio's average daily net assets. The reduction in
investment  advisory  fee,  pursuant  to  the  undertakings, amounted to $39,827
during the period ended June 30, 2000.

                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

Pursuant  to a Sub-Investment Advisory Agreement between Dreyfus and Newton, the
sub-investment fee is payable monthly by Dreyfus, and is based upon the value of
the  portfolio's  average  daily  net  assets, computed at the following annual
rates:

          Average Net Assets

          0 to $100 million. . . . . . . . . . . . . . . . .      .35 of 1%

          In excess of $100 million to $1 billion. . . . . .      .30 of 1%

          In excess of $1 billion to $1.5 billion. . . . . .      .26 of 1%

          In excess of $1.5 billion. . . . . . . . . . . . .      .20 of 1%

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio was charged $100 pursuant to the
transfer agency agreement.

(b)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.



NOTE 3--Securities Transactions:

(a)  The  aggregate  amount  of  purchases  and  sales of investment securities,
excluding  short-term securities and forward currency exchange contracts, during
the  period  ended  June  30,  2000,  amounted  to  $25,334,440 and $12,963,042,
respectively.

The  portfolio enters into forward currency exchange contracts in order to hedge
its  exposure  to  changes  in  foreign  currency  exchange rates on its foreign
portfolio  holdings  and to settle foreign currency transactions. When executing
forward currency exchange contracts, the portfolio is obligated to buy or sell a
foreign  currency  at  a  specified  rate  on a certain date in the future. With
respect  to  sales  of  forward currency exchange contracts, the portfolio would
incur a loss if the value of the contract increases between the date the forward
contract  is  opened  and the date the forward contract is closed. The portfolio
realizes a gain if the value of the contract decreases between those dates. With
respect to purchases of forward currency exchange contracts, the portfolio would
incur a loss if the value of the contract decreases between the date the forward
contract  is  opened  and the date the forward contract is closed. The portfolio
realizes  a gain if the value of the contract increases between those dates. The
portfolio  is  also  exposed  to  credit  risk  associated  with  counter  party
nonperformance  on  these forward currency exchange contracts which is typically
limited  to  the  unrealized gain on each open contract. At June 30, 2000, there
were no forward currency exchange contracts outstanding.

(b) At June 30, 2000, accumulated net unrealized appreciation on investments was
$527,596,  consisting  of  $1,306,131 gross unrealized appreciation and $778,535
gross unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

                                                                  The Portfolio

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Japan Portfolio, covering the six-month period from January 1, 2000
through  June  30,  2000. Inside, you'll find valuable information about how the
portfolio  was  managed during the reporting period, including a discussion with
the portfolio manager, Miki Sugimoto.

When  the  reporting  period  began, it had become apparent that global economic
growth was substantially stronger than many analysts had expected. In fact, most
global  markets  had  already  rebounded sharply from 1998's currency and credit
crises  in emerging market countries. The rally continued into the first quarter
of 2000, before peaking in early March.

In  April,  many  developed  and  emerging  market  countries  around  the world
experienced  heightened  levels of volatility when expensively priced technology
stocks  began  to  decline  sharply  in  the  wake of evidence that inflationary
pressures  were  building.  This  correction, combined with a strong U.S. dollar
relative to many foreign currencies, erased much of the reporting period's early
gains.

We  appreciate  your confidence over the past six months, and we look forward to
your continued participation in Dreyfus Investment Portfolios, Japan Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

July 17, 2000




DISCUSSION OF PERFORMANCE

Miki Sugimoto, Portfolio Manager

How did Dreyfus Investment Portfolios, Japan Portfolio perform relative to its
benchmark?

For  the  six-month  period  ended  June 30, 2000 Dreyfus Investment Portfolios,
Japan  Portfolio  produced  a  total return of 16.84%.(1) This compares with the
-5.37%  total return provided by the Morgan Stanley Capital International (MSCI)
Japan Index, the portfolio's benchmark, for the same period.(2)

We  attribute  the  portfolio's strong performance to our move away from stocks
with  relatively  high  valuations and our emphasis on low-valued stocks that we
believe  have the ability to achieve reasonable earnings growth. In addition, in
early  March  the  portfolio  benefited  from a wave of initial public offerings
(IPOs)  within  the small-cap stock market sector. Investors should note that as
the  portfolio's  asset  base  increases,  IPOs are likely to have a diminished
effect on the portfolio's performance.

What is the portfolio's investment approach?

The portfolio seeks long-term capital growth. To pursue this goal, the portfolio
invests  primarily  in  stocks  of  Japanese companies. Generally, the portfolio
invests   at  least  60%  of  its  assets  in  Japanese  companies  with  market
capitalizations  of  at  least  $1.5  billion  at  the  time  of investment. The
portfolio's  investments  may include common, preferred and convertible stocks,
including those purchased through IPOs.

The portfolio manager utilizes a "top-down," theme-driven investment approach to
stock  selection.  The  portfolio  manager  first  attempts  to identify overall
economic  trends,  and  then begins to narrow the search to industry groups that
are  believed  to have the potential to benefit from these trends. The portfolio
manager  also  considers  economic variables, such as the relative valuations of
equities  and bonds, and trends in the currency exchange markets. The investment
themes  and  economic  variables  provide  a framework for the portfolio's stock
selection    process.

