Semi-Annual Report

This report, including the financial information herein, is
transmitted to the shareholders of MuniYield Insured Fund, Inc. for
their information. It is not a prospectus, circular or
representation intended for use in the purchase of shares of the
Fund or any securities mentioned in the report. Past performance
results shown in this report should not be considered a
representation of future performance. The Fund has leveraged its
Common Stock by issuing Preferred Stock to provide the Common Stock
shareholders with a potentially higher rate of return. Leverage
creates risks for Common Stock shareholders, including the
likelihood of greater volatility of net asset value and market price
of shares of the Common Stock, and the risk that fluctuations in the
short-term dividend rates of the Preferred Stock may affect the
yield to Common Stock shareholders. Statements and other information
herein are as dated and are subject to change.

TO OUR SHAREHOLDERS
For the six-month period ended April 30, 1998, the Common Stock of
MuniYield Insured Fund, Inc. earned $0.480 per share income
dividends, which included earned and unpaid dividends of $0.070.
This represents a net annualized yield of 6.19%, based on a month-
end per share net asset value of $15.62. Over the same period, the
total investment return on the Fund's Common Stock was +2.56%, based
on a change in per share net asset value from $15.84 to $15.62, and
assuming reinvestment of $0.484 per share income dividends and
$0.119 per share capital gains distributions.
The average yields of the Fund's Auction Market Preferred Stock for
the six-month period ended April 30, 1998 were: Series A, 3.89%;
Series B, 3.85%; Series C, 3.86%; Series D, 4.00%; Series E, 3.94%;
Series F, 4.37%; and Series G, 3.85%.
The Municipal Market Environment
During the six months ended April 30, 1998, bond yields generally
moved lower, and by mid-January 1998 had declined to recent historic
lows. Long-term US Treasury bond yields declined 20 basis points
(0.20%) during the same period and stood at 5.95% by April 30, 1998.
Similarly, long-term uninsured tax-exempt bond yields, as measured
by the Bond Buyer Revenue Bond Index, fell approximately 35 basis
points to 5.25%, a level not seen since the mid-1970s. While low
inflation has supported lower interest rates, much of the decline in
bond yields in late 1997 and early 1998 was driven more by the
turmoil in Asian financial markets than by domestic economic
fundamentals. Weak economic conditions in Asia were expected to
negatively impact US growth through reduced export demand.
Additionally, inflation in the United States was also expected to
decline in response to lower prices on goods imported from Asian
manufacturers.
However, in recent months, many investors have become increasingly
concerned that most of the downturn in Asia, especially in Japan,
has already occurred and any future deterioration will not be severe
enough to constrain US economic growth and inflationary pressures.
These concerns served to push interest rates higher in the latter
part of the period, causing fixed-income yields to retrace much of
their earlier gains.
Thus far in 1998, the municipal bond market has experienced
unexpectedly strong supply pressures. These supply pressures have
prevented tax-exempt bond yields from declining as much as US
Treasury bond yields. Over the last six months, more than $135
billion in new tax-exempt bonds were underwritten, an increase of
over 40% compared to the same period a year ago. During the last
three months, municipalities issued more than $72 billion in new
securities, an increase of over 60% compared to the same three-month
period in 1997. Additionally, corporate issuers have also viewed
current interest rate levels as an opportunity to issue significant
amounts of taxable securities. Thus far in 1998, more than $100
billion in investment-grade corporate bonds have been underwritten,
an increase of over 60% relative to the comparable period a year
ago. This sizeable corporate bond issuance has tended to support
generally higher fixed-income yields and reduce the demand for tax-
exempt bonds.
However, the recent pace of new municipal bond issuance is unlikely
to be maintained. Continued increases in bond issuance will require
lower and lower tax-exempt bond yields to generate the economic
savings necessary for additional municipal bond refinancing.
Preliminary estimates for 1998 total municipal bond issuance are
presently in the $200 billion--$225 billion range. These estimates
suggest that recent supply pressures are likely to abate later in
the year. Municipal bond investors received approximately $30
billion earlier this year in coupon payments, bond maturities and
proceeds from early redemptions. The demand generated by these
assets has helped offset the increase in supply seen thus far this
year. Furthermore, looking ahead, June and July have also tended to
be periods of strong investor demand as seasonal factors are likely
to generate strong income flows similar to those seen earlier this
year.
MuniYield Insured Fund, Inc.
April 30, 1998
It is also possible that at least some of the recent economic
strength seen in the United States will be reversed in the coming
months. A particularly mild winter has been partially responsible
for a strong housing sector, as well as other construction
industries. This recent strong trend may not be sustained and may
lead to weaker construction growth later this year. Additionally,
strong economic growth in 1997 and the increased use of electronic
tax filing have resulted in larger and earlier Federal and state
income tax refunds to many individuals. These refunds appear to have
supported strong consumer spending in recent months, but may be
borrowing against weaker spending later this year. In addition, the
continued impact of the Asian financial crisis on the US domestic
economy's future growth remains unclear. Barring a dramatic and
unexpected resurgence of domestic inflation, we do not believe that
the Federal Reserve Board will be willing to raise interest rates
until the full impact of the Asian situation can be established.
All these factors suggest that over the near term, tax-exempt as
well as taxable bond yields are unlikely to rise by any appreciable
amount. Recent supply pressures have caused municipal bond yield
ratios to rise relative to US Treasury bond yields. At April 30,
1998, long-term tax-exempt bond yields were at attractive yield
ratios relative to comparable US Treasury securities (over 90%), and
well in excess of their expected range of 85%--88%. Any further
pressure upon the municipal market may well represent a very
attractive investment opportunity.
Portfolio Strategy
During the six-month period ended April 30, 1998, we continued to
follow the portfolio strategy that we had adopted during the prior
six-month period. At that time, our outlook was constructive toward
the municipal market because we believed any risk was biased toward
lower rather than higher interest rates. Therefore, we followed a
more aggressive investment strategy. We have essentially maintained
a fully invested position since that time and have kept cash
reserves at a minimum to seek to enhance the Fund's dividend and
capital appreciation potential.
Looking ahead, we expect to remain fully invested during the next
several months. We will continue to monitor economic data for any
signs of inflationary pressure or economic downturn so that we can
modify our portfolio strategy in an effort to seek to preserve the
Fund's capital or enhance total return.
In Conclusion
We appreciate your ongoing interest in MuniYield Insured Fund, Inc.,
and we look forward to assisting you with your financial needs in
the months and years ahead.

