LETTER FROM THE CHAIRMAN

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Insured Municipal Bond Fund, Inc., covering the 12-month period from May 1, 2005, through April 30, 2006.

Since June 2004, the Federal Reserve Board (the "Fed") has attempted to manage U.S. economic growth and forestall potential inflation by gradually raising short-term interest rates. Recently, Fed Chairman Ben Bernanke suggested that the Fed may soon pause to assess current economic data and evaluate the impact of its credit tightening campaign. In our view, the Fed's efforts so far have largely been successful: the economy has grown at a moderate pace, the unemployment rate has dropped to multi-year lows, corporate profits have risen, and inflation has remained low despite volatile energy prices.

However, the municipal bond market is more likely to be influenced not by what the Fed already has accomplished, but by investors' expectations of what is to come, including the Fed's decision to increase interest rates further, maintain them at current levels or reduce them to stimulate future growth.We believe that this decision will depend largely on the outlook for core inflation in 2007. The Fed probably can stand pat as long as it expects inflation to remain subdued. But if inflationary pressures build in an expanding economy, the Fed may choose to resume tightening later this year.As always, we urge you to discuss with your financial advisor the potential implications of these possibilities on your investments.

For information about how the fund performed, as well as market perspectives, we have provided a Discussion of Fund Performance given by the fund's portfolio manager.

Thank you for your continued confidence and support.

Sincerely,

  Stephen E. Canter
Chairman and Chief Executive Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

Scott Sprauer, Portfolio Manager

How did Dreyfus Insured Municipal Bond Fund, Inc. perform relative to its benchmark?

For the 12-month period ended April 30, 2006, the fund achieved a total return of 1.53% .1 In comparison, the Lehman Brothers Municipal Bond Index (the "Index"), the fund's benchmark index, achieved a total return of 2.16% for the same period.2 In addition, the fund is reported in the Lipper Insured Municipal Debt Funds category, and the average total return for all funds reported in the category was 1.30% for the reporting period.3

Despite rising interest rates in a growing economy, municipal bond prices held up relatively well over the reporting period due to low inflation and robust investor demand for a more limited supply of newly issued securities. The fund produced a return that was better than its Lipper category average. However, the fund underperformed its benchmark, which contains bonds with a variety of credit profiles, not just insured securities, and does not reflect fund fees and expenses.

What is the fund's investment approach?

The fund seeks as high a level of current income exempt from federal income tax as is consistent with the preservation of capital.To pursue this goal, the fund normally invests substantially all of its assets in investment-grade municipal bonds that provide income exempt from federal personal income tax. These bonds will be insured as to the timely payment of principal and interest by recognized insurers of municipal bonds.4 The dollar-weighted average maturity of the fund's portfolio normally exceeds 10 years, but the fund is not subject to any maturity restrictions.

We may buy and sell bonds based on credit quality, market outlook and yield potential. In selecting municipal bonds for investment, we may assess the current interest-rate environment and a municipal bond's

DISCUSSION OF FUND PERFORMANCE (continued)

potential volatility in different rate environments. We focus on bonds with the potential to offer attractive current income, typically looking for bonds that can provide consistently attractive current yields or that are trading at competitive market prices. A portion of the fund's assets may be allocated to "discount" bonds, which are bonds that sell at a price below their face value, or to "premium" bonds, which are bonds that sell at a price above their face value.The fund's allocation either to discount bonds or to premium bonds will change along with our changing views of the current interest-rate and market environment.We may also look to select bonds that are most likely to obtain attractive prices when sold.

What other factors influenced the fund's performance?

Although rising short-term interest rates in a growing economy historically have tended to erode bond prices, high-quality municipal bonds retained much of their value during the reporting period.We attribute the market's resilience to persistently low inflation, which appeared to reassure fixed-income investors, robust investor demand for tax-exempt income and a declining supply of newly issued securities.