We  consider  three  primary  criteria  when selecting stocks for the portfolio.
First,  we  look  either  for  industries with positive long-term
                                                                  The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

outlooks  or industries that are undergoing dramatic change. Second, we look for
companies  with quality management teams and strong franchises. Third, we strive
to  identify  high  quality  companies with high intrinsic values as measured by
fundamental valuation criteria such as earnings outlook, business prospects, and
asset values.

What other factors influenced the portfolio's performance?

During  the past six months the portfolio emphasized two investment themes, both
of  which  have  positively  affected performance. First, we favored stocks with
lower  valuations  and reasonable earnings growth, primarily within the non-bank
finance  and  pharmaceutical  sectors.  Second,  we  preferred  stocks that have
benefited  from  the  Japanese  recovery,  particularly those within the capital
expenditure sector that stand to benefit from an improving euro currency.

From  mid-February  to  mid-April, the global equity markets experienced a sharp
correction  in  many  telecommunications, media and technology companies. During
this  period,  we  began  to shift the portfolio's emphasis away from the higher
priced  stocks in these areas and toward companies that had lower valuations and
reasonable  earnings  growth. With that in mind, we found many attractive stocks
within  the  non-bank consumer finance sector. Despite generally strong earnings
growth,  the sector traded on a low earnings multiple due to investors' concerns
over changes in Japanese regulations that lowered the maximum lending ability of
individual  finance  companies  from  40%  to  29%  of  their total assets. This
regulatory  change  was  intended  to allow smaller finance companies to be more
competitive  with  the  larger,  well-established finance companies. We believed
that  investors'  concerns  were  largely  unfounded and that share prices would
eventually begin to reflect companies' earnings growth.

The pharmaceutical sector was another area in which the portfolio benefited from
this theme. By focusing on relatively low-priced stocks, we were able to achieve
attractive returns from holdings such as Daiichi Pharmaceutical, a company whose
stock  price  had  fallen  because it postponed the release of several new drugs
last  year.  We also benefited from our investment in Nippon Shinyaku, a company
whose  name  translates  to  "Japan's new drug." As a small company, we believe

Nippon   Shinyaku   is   an   excellent  candidate  for  merger-and-acquisitions
activities,  which  are  occurring  more  frequently within this industry group.
Overall,  the  pharmaceutical  sector  may  benefit  from the prospect of market
consolidation,  as  many  foreign pharmaceutical companies are looking to expand
into  Japan,  which  is  the  world' s  second-largest  pharmaceutical  market.

Our  second  theme,  emphasizing  stocks  that  are benefiting from a recovering
Japanese  economy  and  are directly tied into the euro, led us to stocks within
the  capital  expenditure  sector, primarily larger cap machinery companies that
depend  on  exports for revenues. For example, we benefited from our holdings in
Komori,  a  printing  company that exports one-third of its goods to Europe, and
Makita,  a  drilling  company  that also depends heavily on its export business.

What is the portfolio's current strategy?

In  an  uncertain  investment  environment,  we continue to favor companies with
lower  valuations  and  reasonable earnings growth, particularly those companies
within the non-bank financial and pharmaceutical sectors.

In  addition, we are closely monitoring the U.S. economy and its equity markets.
In today's globalized investment environment, the U.S. is one of Japan's largest
markets  and  we  are  keeping a watchful eye for any changes that could have an
effect  on  Japan' s export business over the near term. In the meantime, we are
pleased with the economic recovery that has taken place in Japan during the past
six  months,  particularly  within  the  larger  cap industrial sectors, and are
optimistic about Japan' s prospects going forward.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company  operating  as  a  series  company currently offering twelve
series,  including  the Japan Portfolio (the "portfolio"). The portfolio is only
offered to separate accounts established by insurance companies to fund variable
annuity  contracts  and  variable  life  insurance  policies. The portfolio is a
diversified series. The portfolio's investment objective is to provide long-term
capital  growth.  The  Dreyfus Corporation ("Dreyfus") serves as the portfolio's
investment  adviser.  Dreyfus  is  a  direct  subsidiary  of  Mellon  Bank, N.A.
("Mellon"), which is a wholly-owned subsidiary of Mellon Financial Corporation.
Newton  Capital Management Limited ("Newton") an affiliate of Dreyfus, serves as
the  portfolio's  sub-investment  adviser.  Effective  March  22, 2000, Dreyfus
Service  Corporation  ("DSC"), a wholly-owned subsidiary of Dreyfus, became the
distributor  of  the  portfolio's shares which are sold to the public without a
sales  charge.  Prior  to March 22, 2000, Premier Mutual Fund Services, Inc. was
the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 160,440 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities market, or securities for which there were no transactions, are
valued at the average of the most recent bid and asked prices, except for open
short positions, where the asked price is used for valuation purposes. Bid price
is used when no asked price is available. Securities for which there are no such
valuations are valued at fair value as determined in good faith under the
direction of the Board of Trustees. Investments denominated in foreign
currencies are translated to U.S. dollars at the prevailing rates of exchange.
Forward currency exchange contracts are valued at the forward rate.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized    gain    or    loss    from    investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net earnings credits of
                                                                  The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

$1,931  based  on  available  cash balances left on deposit. Income earned under
this arrangement is included in interest income.