PORTFOLIO INSURANCE
MuniYield Insured Fund, Inc. seeks to provide its shareholders with
the benefits of an insured municipal bond portfolio. Previously, the
Fund generally achieved this objective by limiting at least 80% of
portfolio investments to municipal bonds insured under policies
obtained by the issuer or another party, including the Fund itself,
and issued by insurance carriers with claims paying ability ratings
of AAA or its equivalent from at least two nationally recognized
rating agencies, such as Standard & Poor's Ratings Services, Moody's
Investors Service, Inc., or Fitch IBCA, Inc. In order to increase
the Fund's flexibility to obtain appropriate investments, the Fund
has modified its practice with respect to the ratings criteria it
applies to the carriers that provide insurance for the municipal
bonds in its portfolio. Currently, the Fund may also invest in
municipal bonds insured by, or may itself purchase an insurance
policy for all or a portion of its municipal bond portfolio from, an
insurance carrier with a claims paying ability rating of AAA or its
equivalent from at least one of such nationally recognized rating
agencies. There can be no assurance that insurance of the kind
described above will continue to be available to the Fund, and the
Fund has reserved its right to modify its criteria for portfolio
insurance, or discontinue its policy of maintaining an insured
portfolio if such insurance is no longer available or if the cost of
such insurance outweighs its benefits to the Fund. Although we
periodically review the financial condition of each insurer, there
can be no assurance that the insurers will be able to honor their
obligations under the circumstances of any claim thereunder.

