LETTER TO SHAREHOLDERS

Dear Shareholder:

We are pleased to provide you with this report on the Dreyfus New York Insured
Tax  Exempt  Bond  Fund  for the six-month reporting period ended June 30, 1998.
Your  Fund  produced  a total return, including share price changes and dividend
income  generated,  of  1.98%,* and an annualized tax-free distribution rate per
share of 4.32%.**

Economic Review

In recent testimony to Congress, Federal Reserve Board Chairman Alan Greenspan
proclaimed  the  economy  to be "as impressive as any I have witnessed." Indeed,
the  performance of the economy has been tremendous, with solid, noninflationary
economic  growth  and  a  robust  rate  of  new  job  creation. Accordingly, the
unemployment  rate hovers near its 28-year low. Not surprisingly, consumers brim
with confidence: new home sales were recently at record levels, and retail sales
have  surged  since January. The enthusiastic spending of consumers has, so far,
offset  the  adverse  effects  of  the  economic  problems in Asia. In fact, the
financial  crisis  in  the  Far East has proved a boon to consumers, since lower
import  prices  have  further  subdued  domestic price pressures and helped keep
interest  rates  low.  Remarkably,  despite  the strengthening economy since the
beginning  of  this  year,  inflation  has  waned  further. With inflation under
control  and  the  economy  just  beginning to experience a reduction in foreign
demand, the Federal Reserve Board has been reluctant to raise interest rates for
fear of further roiling Asian financial markets. The last increase in short-term
rates  came  in  March 1997 when the Federal Reserve Board Open Market Committee
(the policy-making arm of The Federal Reserve) hiked the target rate for Federal
Funds by one quarter of a percent to 5.5%.

  Even  with  the  booming  job  market, wage gains have had little inflationary
effect,  since business spending in productivity-enhancing capital equipment has
been  strong  throughout  the  economic  expansion. The one soft spot in the job
market  has  been  in manufacturing: industrial production has slowed -- a clear
sign that Asian economic woes are being felt here -- and inventories of domestic
manufacturers  have  risen due to the reduction in foreign demand. Many analysts
expect that the growing trade deficit will retard second-quarter economic growth
and  possibly  serve  as  a  drag over the foreseeable future. This reduction in
foreign  demand  could  further  moderate  the  rate  of domestic production and
consequently  ease  the  demand  for labor, thus lessening inflationary pressure
resulting  from  wage  increases. Cheaper imports have also weakened the pricing
environment  for  U.S. manufacturers and, in consequence, acted as an additional
curb  to inflation. All this has been part of what Chairman Greenspan called our
economy' s "virtuous cycle" where even so-called crises have proven economically
beneficial. As a further example, the economic upheavals in Asia and Russia have
caused nervous foreign investors to seek refuge in the U.S. bond market, causing
a  demand  surge that has helped maintain our low interest rate environment. Yet
we,  along  with  Chairman Greenspan, are skeptical that our economy has somehow
moved   "beyond  history,"  and  we  share  his  vigilance  regarding  signs  of
inflationary imbalances.

Market Environment

The market environment for bonds has been supportive. Since our last report to
shareholders,  yields on long-term, high-grade tax-exempt bonds have been almost
unchanged,  whereas U.S. Treasury bond yields have fallen by over one-quarter of
a  percent.  Certainly,  it has been the uncertain impact of the spreading Asian
financial  crisis that has kept the Fed from pushing rates higher despite strong
domestic  economic  data.  Spurred by this benign interest rate environment, the
issuance  of new municipal securities surged during the period, as a near record
$146 billion of debt came to market.

  We  believe  that  it is still too early to draw any conclusions regarding how
much  the  expanding  Asian crisis will impact the U.S. economy. Until a clearer
picture emerges from Asia and Russia, we believe investors will continue to find
fixed-income  investments  attractive.  The  still  strong and expanding economy
would  normally  be  a  cause  for  concern  to inflation watchers. However, the
general  belief  is  that  the  Fed  will  refrain from taking any interest rate
actions  that  could  exacerbate the problems in these troubled countries. While
the  most  recent  economic  and  employment data has been indicative of a still
robust economy, inflation remains quiescent.