(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain,  are  normally  declared  and  paid  annually,  but the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee, Sub-Investment Advisory Fee and Other
Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at  the  annual  rate  of  1%  of  the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio's  aggregate annual expenses,
exclusive  of  taxes,  brokerage  fees, interest on borrowings and extraordinary
expenses, exceed an annual rate of 1.50% of the value of the portfolio's average
daily  net  assets.  The  expense  reimbursement,  pursuant  to the undertaking,
amounted to $25,619 during the period ended June 30, 2000.

Pursuant to a Sub-Investment Advisory Agreement between Dreyfus and Newton, the
sub-investment advisory fees are payable monthly by Dreyfus, and are based upon
the value of the portfolio's average daily net assets, computed at the following
annual rates:

          AVERAGE NET ASSETS

          0 to $100 million. . . . . . . . . . . . . . . . .      .35 of 1%

          In excess of $100 million to $1 billion. . . . . .      .30 of 1%

          In excess of $1 billion to $1.5 billion. . . . . .      .26 of 1%

          In excess of $1.5 billion. . . . . . . . . . . . .      .20 of 1%

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities to perform transfer agency services for the portfolio.

(B)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 25, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  25,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.

NOTE 3--Securities Transactions:

(A)  The  aggregate  amount  of  purchases  and  sales of investment securities,
excluding  short-term  securities  and  forward currency exchange
                                                                 The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

contracts,  during  the  period  ended June 30, 2000, amounted to $5,001,434 and
$5,016,085, respectively.

The  portfolio enters into forward currency exchange contracts in order to hedge
its  exposure  to  changes  in  foreign  currency  exchange rates on its foreign
portfolio  holdings  and to settle foreign currency transactions. When executing
forward currency exchange contracts, the portfolio is obligated to buy or sell a
foreign  currency  at  a  specified  rate  on a certain date in the future. With
respect  to  sales  of  forward currency exchange contracts, the portfolio would
incur a loss if the value of the contract increases between the date the forward
contract  is  opened  and the date the forward contract is closed. The portfolio
realizes a gain if the value of the contract decreases between those dates. With
respect to purchases of forward currency exchange contracts, the portfolio would
incur a loss if the value of the contract decreases between the date the forward
contract  is  opened  and the date the forward contract is closed. The portfolio
realizes  a gain if the value of the contract increases between those dates. The
portfolio  is  also  exposed  to  credit  risk  associated  with  counter  party
nonperformance  on  these forward currency exchange contracts which is typically
limited  to  the  unrealized gain on each open contract. At June 30, 2000, there
were no forward currency exchange contracts outstanding.

(B) At June 30, 2000, accumulated net unrealized appreciation on investments was
$175,717, consisting of $244,568 gross unrealized appreciation and $68,851 gross
unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Emerging  Markets  Portfolio,  covering  the  six-month period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  portfolio  was managed during the reporting period, including a
discussion with the portfolio manager, Daniel Beneat.

When  the  reporting  period  began, it had become apparent that global economic
growth was substantially stronger than many analysts had expected. In fact, most
global  markets  had  already  rebounded sharply from 1998's currency and credit
crises  in emerging market countries. The rally continued into the first quarter
of 2000, before peaking in early March.

In  April,  many  developed  and  emerging  market  countries  around  the world
experienced  heightened  levels of volatility when expensively priced technology
stocks  began  to  decline  sharply  in  the  wake of evidence that inflationary
pressures  were  building.  This  correction, combined with a strong U.S. dollar
relative to many foreign currencies, erased much of the reporting period's early
gains.

We  appreciate  your confidence over the past six months, and we look forward to
your continued participation in Dreyfus Variable Investment Portfolios, Emerging
Markets Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

July 17, 2000




DISCUSSION OF PERFORMANCE

Daniel Beneat, Portfolio Manager

How did Dreyfus Investment Portfolios, Emerging Markets Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Emerging  Markets  Portfolio produced a total return of -7.54%.(1) This compares
with  the  -8.97%  total  return  provided  by  the fund's benchmark, the Morgan
Stanley  Capital  International  Emerging Markets Free (MSCI EMF) Index, for the
same period.(2)

We  attribute  the  portfolio's  performance  to  a  stock  market  environment
characterized  by high levels of volatility within emerging market countries. In
response  to  this  volatility,  we  began  shifting the portfolio's emphasis in
mid-March 2000, moving away from Asia and toward Europe. In addition, we shifted
emphasis  away  from small-cap to large-cap, more liquid companies. These shifts
caused the portfolio to slightly outperform its benchmark.

What is the portfolio's investment approach?

The  portfolio  seeks  long-term  capital  growth  by investing primarily in the
stocks  of  companies organized, or with a majority of their assets or business,
in  emerging market countries. Normally, the portfolio will not invest more than
25%  of  its  total assets in the securities of companies in any single emerging
market country.

When  selecting stocks for the portfolio, we use a "top-down" country allocation
approach.  We  strive  to  identify  and  forecast key trends in global economic
variables,  such  as  gross  domestic  product,  inflation  and  interest rates;
investment  themes, such as the impact of new technologies and the globalization
of  industries and brands; relative values of equity securities, bonds and cash;
and long-term trends in currency movements.

Within  those  countries,  we  use  a "bottom-up" approach to company and sector
analysis, which focuses on companies that we believe are attractively priced and
possess sustainable competitive advantage in
                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

their  country  or  sector.  Our  security-selection  approach  evaluates growth
factors  on  a  company-by-company  basis,  looking  at  factors such as revenue
prospects,  operating  cash  flow,  ability  to  achieve consistent earnings and
management's ability to achieve higher operating margins.