The fund also benefited during the reporting period from better fiscal conditions for most states and municipalities.The strong U.S. economy helped most states achieve budget surpluses for their current fiscal years, enabling them to reduce their borrowing activity in the municipal bond market.At the same time, investor demand for newly issued securities has remained ample, putting upward pressure on bond prices.

Because we expected short-term interest rates to rise more steeply than long-term rates in this environment, we generally emphasized securities with maturities in the 20- to 30-year range, and we maintained relatively light exposure to intermediate- and shorter-term bonds. Indeed, longer-term securities performed better than other maturities for most of the reporting period, enabling the fund to participate fully in the market's strength. In March and April 2006, however, prices of longer-term securities began to decline as investors grew more concerned about potential inflationary pressures, including renewed volatility in energy prices. Still, the market's recent weakness was not enough to erase the fund's positive absolute returns for the reporting period overall.

4


Finally, a number of the fund's holdings were "pre-refunded" by their issuers during the reporting period, a process in which new debt is issued at lower rates and a portion of the proceeds is set aside to redeem existing, higher yielding issues at the first available opportunity. Because repayment of principal is assured when bonds are pre-refunded, their prices generally rise.

What is the fund's current strategy?

Although we believe the Federal Reserve Board may be close to the end of the current credit tightening cycle, we expect one or more additional rate hikes in the months ahead before it pauses to assess the impact of a more restrictive monetary policy on inflation and economic growth.Therefore, we have maintained the fund's emphasis on longer-term securities. However, we may adjust this strategy when we see signs that interest rates have peaked, including possibly shifting our focus toward securities in the intermediate-term range.

1    Total return includes reinvestment of dividends and any capital gains paid. Past performance is no 
    guarantee of future results. Share price, yield and investment return fluctuate such that upon 
    redemption, fund shares may be worth more or less than their original cost. Income may be subject 
    to state and local taxes, and some income may be subject to the federal alternative minimum tax 
    (AMT) for certain investors. Capital gains, if any, are fully taxable. Return figure provided reflects 
    the absorption of certain fund expenses by The Dreyfus Corporation pursuant to an undertaking 
    currently in effect. Had these expenses not been absorbed, the fund's return would have been lower.

Past performance is not predictive of future performance.The fund's performance shown in the graph and table does not
reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.
The above graph compares a $10,000 investment made in Dreyfus Insured Municipal Bond Fund, Inc. on 4/30/96 to
a $10,000 investment made in the Lehman Brothers Municipal Bond Index (the "Index") on that date. All dividends
and capital gain distributions are reinvested.
The fund invests primarily in municipal securities which are insured as to the timely payment of principal and interest by
recognized issuers of municipal securities.The fund's performance shown in the line graph takes into account all applicable
fees and expenses.The Index, unlike the fund, is an unmanaged total return performance benchmark for the long-term,
investment-grade tax-exempt bond market, calculated by using municipal bonds selected to be representative of the
municipal market overall; however, the bonds in the Index are generally not insured. The Index also does not take into
account charges, fees and other expenses. All of these factors can contribute to the Index potentially outperforming or
underperforming the fund. Further information relating to fund performance, including expense reimbursements, if
applicable, is contained in the Financial Highlights section of the prospectus and elsewhere in this report. Neither fund
shares nor the market value of its portfolio securities are insured.

COMPARING YOUR FUND'S EXPENSES WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC's method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund's expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds.All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

Expenses and Value of a $1,000 Investment assuming a hypothetical 5% annualized return for the six months ended April 30, 2006

Expenses paid per $1,000     $ 4.06 
Ending value (after expenses)    $1,020.78 

Expenses are equal to the fund's annualized expense ratio of .81%, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Insured Municipal Bond Fund, Inc. (the "fund") is registered under the Investment Company Act of 1940, as amended (the "Act"), as a 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 income tax as is consistent with the preservation of capital. The Dreyfus Corporation (the "Manager" or "Dreyfus") serves as the fund's investment adviser. The Manager is a wholly-owned subsidiary of Mellon Financial Corporation ("Mellon Financial"). Dreyfus Service Corporation (the "Distributor"), a wholly-owned subsidiary of the Manager, is the distributor of the fund's shares, which are sold to the public without a sales charge.