  The  fixed-income  markets  have  now  weathered  the period of seasonal price
weakness  that results from large debt issuance. Traditionally, as summer wanes,
the pressure from too much new-issue supply begins to abate. Given this fact and
the  reasons  cited  above,  we believe that the current environment supports an
outlook  for steady monetary policy and well-anchored interest rates. As long as
inflation  growth remains low, we don't anticipate the Fed reacting to potential
strong  employment  and economic data by raising rates. Instead, we believe that
the   events  in  Asia,  Russia  and  other  emerging  countries  will  be  more
influential.

Portfolio Overview

  As  discussed  above,  municipal  bond  prices  have experienced little change
during  the  past  six  months.  Because  of  this  decreased volatility, income
generated  from  the  Fund' s portfolio of tax-exempt bonds has been the primary
factor  in performance determination. Interestingly, despite the general decline
in  taxable  bond  interest  rates, tax-exempts have not kept pace. Mindful that
interest  rates  have fallen precipitously in recent years, we continue with our
management  approach. We continue to strive to generate a competitive tax-exempt
yield  while  maintaining  a  neutral  portfolio posture toward the direction of
interest rates. The Fund's duration measure is being maintained at approximately
seven years, which we believe to be market neutral.

  The  New  York investor was clearly the beneficiary of the large volume of new
issuance  over the past six months. The most significant of these issues was the
$3  billion  loan for the Long Island Power Authority. The success of this issue
(the  largest  tax-exempt deal in history) underscores the underlying demand for
municipal  bonds. Aiding the overall stature of New York debt is the improvement
in  both  the  State's and New York City's economies, resulting in credit rating
upgrades  for  both.  This  has translated into lower interest costs on new debt
issuance.

  Looking  forward,  our  focus  will  continue  to  be  on  owning  the optimal
securities  meeting  our  investment criteria. The municipal market has not made
any  significant  moves  in recent weeks. It is likely that this condition could
persist  going  forward  until a clearer picture of the Asian impact emerges. In
the  meantime,  we continue to mine for those investment opportunities that meet
our  investment  criteria  and will add incremental yield and performance to the
Fund.

               Very truly yours,



               [Richard J. Moynihan, signature logo]

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

Dreyfus New York Insured Tax Exempt Bond Fund (the "Fund") is registered under
the  Investment  Company  Act  of  1940  (" Act" ) as a non-diversified open-end
management  investment  company.  The  Fund's investment objective is to provide
investors  with  as high a level of current income exempt from Federal, New York
State  and  New York City income taxes as is consistent with the preservation of
capital.  The  Dreyfus  Corporation  ("Manager") serves as the Fund's investment
adviser.  The Manager is a direct subsidiary of Mellon Bank, N.A. Premier Mutual
Fund Services, Inc. (the "Distributor") is the distributor of the Fund's shares,
which are sold to the public without a sales load.

  The  Fund' 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 options and
financial  futures  on  municipal  and U.S. treasury securities) 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 portfolio securities) are carried at fair
value as determined by the Service, based on methods which include consideration
of:  yields  or  prices  of  municipal securities of comparable quality, coupon,
maturity  and  type;  indications  as to values from dealers; and general market
conditions.  Options  and  financial  futures  on  municipal  and  U.S. treasury
securities  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. Investments 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.

(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,
adjusted   for   amortization  of  premiums  and  original  issue  discounts  on
investments, is earned from settlement date and recognized on the accrual basis.
Securities  purchased  or sold on a when-issued or delayed-delivery basis may be
settled  a  month or more after the trade date. Under the terms of the custodian
agreement,  the  Fund  received  net earnings credit of $3,688 during the period
ended  June  30,  1998  based on available cash balances left on deposit. Income
earned under this arrangement is included in interest income.

  The  Fund  follows  an  investment  policy of investing primarily in municipal
obligations  of  one  state. Economic changes affecting the state and certain of
its  public  bodies  and municipalities may affect the ability of issuers within
the  state to pay interest on, or repay principal of, municipal obligations held
by the Fund.

  (C)  DIVIDENDS  TO  SHAREHOLDERS:  It  is  the  policy  of the Fund to declare
dividends  daily  from  investment  income-net. Such dividends are paid monthly.
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. To the extent
that net realized capital gain can be offset by capital loss carryovers, if any,
it is the policy of the Fund not to distribute such gain.