What other factors influenced the portfolio's performance?

At  the beginning of the reporting period, the emerging markets experienced high
levels  of  volatility,  primarily  due  to  two  factors:  a  shift in investor
sentiment  and a rising interest-rate environment in the United States. Investor
sentiment  began  to  shift  away  from  emerging markets after leading economic
indicators  hinted  that  a  slowdown  in  the  U.S.  was  likely.  In  such  an
environment,  many  industry analysts became concerned that slower growth in the
U.S. might adversely affect investments in other regions.

As  interest  rates  continued  to  rise in the U.S., exports from many emerging
nations  declined.  As  a  result,  stock prices and the portfolio's performance
suffered.  By  mid-March,  investor sentiment shifted once again, this time away
from the previously favored growth style of investing and toward the value style
of  investing. As a result, many technology and telecommunications stocks, which
produced  the highest returns during the first three months of the year, quickly
fell  out  of favor. For example, several of the portfolio's technology holdings
in  Taiwan, Korea, and to a lesser degree telecom companies in Brazil, were hurt
during  this  period.  In response, we trimmed our exposure in these areas. As a
result, our performance improved from mid-March through the end of the reporting
period, allowing the fund to recapture some of its previous gains.

What is the portfolio's current strategy?

We  have  focused  our asset-allocation strategy primarily on investments in the
European  region.  This  stance  is  based on our belief that European economies
should improve if the U.S. economy slows down. We have also emphasized large-cap
names  because  we believe that they tend to perform better than their small-cap
counterparts in more volatile market environments.

In  addition, we have increased our exposure to South Africa, where the currency
is linked to the euro. Because South Africa exports most of its goods to Europe,
this  emphasis ties directly into our strategy of tilting the portfolio in favor
of Europe.

At  this  time,  we  are  favoring investments in Brazil, where we are currently
emphasizing  telecommunications and commodity-oriented stocks, such as paper and
steel  companies. We have also enjoyed successes from several of our investments
in  Mexico  and  Chile,  where  we  believe  stock  prices  are very reasonable

Conversely,  we  have  limited our holdings in Southeast Asia -- particularly in
Korea,  China  and  Hong  Kong.  In  Korea, two large hedge funds were forced to
liquidate  a  large  portion  of  their equity holdings, which resulted in lower
stock  prices  in  many  large-cap  names. In China and Hong Kong, we are having
difficulties finding companies that offer adequate liquidity.

Finally,  we  are  currently maintaining our diversification strategy, spreading
investments  within  the portfolio across numerous countries and industry groups
in seeking investment opportunities for our shareholders.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company,  operating  as  a  series company currently offering twelve
series,   including  the  Emerging  Markets  Portfolio  (the  "portfolio" ). The
portfolio  is  only  offered  to  separate  accounts  established  by  insurance
companies  to  fund  variable  annuity  contracts  and  variable  life insurance
policies.  The portfolio is a non-diversified series. The portfolio's investment
objective  is  to  provide  long-term  capital  growth.  The Dreyfus Corporation
("Dreyfus" ) serves  as the portfolio's investment adviser. Dryefus is a direct
subsidiary  of  Mellon  Bank, N.A., which is a wholly-owned subsidiary of Mellon
Financial  Corporation.  Effective  March  22, 2000, Dreyfus Service Corporation
("DSC"), a  wholly-owned  subsidiary of Dreyfus, became the distributor of the
portfolio's shares which are sold to the public without a sales charge. Prior to
March 22, 2000, Premier Mutual Fund Services, Inc. was the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 160,407 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities market, or securities for which there were no transactions, are
valued at the average of the most recent bid and asked prices, except for open
short positions, where the asked price is used for valuation purposes. Bid price
is used when no asked price is available. Securities for which there are no such
valuations are valued at fair value as determined in good faith under the
direction of the Board of Trustees. Investments denominated in foreign
currencies are translated to U.S. dollars at the prevailing rates of exchange.
Forward currency exchange contracts are valued at the forward rate.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits  of  $1,962  for the period ended June 30, 2000, based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.

                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee and Other Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at  the  annual  rate  of 1.25% of the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio's  aggregate annual expenses,
exclusive  of  taxes,  brokerage  fees, interest on borrowings and extraordinary
expenses,  exceed  an  annual rate of 2% of the value of the portfolio's average
daily  net  assets.  The  expense  reimbursement,  pursuant  to the undertaking,
amounted to $21,550 during the period ended June 30, 2000.

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was  charged $5 pursuant to the
transfer agency agreement.


(B)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.

NOTE 3--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$1,569,545 and $1,392,150, respectively.

At  June  30,  2000,  accumulated net unrealized depreciation on investments was
$65,082, consisting of $154,067 gross unrealized appreciation and $219,149 gross
unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

                                                                  The Portfolio

                      Dreyfus Investment Portfolios, Emerging Leaders Portfolio

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Emerging  Leaders  Portfolio,  covering  the  six-month period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  portfolio  was managed during the reporting period, including a
discussion with the portfolio managers, Paul Kandel and Hilary Woods.