THE BENEFITS AND RISKS OF LEVERAGING
MuniYield Insured Fund, Inc. utilizes leveraging to seek to enhance
the yield and net asset value of its Common Stock. However, these
objectives cannot be achieved in all interest rate environments. To
leverage, the Fund issues Preferred Stock, which pays dividends at
prevailing short-term interest rates, and invests the proceeds in
long-term municipal bonds. The interest earned on these investments
is paid to Common Stock shareholders in the form of dividends, and
the value of these portfolio holdings is reflected in the per share
net asset value of the Fund's Common Stock. However, in order to
benefit Common Stock shareholders, the yield curve must be
positively sloped; that is, short-term interest rates must be lower
than long-term interest rates. At the same time, a period of
generally declining interest rates will benefit Common Stock
shareholders. If either of these conditions change, then the risks
of leveraging will begin to outweigh the benefits.
To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred Stock
for an additional $50 million, creating a total value of $150
million available for investment in long-term municipal bonds. If
prevailing short-term interest rates are approximately 3% and long-
term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.
In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.
MANAGED DIVIDEND POLICY
The Fund's dividend policy is to distribute substantially all of its
net investment income to its shareholders on a monthly basis.
However, in order to provide shareholders with a more consistent
yield to the current trading price of shares of Common Stock of the
Fund, the Fund may at times pay out less than the entire amount of
net investment income earned in any particular month and may at
times in any month pay out such accumulated but undistributed income
in addition to net investment income earned in that month. As a
result, the dividends paid by the Fund for any particular month may
be more or less than the amount of net investment income earned by
the Fund during such month. The Fund's current accumulated but
undistributed net investment income, if any, is disclosed in the
Statement of Assets, Liabilities and Capital, which comprises part
of the Financial Information included in this report.

NOTES TO FINANCIAL STATEMENTS
1. Significant Accounting Policies:
MuniYield Insured Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. These unaudited financial statements
reflect all adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim period
presented. All such adjustments are of a normal recurring nature.
The Fund determines and makes available for publication the net
asset value of its Common Stock on a weekly basis. The Fund's Common
Stock is listed on the New York Stock Exchange under the symbol MYI.
The following is a summary of significant accounting policies
followed by the Fund.
(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such securities. Financial
futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of
such exchanges. Options, which are traded on exchanges, are valued
at their last sale price as of the close of such exchanges or,
lacking any sales, at the last available bid price. Securities with
remaining maturities of sixty days or less are valued at amortized
cost, which approximates market value. Securities for which market
quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of
Directors of the Fund, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.
(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt markets. Losses may
arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.
* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts
for the purpose of hedging the market risk on existing securities or
the intended purchase of securities. Futures contracts are contracts
for delayed delivery of securities at a specific future date and at
a specific price or yield. Upon entering into a contract, the Fund
deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to
the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as variation margin
and are recorded by the Fund as unrealized gains or losses. When the
contract is closed, the Fund records a realized gain or loss equal
to the difference between the value of the contract at the time it
was opened and the value at the time it was closed.
* Options--The Fund is authorized to write covered call options and
purchase put options. When the Fund writes an option, an amount
equal to the premium received by the Fund is reflected as an asset
and an equivalent liability. The amount of the liability is
subsequently marked to market to reflect the current market value of
the option written.
When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired, or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).
Written and purchased options are non-income producing investments.
(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.
(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

NOTES TO FINANCIAL STATEMENTS (concluded)
(e) Offering costs--Direct expenses relating to the issuance of
Common Stock resulting from the reorganization were charged to
capital.
(f) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

constant and during the year ended October 31, 1997 increased by
4,800 pursuant to a plan of reorganization. As of April 30, 1998,
there were 17,600 AMPS shares authorized, issued and outstanding
with a liquidation preference of $25,000 per share.
The Fund pays commissions to certain broker-dealers at the end of

calculated on the proceeds of each auction. For the six months ended
April 30, 1998, Merrill Lynch, Pierce, Fenner & Smith Inc., an
affiliate of FAM, earned $222,050 as commissions.