  (D)  FEDERAL INCOME TAXES: It is the policy of the Fund to continue to qualify
as a regulated investment company, which can distribute tax exempt dividends, by
complying  with  the  applicable provisions of the Internal Revenue Code, and to
make distributions of income and net realized capital gain sufficient to relieve
it from substantially all Federal income and excise taxes.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

NOTE 2--BANK LINE OF CREDIT:

  The  Fund  participates  with  other  Dreyfus-managed  funds in a $600 million
redemption  credit  facility  (" Facility" ) to  be  utilized  for  temporary or
emergency  purposes,  including  the  financing  of  redemptions.  In connection
therewith, the Fund has agreed to pay commitment fees on its pro rata portion of
the  Facility.  Interest  is  charged  to  the Fund at rates based on prevailing
market  rates  in effect at the time of borrowings. During the period ended June
30, 1998, the Fund did not borrow under the Facility.

NOTE 3--MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

  (A)  Pursuant  to  a  management agreement ("Agreement") with the Manager, the
management  fee  is computed at the annual rate of .60 of 1% of the value of the
Fund' s  average daily net assets and is payable monthly. The Agreement provides
that if in any full fiscal year the aggregate expenses of the Fund, exclusive of
taxes,  brokerage,  commitment  fees,  interest  on borrowings and extraordinary
expenses,  exceed 11_2% of the value of the Fund's average daily net assets, the
Fund  may  deduct  from  payments to be made to the Manager, or the Manager will
bear  such  excess  expense. During the period ended June 30, 1998, there was no
expense reimbursement pursuant to the Agreement.

  (B)  Under  the Service Plan (the "Plan") adopted pursuant to Rule 12b-1 under
the Act, the Fund (a) reimburses the Distributor for payments to certain Service
Agents   (a   securities   dealer,   financial  institution  or  other  industry
professional)  for  distributing  the  Fund' s  shares and servicing shareholder
accounts  ("Servicing") and (b) pays the Manager, Dreyfus Service Corporation, a
wholly-owned  subsidiary  of  the  Manager,  or  any  affiliate (collectively, "
Dreyfus" ) for  advertising and marketing relating to the Fund and Servicing, at
an  aggregate  annual rate of .25 of 1% of the value of the Fund's average daily
net  assets.  Both  the  Distributor and Dreyfus may pay Service Agents a fee in
respect  of  the Fund's shares owned by shareholders with whom the Service Agent
has  a  Servicing  relationship  or  for whom the Service Agent is the dealer or
holder  of  record. Both the Distributor and Dreyfus determine the amounts to be
paid  to  Service  Agents  to which it will make payments and the basis on which
such  payments  are made. The Plan also separately provides for the Fund to bear
the  costs  of  preparing,  printing  and  distributing  certain  of  the Fund's
prospectuses  and statements of additional information and costs associated with
implementing  and  operating  the Plan, not to exceed the greater of $100,000 or
 . 005  of  1%  of  the value of the Fund's average daily net assets for any full
year.  During  the  period ended June 30, 1998, $160,725 was charged to the Fund
pursuant to the Plan, of which $483 was reimbursed by the Manager.

  The  Fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the
Manager,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform transfer agency services for the Fund. During the period
ended  June  30,  1998,  the  Fund  was charged $22,987 pursuant to the transfer
agency    agreement.

  (C)  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 and the Trustee Emeritus receives 50% of such compensation.

  (D)  A  1%  redemption  fee  is  charged  and  retained by the Fund on certain
redemptions  of  Fund  shares (including redemptions through the use of the Fund
Exchanges  service)  where the shares being redeemed were issued subsequent to a
specified effective date and the redemption or exchange occurs less than fifteen
days following the date of issuance.

NOTE 4--SECURITIES TRANSACTIONS:

  The  aggregate  amount  of  purchases  and  sales  of  investment  securities,
excluding  short-term securities, during the period ended June 30, 1998 amounted
to $23,589,089 and $34,532,112, respectively.

  At  June  30, 1998, accumulated net unrealized appreciation on investments was
$6,559,796,  consisting  of $6,621,625 gross unrealized appreciation and $61,829
gross unrealized depreciation.

  At  June 30, 1998, 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).