While  small-cap  stock  prices were ultimately little changed over the past six
months,  the  period was marked by high levels of volatility and dramatic shifts
in  investor sentiment. Between January and mid-March, both small- and large-cap
stocks  generally  continued  to  advance, led by fast-growing technology stocks
that,  many  investors  believed,  would  benefit  most  from the "new economy."
Subsequently,  however,  technology stocks corrected sharply over concerns about
rising  interest rates and extremely high valuations. Other sectors of the stock
market also declined, erasing most of the gains achieved earlier in the year.

Also,  primarily  because  of  the  precipitous drop in technology stock prices,
small-capitalization   stocks   generally   outperformed   large-cap   stocks,
particularly  in  the  value-oriented  segment  of the market, a reversal of the
trends  established  over  the past several years. In our view, these short-term
swings  in  investor  sentiment  highlight  once  again  the importance of broad
diversification and a long-term perspective for most investors.

We  appreciate  your confidence over the past six months, and we look forward to
your  continued participation in Dreyfus Investment Portfolios, Emerging Leaders
Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Paul Kandel and Hilary Woods, Portfolio Managers

How did Dreyfus Investment Portfolios, Emerging Leaders Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Emerging  Leaders  Portfolio produced a total return of 15.97%.(1) This compares
with  a  total  return  of 3.04% for the portfolio's benchmark, the Russell 2000
Index of small-capitalization stocks, for the same period.(2)

We  attribute  the  portfolio's strong performance to our success in identifying
attractive  individual  investment  opportunities among a wide range of sectors,
industries  and  investment  styles. The portfolio also succeeded in emphasizing
some  of  the market's strongest sectors and de-emphasizing some of the market's
weakest sectors.

What is the portfolio's investment approach?

The  portfolio  seeks  capital  growth  by  investing  in a diversified group of
small-cap companies with total market values of $1.5 billion or less at the time
of  purchase. We focus primarily on companies we believe are emerging leaders in
their  respective  industries.  The companies in which we invest offer products,
processes  or  services  that  we  believe  enhance  their  prospects for future
earnings  growth.  Using  fundamental research, we look for stocks with dominant
positions  in  major  product lines, sustained records of achievement and strong
balance  sheets.  We  also  base  investment decisions on the expected impact of
changes in a company's management or organizational structure.

Our  investment  approach  targets  growth-oriented stocks (those companies with
earnings   that   are  expected  to  grow  faster  than  the  overall  market),
value-oriented  stocks  (those  that appear underpriced according to a number of
financial   measurements)   and  stocks  that  exhibit  both  growth  and  value
characteristics.  We  typically  sell  a stock when the reasons for buying it no
longer  apply  or  when the company begins to show deteriorating fundamentals or
poor relative performance.

                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

What other factors influenced the portfolio's performance?

Volatile market conditions prevailed during the first six months of 2000. Strong
U.S.  economic  growth  generated concerns about prospects for rising inflation,
which  prompted the Federal Reserve Board to raise short-term interest rates. In
this  environment  of  uncertainty, the stock market rose and fell rapidly, with
both  growth-  and  value-oriented  stocks  advancing  and retreating at various
times.  Technology  emerged  as  the  strongest  sector  of the equities market,
although  prices  of  many  of  the  most  speculative technology stocks fell as
investors  emphasized  financial stability and profitability. Energy stocks also
climbed  higher,  boosted  by  rising prices for oil and natural gas. Many other
sectors  did not fare as well. In particular, consumer staples companies faced a
highly  competitive  global  environment  that limited their ability to increase
prices and curtailed profitability.

These  conditions affected our allocation of the portfolio's assets. We added to
our  position  in  technology,  a  move that generally increased returns despite
losses  among  a  few  of  our Internet-related holdings. Our best performers in
technology  were  largely concentrated among companies developing components and
systems  to  build  out  wireless  and data telecommunications networks, such as
NetOptix  and  TranSwitch.  We  also  emphasized the portfolio's position in the
energy  sector  relative  to  the benchmark, successfully capitalizing on rising
commodity  prices  through  investments  in  energy  exploration  and production
companies,  such  as  Ocean  Energy and Newpark Resources. On the other hand, we
limited  the portfolio's exposure to utilities, a sector that often suffers when
energy  prices  rise.  Although  the  utilities  component  of  the Russell 2000
performed  poorly,  the  utilities  in  which  we  invested, such as natural gas
distributor Kinder Morgan, generally proved to be strong performers.

The  portfolio's  weakest  performance  resided in the consumer staples sector,
which suffered from rising interest rates and the competitive pressures we noted
earlier.   Some   of   our   consumer-related  investments  were  also  hurt  by
company-specific  events.  For  example,  the stock of Insight Communications, a
technologically advanced Midwest cable television operator, fell when an
anticipated acquisition failed to materialize. Nevertheless, we continued to
hold our investment because we believed the company's fundamentals remained
strong.

What is the portfolio's current strategy?

As  of  the  end  of  the reporting period, we have reduced our exposure to most
types   of  cyclicals,  such  as  housing,  autos,  industrial  commodities  and
machinery,  in  light  of  lower  than expected employment and economic figures,
which  indicate  that  the  rate  of  the  U.S.  economic growth may be slowing.
Conversely,  we  have initiated positions in cyclicals which we feel may benefit
from a plateauing in energy prices.