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

The fund enters into contracts that contain a variety of indemnifications. The fund's maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued each business day by an independent pricing service (the "Service") approved by the Board of Directors. 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.

20


(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 accretion of discount and amortization of premium 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.

The fund has an arrangement with the custodian bank whereby the fund receives earnings credits from the custodian when positive cash balances are maintained, which are used to offset custody fees. For financial reporting purposes, the fund includes net earnings credits, if any, as an expense offset in the Statement of Operations.

(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, if any, 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 can be offset by capital loss carryovers it is the policy of the fund not to distribute such gain. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles.

(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 Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

The Fund 21


NOTES TO FINANCIAL STATEMENTS (continued)

At April 30, 2006, the components of accumulated earnings on a tax basis were as follows: undistributed tax-exempt income $34,581, accumulated capital losses $407,575 and unrealized appreciation $4,336,099. In addition, the fund had $141,338 of capital losses realized after October 31, 2005, which were deferred for tax purposes to the first day of the following fiscal year.

The accumulated capital loss carryover is available to be applied against future net securities profits, if any, realized subsequent to April 30, 2006. If not applied,$289,539 of the carryover expires in fiscal 2013 and $118,036 expires in fiscal 2014.

The tax character of distributions paid to shareholders during the fiscal periods ended April 30, 2006 and April 30, 2005 were as follows: tax exempt income $4,804,483 and $5,132,469, ordinary income $0 and $384,076 and long-term capital gains $0 and $1,222,934, respectively.

During the period ended April 30, 2006, as a result of permanent book to tax differences primarily due to the tax treatment for amortization adjustments, the fund decreased accumulated undistributed investment income-net by $27,407, increased accumulated net realized gain (loss) on investments by $158,286 and decreased paid-in capital by $130,879. Net assets were not affected by this reclassification.

NOTE 2—Bank Line of Credit:

The fund participates with other Dreyfus-managed funds in a $350 million redemption credit facility (the "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.

During the period ended April 30, 2006, 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 reimburses the Distributor for distributing the fund's shares, servicing shareholder accounts ("servicing") and for advertising and marketing relating to the fund.The Plan provides for payments to be made at an aggregate annual rate of up to .20% of the value of the fund's average daily net assets.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 the value of the fund's average daily net assets for any full fiscal year. During the period ended April 30, 2006, the fund was charged $99,877 pursuant to the Plan.

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 April 30, 2006, the fund was charged $49,472 pursuant to the transfer agency agreement.

(c) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

(d) A .10% redemption fee is charged and retained by the fund on certain shares redeemed within thirty days following the date of issuance, subject to exceptions, including redemptions made through the use of fund's exchange privilege.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities, during the period ended April 30, 2006, amounted to $43,219,537 and $53,276,976, respectively.

At a meeting of the Board of Directors held on November 14, 2005, the Board considered the re-approval for an annual period of the fund's Management Agreement, pursuant to which the Manager provides the fund with investment advisory and administrative services. The Board members, none of whom are "interested persons" (as defined in the Investment Company Act of 1940, as amended) of the fund, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent, and Quality of Services Provided to the Fund. The Board members received a presentation from representatives of the Manager regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent, and quality of the services provided to the fund pursuant to its Management Agreement.The Manager's representatives reviewed the fund's distribution of accounts and the relationships the Manager has with various intermediaries and the different needs of each. The Manager's representatives noted the diversity of distribution of the fund as well as among the funds in the Dreyfus fund complex, and the Manager's corresponding need for broad, deep, and diverse resources to be able to provide ongoing shareholder services to each of the fund's distribution channels. The Board members also reviewed the number of shareholder accounts in the fund and the fund's asset size.

The Board members also considered the Manager's research and portfolio management capabilities and that the Manager also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements. The Board members also considered the Manager's extensive administrative, accounting, and compliance infrastructure.

