LETTER TO SHAREHOLDERS

Dear    Shareholder:

  We  are  pleased to report the performance for the Dreyfus Variable Investment
Fund  --  Quality  Bond Portfolio. For the six-month reporting period ended June
30,  1998,  the  Portfolio produced a total return including share price changes
and dividend income generated of 4.12%,* compared to 4.02% for the Merrill Lynch
Domestic  Master  Index  (Subindex  D010) .**  Income  dividends  paid  from net
investment  income  during the period amounted to $0.353 per share, representing
an annualized distribution rate per share of 5.98%.***

ECONOMIC REVIEW

  In  the first half of 1998, three main regions of the world had very different
economic fundamentals. The U.S. entered the year with a strong economy near full
employment, with unemployment only slightly above 4%. The tight labor market led
the  Federal Reserve Board to contemplate a rise in interest rates, but the U.S.
economy cooled enough over the course of the half-year that no action was taken.
After  many  years  of  subpar  economic growth, continental Europe moved into a
better  economic  expansion.  Unlike  the  U.S.,  Europe  has substantial excess
capacity  of  productive plant and labor. In Asia, weak economies were pervasive
in the aftermath of the Asian financial crisis late last year.

  A  main  influence  on  the  U.S.  economy in the first half of 1998 was Asian
economic  weakness.  It  had  both  positive  and negative effects. The positive
effects  hit  first.  Actual inflation and expected inflation dropped, causing a
decline in long-term Treasury bond yields and mortgage rates. This caused a boom
in housing and rising asset prices, including bonds, stocks and houses. The fall
in inflation helped the consumer sector as more of the growth in consumer income
was  left  over  after  inflation to buy goods and services. Consumers benefited
from  a  combination  of  good  growth in income after inflation, a strong labor
market and rising prices of assets they owned.

  The  negative  effect  of  Asian  weakness was directed towards the industrial
sector  rather  than the consumer sector. By midyear, the evidence of industrial
weakness  was  clear-cut  in response to a slowing of inventory accumulation and
weakened  exports. One result of this industrial weakness was to cool off a U.S.
economy  that had been growing so rapidly that there were fears that the Federal
Reserve  might  raise interest rates. This favorable shift in expectations about
Fed  policy  was  one reason for the rise in U.S. bond and stock prices. Another
background factor was the increasing evidence of prospects for multi-year budget
surpluses    in    the    U.S.

MARKET ENVIRONMENT

  The  bond  market  has  been  very  strong  from  a fundamental point of view.
Everything  from  reduced  supply of U.S. Treasury debt, to the Asian crisis, to
falling commodity prices have worked in the bond market's favor.

  At  the  time  of this letter, it is very hard to find any sentiment regarding
the  bond  market that is not bullish. Generally, there are several themes which
have  produced  this  optimism  in  the bond market. The first is that Japan may
never  put  forth a credible financial package, which is a key element to ending
the  Asian  crisis.  Second,  OPEC  members  may  never  actually  adhere to any
agreed-upon  cutbacks  in  oil  production,  which  should  keep oil prices from
rising.  Also, many believe yields are considered too high on a global basis. On
the  domestic  front,  inflation  generally  is  viewed as nonexistent. And, the
manufacturing sector of the U.S. economy is already signaling much slower growth
ahead.

  The  30-year  Treasury  bond  traded  in  a  range of 5.5% to 5.85% during the
reporting  period.  Currently,  the yield is at the lower end of that range. The
above-mentioned themes have been talked about enough that one can assume that at
the  moment  they  are  priced into yield levels and could cause yields to drop

  When  viewing the above bond market themes, you can see that they are somewhat
intertwined.  If  one  of  them  were to change, the others could be impacted as
well.  The Japanese fiscal reform or policy change could have the biggest impact
on  the  direction  of  the  others.  While  we  believe  it will take years for
recoveries  to  be  in place for Asia, the direction is important. If the fiscal
package  from  Japan is credible and sizable, the financial markets may begin to
assume  that the worst is behind. This could in turn positively impact commodity
prices  as  people anticipate a greater need in the future. The "zero inflation"
scenario  could  be  hindered  by  any  rise  in commodity prices. In fact, core
inflation  in  the U.S. has been moving up. If it were not for the Asian crisis'
impact  on commodity prices, it is likely that fewer people would be proclaiming
that    inflation    is    dead.

While only time will tell what will occur, the external pressure being exerted
on  Japan  to  reform seems great by any historical standards. It is our opinion
that  Japan may reform sooner than the markets are anticipating (albeit it could
take years to work through), but we are less convinced about the prediction that
rates  will  fall  precipitously  further without more defining news on the bond
market themes discussed above.