We have also reduced our holdings in the technology and energy sectors, bringing
the  portfolio's  allocations  in  these sectors more in line with those of the
benchmark.  We  have replaced those holdings with consumer and financial stocks,
many  of  which  have  fallen  to  levels we consider attractive. We continue to
adhere  to  our  blended  growth-and-value  investment  strategy  in  seeking to
outperform the Russell 2000 Index.

to  March  22,  2000,  Premier  Mutual  Fund Services, Inc. was the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 160,062 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series' operations;  expenses, which are applicable to all series  are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted  accounting  principles,  which  may  require  the  use  of  management
estimates and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which such securities are primarily traded or at the last sales price on the
national securities market. Securities not listed on an exchange or the national
securities  market,  or  securities  for  which  there were no transactions, are
valued at the average of the most recent
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

bid  and asked prices, except for open short positions, where the asked price is
used for valuation purposes. Bid price is used when no asked price is available.
Securities  for  which  there are no such valuations are valued at fair value as
determined  in  good  faith  under  the  direction  of  the  Board  of Trustees.
Investments  denominated in foreign currencies are translated to U.S. dollars at
the prevailing rates of exchange.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable, amortization of discount on investments is recognized on the accrual
basis.  Under the terms of the custody agreement, the fund received net earnings
credits  of  $280  during the period ended June 30, 2000 based on available cash
balances  left  on  deposit. Income earned under this arrangement is included in
interest income.


(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain   are   normally  declared  and  paid  annually,  but  the  fund  may  make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  could be offset by capital loss
carryovers, if any, it is the policy of the fund not to distribute such gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee and Other Transactions  with Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .90 of 1% of the value of the
portfolio's  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000  to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent  that  the  portfolio's  aggregate annual expenses,
exclusive  of  taxes,  brokerage  fees, interest on borrowings and extraordinary
expenses, exceed an annual rate of 1.50% of the value of the portfolio's average
daily  net  assets.  The  expense  reimbursement,  pursuant  to the undertaking,
amounted to $15,193 during the period ended June 30, 2000.

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000, the fund was charged $5 pursuant to the transfer
agency agreement.

                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

The  portfolio  compensates  Mellon  under  a  custody  agreement  for providing
custodial services for the portfolio. During the period ended June 30, 2000, the
portfolio was charged $1,956 pursuant to the custody agreement.

(B)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received an additional 25% of such  compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.

NOTE 3--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$2,197,590 and $1,984,486 respectively.

At  June  30,  2000,  accumulated net unrealized appreciation on investments was
$450,931, consisting of $543,727 gross unrealized appreciation and $92,796 gross
unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus Investment
Portfolios,  Founders  Discovery  Portfolio,  covering the six-month period from
January  1, 2000 through June 30, 2000. Inside, you'll find valuable information
about  how  the  portfolio  was managed during the reporting period, including a
discussion   with  its  portfolio  manager,  Robert  Ammann  of  Founders  Asset
Management LLC, the portfolio's sub-investment adviser.

While  small-cap  stock  prices were ultimately little changed over the past six
months,  the  period was marked by high levels of volatility and dramatic shifts
in  investor sentiment. Between January and mid-March, both small- and large-cap
stocks  generally  continued  to  advance, led by fast-growing technology stocks
that,  many  investors  believed,  would  benefit  most  from the "new economy."
Subsequently,  however,  technology stocks corrected sharply over concerns about
rising  interest rates and extremely high valuations. Other sectors of the stock
market also declined, erasing most of the gains achieved earlier in the year.

Also,  primarily  because  of  the  precipitous drop in technology stock prices,
small-capitalization   stocks   generally   outperformed   large-cap   stocks,
particularly  in  the  value-oriented  segment  of the market, a reversal of the
trends  established  over  the past several years. In our view, these short-term
swings  in  investor  sentiment  highlight  once  again  the importance of broad
diversification and a long-term perspective for most investors.

We  appreciate  your confidence over the past six months, and we look forward to
your   continued   participation  in  Dreyfus  Investment  Portfolios,  Founders
Discovery Portfolio.

Sincerely,


Stephen E. Canter

President and Chief Investment Officer

The Dreyfus Corporation

DISCUSSION OF PERFORMANCE

Robert Ammann, Portfolio Manager Founders Asset Management LLC, Sub-Investment
Adviser

How did Dreyfus Investment Portfolios, Founders Discovery Portfolio perform
relative to its benchmark?

For  the  six-month  period  ended June 30, 2000, Dreyfus Investment Portfolios,
Founders Discovery Portfolio produced a total return of 18.33%.(1) This compares
with  the 3.04% total return provided by the Russell 2000 Index, the portfolio's
benchmark, for the same period.(2)

We  attribute  the  portfolio's  strong gains during the past six months to our
individual  stock  selection  strategy in a difficult investment environment. We
found  opportunities in a wide variety of small-cap companies, representing many
different  industries,  which  have demonstrated an ability to provide long-term
earnings growth.

What is the portfolio's investment approach?

The  portfolio  invests  primarily  in equity securities of small and relatively
unknown  U.S.-based  companies  that  we  believe possess high growth potential.
Typically,  these companies are not listed on national securities exchanges, but
instead  trade  on the over-the-counter market. The portfolio may also invest in
larger companies if, in our opinion, they represent better prospects for capital
appreciation.  Although  the  portfolio will normally invest in common stocks of
U.S.-based  companies,  it  may  invest up to 30% of its total assets in foreign
securities.