Comparative Analysis of the Fund's Performance, Management Fee, and Expense Ratio. The Board members reviewed the fund's performance, management fee, and expense ratio and placed significant emphasis on comparisons to a group of comparable funds and Lipper category averages. The group of comparable funds previously was approved by the Board for this purpose, and was prepared using a Board-approved selec-

tion methodology that was based, in part, on selecting non-affiliated funds reported in the same Lipper category (the "Insured Municipal Debt Funds" category) as the fund.The Board members discussed the results of the comparisons for various periods ended September 30, 2005. The Board noted that the fund's yield performance was higher than the Lipper category averages but lower than the comparison group averages for the 1-year, 3-year, 5-year, and 10-year periods.The Board members noted that the fund's total return performance was higher than the Lipper category averages for the 1-year, 3-year, and 5-year periods, but lower than the Lipper category average for the 10-year period and lower than the comparison group averages for these periods.The Board also noted the Fund's improved relative yield and total return performance for the 1-year period compared with the prior year's results.

The Board members also discussed the fund's management fee and expense ratio and reviewed the range of management fees and expense ratios for the funds in the comparison group. The Board members noted that the fund's management fee was higher than the majority of the management fees for the comparison group funds and that the fund's expense ratio was the same as the comparison group average and lower than the Lipper category average.

The Manager's representatives noted that there were no similarly managed mutual funds, institutional separate accounts, or wrap fee accounts managed by the Manager or its affiliates with similar investment objectives, policies, and strategies (and, as to mutual funds, in the same Lipper category) as the fund.

Analysis of Profitability and Economies of Scale. The Manager's representatives reviewed the dollar amount of expenses allocated and profit received by the Manager and the method used to determine such expenses and profit. The Board received and considered information prepared by an independent consulting firm regarding the Manager's approach to allocating costs to, and determining the profitability of,

28


individual funds and the entire Dreyfus fund complex.The Manager's representatives stated that the methodology had also been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable.The consulting firm also analyzed where any economies of scale might emerge in connection with the management of the fund.The Board members evaluated the analysis in light of the relevant circumstances for the fund, and the extent to which economies of scale would be realized as the fund grows and whether fee levels reflect these economies of scale for the benefit of fund investors. It was noted that economies of scale also could be appropriately realized through an adviser's reinvestment of money back into its business for the benefit of fund shareholders.The Board members also considered potential benefits to the Manager from acting as investment adviser and noted that there were no soft dollar arrangements in effect with respect to trading the fund's portfolio.

It was noted that the Board members should consider the Manager's profitability with respect to the fund as part of their evaluation of whether the fee under the Management Agreement bears a reasonable relationship to the mix of services provided by the Manager, including the nature, extent, and quality of such services and that a discussion of economies of scale is predicated on increasing assets and that, if a fund's assets had been decreasing, the possibility that the Manager may have realized any economies of scale would be less.The Board members also discussed the profitability percentage ranges determined by appropriate court cases to be reasonable given the services rendered to investment companies. It was noted that the profitability percentage for managing the fund was not unreasonable given the fund's overall performance and generally superior service levels provided.

At the conclusion of these discussions, each Board member expressed the opinion that he or she had been furnished with sufficient information to make an informed business decision with respect to contin-

uation of the fund's Management Agreement. Based on their discussions and considerations as described above, the Board members made the following conclusions and determinations.

  • The Board concluded that the nature, extent, and quality of the ser- vices provided by the Manager are adequate and appropriate.
  • The Board was satisfied with the fund's overall performance.
  • The Board concluded that the fee paid to the Manager by the fund was reasonable in light of comparative performance and expense and advisory fee information, costs of the services provided, and profits to be realized and benefits derived or to be derived by the Manager from its relationship with the fund.
  • The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the management of the fund had been adequately considered by the Manager in con- nection with the management fee rate charged to the fund, and that, to the extent in the future it were to be determined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with the information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of the fund's Management Agreement was in the best interests of the fund and its shareholders.