PORTFOLIO OVERVIEW

  In  light  of our apprehension for a continued bond market rally, we currently
believe  that  a  neutral  stance  in  duration  is warranted. Going forward, we
anticipate  that  the target duration will be in the area of 4.5 years. Over the
last  6  months ended June 30, 1998 the duration of the Fund has been as high as
5.0 years, which worked out well as rates declined over that time. Of course, we
will have to see what develops and our approach is subject to change.

  During  the  reporting  period,  we  positioned  the Fund in an effort to take
advantage  of a flatter yield curve, which worked well. However, we believe that
positioning  the  Fund  for  a  steepening yield curve might be warranted in the
future.  The  reasons  for  this are twofold. First, if inflation picks up, even
minimally, 30-year Treasury bonds should underperform. (Inflation would eat away
at  longer  maturities.)  Or, if the economy really does slow down, we currently
believe  that  the  Fed  would  remove  their  tightening bias, which could help
shorter  maturity securities. Second, in economic slowdowns banks generally have
tended  to  invest  capital  because  loan  demand slows. This could mean better
buying of shorter dated securities.

  We  have  allocated  resources  to  "Treasury  Inflation Protected Securities"
(TIPS). TIPS represent value on a very simple basis: As of June 30, 1998 30-year
Treasury  bonds yielded 5.63%, and 30-year TIPS yielded 3.65%. Based on the rate
of  inflation as of June 30, 1998, we believe that TIPS provided better relative
value  as compared to 30-year Treasury bonds. We had a position of approximately
8% in this product as of June 30, 1998.

  The  corporate  security strategy has been to emphasize quality and liquidity.
The  credit cycle was about as good as a bond investor could wish for during the
reporting period. The spread (the yield difference) between corporate securities
and  Treasuries  was  historically  narrow.  This  spread had been narrowing for
several years in coordination with improving company cash flows. In light of the
global crisis, particularly in Asia, we believe that corporate earnings may have
hit the peak of this cycle.

               Very truly yours,

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

  Dreyfus  Variable  Investment  Fund  (the  "Fund" ) is  registered  under  the
Investment  Company  Act  of  1940  ("Act") as an open-end management investment
company,  operating  as  a  series  company  currently offering thirteen series,
including  the  Quality  Bond  Portfolio  (the "Series") and is intended to be a
funding  vehicle  for  variable  annuity  contracts  and variable life insurance
policies to be offered by the separate accounts of life insurance companies. The
Series  is  a  diversified  portfolio.  The  Series'  investment objective is to
provide  the  maximum amount of current income to the extent consistent with the
preservation   of   capital  and  the  maintenance  of  liquidity.  The  Dreyfus
Corporation  (" Dreyfus") serves as the Series' investment adviser. Dreyfus is a
direct subsidiary of Mellon Bank, N.A. ("Mellon"). Premier Mutual Fund Services,
Inc.  is  the  distributor of the Series' shares, which are sold without a sales
charge.

  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  Series'  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) 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  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 portfolios' 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.
Short-term  investments, excluding U.S. Treasury Bills, are carried at amortized
cost, which approximates value.

(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.  Interest income,
including,  where  applicable,  amortization  of  discount  on  investments,  is
recognized on the accrual basis. Under the terms of the custodian agreement, the
Series  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 are normally declared and paid annually, but the
Series  may  make  distributions  on  a  more  frequent basis to comply with the
distribution  requirements  of the Internal Revenue Code. To the extent that net
realized  capital  gain  can be offset by capital loss carryovers, if any, it is
the policy of the Series not to distribute such gain.

  (D)  FEDERAL  INCOME  TAXES:  It  is  the  policy of the Series 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  Internal  Revenue  Code,  and  to  make  distributions  of  taxable  income
sufficient to relieve it from substantially all Federal income and excise taxes

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

NOTE 2--BANK LINES OF CREDIT:

  The  Series  may  borrow  up  to  $10  million for leveraging purposes under a
short-term  unsecured line of credit and 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  Series at rates which are related to the Federal
Funds rate in effect at the time of borrowings. During the period ended June 30,
1998 the Series did not borrow under either 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 .65 of 1% of the value of the
Series' average daily net assets and is payable monthly.

  The  Series  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 Series.

  The  Series  compensates  Mellon  under  a  custody  agreement  for  providing
custodial  services  for  the Series. During the period ended June 30, 1998, the
Series was charged $8,039 pursuant to the custody agreement.

  (B)  Each  trustee  who  is  not  an "affiliated person" as defined in the Act
receives from the Fund an annual fee of $2,500 and an attendance fee of $250 per
meeting.  The  Chairman  of  the  Board  receives  an  additional  25%  of  such
compensation.

NOTE 4--SECURITIES TRANSACTIONS:

The aggregate amount of purchases and sales (including paydowns) of investment
securities,  excluding  short-term  securities, during the period ended June 30,
1998, amounted to $136,325,885 and $137,805,534, respectively.

  At  June  30, 1998, accumulated net unrealized appreciation on investments was