Rather  than utilizing a "top-down" approach to stock selection, which relies on
forecasting  stock  market  trends, we focus on a "bottom-up" approach, in which
stocks  are  chosen according to their own individual merits. Stock selection is
made  on  a company-by-company basis, with particular emphasis on companies that
we  believe  are  well-managed  and  well-positioned  within  their  industries.

                                                                   The Portfolio


DISCUSSION OF PERFORMANCE (CONTINUED)

What other factors influenced the portfolio's performance?

The  six-month  reporting  period  was  marked  by  high  levels of stock market
volatility  and  changing investor preferences in three areas: technology versus
non-technology  industry groups; small-cap versus mid- and large-cap stocks; and
growth- versus value- investment styles.

From  the  beginning  of  the year through mid-March 2000, the U.S. stock market
advanced sharply, driven primarily by strong gains within the technology sector.
During  this  period, the prices of many high-flying technology stocks continued
to  climb,  especially  those  stocks  that were related to the "new economy" of
Internet-related   products  and  services.  In  addition,  small-cap  companies
generally  produced  higher  returns  than  their large-cap counterparts and the
growth   style   of  investing  outperformed  the  value  style  of  investing.

By  mid-March,  however,  those trends had generally begun to reverse themselves
when  many technology stocks fell out of favor. Even during this downturn in the
technology  sector  as  a  whole,  there  were  days when individual tech stocks
bounced  back,  which  increased  the  stock market's volatility levels. In this
environment,  which  lasted  through  the end of May, large-cap stocks generally
produced  higher returns than small-cap stocks, and the value style of investing
provided  better  returns  than  the  growth  style  of  investing.  In  such an
environment,  the  portfolio's  strong  performance  was  primarily  due to its
holdings  in  the technology and health care sectors. In June, technology stocks
once  again  began  to rebound, small-cap stocks performed better than large-cap
stocks,  and  growth-style  investing  outperformed  the  value-style  investing
approach.

Within   the   technology  area,  which  was  the  portfolio's  largest  sector
concentration  during  the  period, we saw strong returns from semiconductor and
telecom  equipment companies. A notable example is Brooks Automation, a supplier
of  tool  and factory hardware and software automation solutions, which provided
strong returns early in the period. In addition, Digital Microwave, currently a
top 10 holding in the portfolio, benefited from the development of "broadband
fixed wireless," which enables voice and data to be transmitted and received
without the costly need to lay fiber optic cable.

What is the portfolio's current strategy?

We  are  maintaining  our  bottom-up  strategy of selecting stocks one at a time
based  on  their  own  individual  merits.  Accordingly,  and in response to the
challenging market environment, we have recently been increasing our emphasis on
those  stocks  in which we have the most confidence because we believe they have
strong  growth  potential.  This has led to a continued decline in the number of
stocks  held  in  the  portfolio,  as well as some modest increases in portfolio
concentration  among  the portfolio's top holdings. As of June 30, 2000, the top
10   holdings   comprised   approximately   21%  of  the  portfolio's  assets.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus  Investment  Portfolios  (the "fund") is registered under the Investment
Company  Act  of  1940,  as  amended  (the  "Act" ), as  an  open-end management
investment  company,  operating  as  a  series company currently offering twelve
series,  including  the  Founders  Discovery  Portfolio  (the  "portfolio"). The
portfolio  is  only  offered  to  separate  accounts  established  by  insurance
companies  to  fund  variable  annuity  contracts  and  variable  life insurance
policies.  The  portfolio  is  a  diversified series. The portfolio's investment
objective is capital appreciation. The Dreyfus Corporation ("Dreyfus") serves as
the  portfolio's  investment  adviser. Dreyfus is a direct subsidiary of Mellon
Bank,  N.A.  ("Mellon"), which is a wholly-owned subsidiary of  Mellon Financial
Corporation.   Founders   Asset  Management  LLC  ("Founders") serves  as  the
portfolio's  sub-investment  adviser.  Founders  is  a  90%-owned subsidiary of
Mellon.  Effective  March  22,  2000,  Dreyfus  Service  Corporation  ("DSC") a
wholly-owned  subsidiary  of  Dreyfus, became the distributor of the portfolio's
shares,  which are sold to the public without a sales charge. Prior to March 22,
2000, Premier Mutual Fund Services, Inc. was the distributor.

As  of  June  30,  2000, MBC Investments Corp., an indirect subsidiary of Mellon
Financial Corporation, held 160,554 shares of the portfolio.

The  fund accounts separately for the assets, liabilities and operations of each
series.  Expenses  directly  attributable  to  each  series  are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

The  portfolio's financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(A)  PORTFOLIO  VALUATION:  Investments  in  securities  (including  options and
financial futures) are valued at the last sales price on the securities exchange
on  which  such  securities  are  primarily traded or at the last
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

sales  price  on  the  national  securities  market. Securities not listed on an
exchange  or  the national securities market, or securities for which there were
no  transactions,  are  valued  at  the average of the most recent bid and asked
prices. Bid price is used when no asked price is available. Securities for which
there  are  no  such  valuations  are valued at fair value as determined in good
faith  under  the direction of the Board of Trustees. Investments denominated in
foreign  currencies  are  translated  to U.S. dollars at the prevailing rates of
exchange. Forward currency exchange contracts are valued at the forward rate.

(B)  FOREIGN  CURRENCY TRANSACTIONS: The portfolio does not isolate that portion
of the results of operations resulting from changes in foreign exchange rates on
investments  from  the  fluctuations  arising  from  changes in market prices of
securities  held.  Such  fluctuations  are  included  with  the net realized and
unrealized gain or loss from investments.

Net realized foreign exchange gains or losses arise from sales and maturities of
short-term  securities,  sales  of  foreign currencies, currency gains or losses
realized  on  securities  transactions and the difference between the amounts of
dividends,  interest  and  foreign withholding taxes recorded on the portfolio's
books  and  the U.S. dollar equivalent of the amounts actually received or paid.
Net  unrealized foreign exchange gains or losses arise from changes in the value
of  assets  and  liabilities other than investments in securities resulting from
changes  in exchange rates. Such gains and losses are included with net realized
and unrealized gain or loss on investments.

(C)  SECURITIES  TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Dividend income is
recognized  on  the  ex-dividend  date  and  interest  income,  including, where
applicable,  amortization  of  discount  on  investments,  is  recognized on the
accrual  basis. Under the terms of the custody agreement, the portfolio received
net  earnings  credits  of $1,661 during the period ended June 30, 2000 based on
available cash balances left on deposit. Income earned under this arrangement is
included in interest income.

(D)  DIVIDENDS  TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends  from  investment  income-net  and dividends from net realized capital
gain  are  normally  declared  and  paid  annually,  but  the portfolio may make
distributions  on  a  more  frequent  basis  to  comply  with  the  distribution
requirements  of  the Internal Revenue Code of 1986, as amended (the "Code"). To
the  extent  that  net  realized  capital  gain  can  be  offset by capital loss
carryovers,  if  any,  it  is the policy of the portfolio not to distribute such
gain.

(E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the portfolio to continue to
qualify  as a regulated investment company, if such qualification is in the best
interests  of  its  shareholders, by complying with the applicable provisions of
the  Code,  and to make distributions of taxable income sufficient to relieve it
from substantially all Federal income and excise taxes.

NOTE 2--Investment Advisory Fee, Sub-Investment Advisory Fee and Other
Transactions With Affiliates:

(A)  Pursuant  to  an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .90 of 1% of the value of the
portfolio' s  average  daily  net  assets  and  is  payable monthly. Dreyfus has
undertaken  from  January  1,  2000  through  December  31,  2000, to reduce the
investment  advisory  fee  and  reimburse  such  excess  expenses  paid  by  the
portfolio,  to  the  extent that the portfolio's aggregate expenses exclusive of
taxes, brokerage fees, interest on borrowings and extraordinary expenses, exceed
an  annual  rate  of  1.50%  of  the  value of the portfolio's average daily net
assets.  The  expense  reimbursement,  pursuant  to the undertaking, amounted to
$31,375 during the period ended June 30, 2000.

Pursuant   to   a   Sub-Investment   Advisory   Agreement   with  Founders,  the
sub-investment advisory fee is payable monthly by Dreyfus, and is
                                                                   The Portfolio

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

based  upon  the  value of the portfolio's average daily net assets, computed at
the following annual rates:

          AVERAGE NET ASSETS
          ------------------------

          0 to $100 million. . . . . . . . . . . . . . . . .      .25 of 1%

          In excess of $100 million to $1 billion. . . . . .      .20 of 1%

          In excess of $1 billion to $1.5 billion. . . . . .      .16 of 1%

          In excess of $1.5 billion. . . . . . . . . . . . .      .10 of 1%

The  portfolio  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform  transfer  agency services for the portfolio. During the
period  ended  June  30,  2000,  the  portfolio  was  charged $5 pursuant to the
transfer agency agreement.

The  portfolio  compensates  Mellon  under  a  custody  agreement  for providing
custodial services for the portfolio. During the period ended June 30, 2000, the
portfolio   was   charged   $13,266   pursuant   to   the   custody  agreement.

(B)  Each  Board  member also serves as a Board member of other funds within the
Dreyfus complex (collectively, the "Fund Group"). Effective April 13, 2000, each
Board member who is not an "affiliated person" as defined in the Act receives an
annual fee of $25,000 and an attendance fee of $4,000 for each in person meeting
and $500 for telephone meetings. These fees are allocated among the funds in the
Fund  Group.  The  Chairman  of  the  Board  receives  an additional 25% of such
compensation.  Prior  to  April  13,  2000,  each  Board  member  who was not an
"affiliated  person" as defined in the Act received from the fund an annual fee
of  $1,000  and an attendance fee of $250 per meeting. The Chairman of the Board
received  an additional 25% of such compensation. Subject to the fund's Emeritus
Program  Guidelines,  Emeritus  Board members, if any, receive 50% of the fund's
annual  retainer  fee  and  per  meeting  fee  paid at the time the Board member
achieves emeritus status.


NOTE 3--Securities Transactions:

The  aggregate amount of purchases and sales of investment securities, excluding
short-term  securities,  during  the  period  ended  June  30, 2000, amounted to
$4,868,640 and $1,806,950, respectively.

At  June  30,  2000,  accumulated net unrealized appreciation on investments was
$753,820,  consisting  of  $884,376  gross  unrealized appreciation and $130,556
gross unrealized depreciation.

At  June  30,  2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

                                                                   The Portfolio
