Semi-Annual Report

This report, including the financial information herein, is
transmitted to the shareholders of MuniYield Florida Insured Fund
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 Shares by issuing Preferred Shares to provide the Common
Shareholders with a potentially higher rate of return. Leverage
creates risks for Common Shareholders, including the likelihood of
greater volatility of net asset value and market price of the Common
Shares, and the risk that fluctuations in the short-term dividend
rates of the Preferred Shares may affect the yield to Common
Shareholders. Statements and other information herein are as dated
and are subject to change.

MuniYield Florida Insured Fund
TO OUR SHAREHOLDERS
For the six months ended April 30, 1998, the Common Shares of
MuniYield Florida Insured Fund earned $0.494 per share income
dividends, which included earned and unpaid dividends of $0.067.
This represents a net annualized yield of 6.51%, based on a month-
end net asset value of $15.29 per share. Over the same period, the
total investment return on the Fund's Common Shares was +2.51%,
based on a change in per share net asset value from $15.50 to
$15.29, and assuming reinvestment of $0.498 per share income
dividends and $0.097 per share capital gains distributions.
For the six months ended April 30, 1998, the Fund's Auction Market
Preferred Shares had an average yield of 3.93%.
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 refinancings.
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 Florida Insured Fund
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 months ended April 30, 1998, we shifted from our
defensive position to a more constructive investment outlook. We
expected economic growth to slow along with a continued reduction in
inflation as a result of the declines in Asian equity markets. As of
April 30, 1998, only one of these expectations had been met.
Inflation has continued to fall but economic growth has not slowed.
Looking forward to the balance of 1998, we expect to maintain a
constructive outlook. We believe the continued instability of the
Asian equity markets will have a negative impact on the US economy,
allowing inflation and interest rates to decline further.
The yield on the Fund's Auction Market Preferred Shares has been
trading between 3.15%--4.10% during the past 12 months. Recently,
the yield has been at the higher end of this range because of
temporary tax season pressure, but is expected to return to the
3.40% level in the next few weeks. Leverage continues to benefit the
Fund's Common Shareholders by significantly augmenting their yield.
However, should the spread between short-term and long-term tax-
exempt interest rates narrow, the benefits of leverage will decline
and, as a result, reduce the yield to the Fund's Common Shares. (For
a complete explanation of the benefits and risks of leveraging, see
page 4 of this report to shareholders.)

We appreciate your ongoing interest in MuniYield Florida Insured
Fund, and we look forward to serving your investment needs in the

PORTFOLIO INSURANCE
MuniYield Florida Insured Fund 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 Florida Insured Fund utilizes leveraging to seek to
enhance the yield and net asset value of its Common Shares. However,
these objectives cannot be achieved in all interest rate
environments. To leverage, the Fund issues Preferred Shares, which
pay 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 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 Shares. However,
in order to benefit Common 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 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 Share
capitalization of $100 million and the issuance of Preferred Shares
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 Shares 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 Shares.
In this case, the dividends paid to Preferred Shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common 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 Shares will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Shares (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
Shares' net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Shares does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Shares 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 Common Shares 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 Florida Insured Fund (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 Shares on a weekly basis. The Fund's
Common Shares are listed on the New York Stock Exchange under the
symbol MFT. 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 their fair value
as determined in good faith by or under the direction of the Board
of Trustees 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 general supervision
of the Board of Trustees.
(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.
MuniYield Florida Insured Fund
April 30, 1998
(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.
(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates. Distributions in excess of
realized capital gains are due primarily to differing tax treatments
for futures transactions.
2. Investment Advisory Agreement and
Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.
FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee at an annual rate of 0.50% of
the Fund's average weekly net assets, including proceeds from the
issuance of Preferred Shares.
Accounting services are provided to the Fund by FAM at cost.
Certain officers and/or trustees of the Fund are officers and/or
directors of FAM, PSI, and/or ML & Co.
3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the six months ended April 30, 1998 were $39,796,709 and
$40,527,667, respectively.
Net realized gains for the six months ended April 30, 1998 and net
unrealized gains as of April 30, 1998 were as follows:
Realized Unrealized
Gains Gains
Long-term investments $ 1,306,731 $ 9,856,462
----------- -----------
Total $ 1,306,731 $ 9,856,462
=========== ===========
As of April 30, 1998, net unrealized appreciation for Federal income
tax purposes aggregated $9,856,462, of which $10,217,747 related to
appreciated securities and $361,285 related to depreciated
securities. The aggregate cost of investments at April 30, 1998 for
Federal income tax purposes was $176,175,894.
4. Capital Share Transactions:
The Fund is authorized to issue an unlimited number of capital
shares, including Preferred Shares, par value $.10 per share, all of
which were initially classified as Common Shares. The Board of
Trustees is authorized, however, to reclassify any unissued shares
of capital without approval of the holders of Common Shares.
Common Shares
Shares issued and outstanding during the six months ended April 30,
1998 increased by 27,352 as a result of dividend reinvestment and
during the year ended October 31, 1997 remained constant.
Preferred Shares
Auction Market Preferred Shares ("AMPS") are Preferred Shares of the
Fund that entitle their holders to receive cash dividends at an
annual rate that may vary for the successive dividend periods. The
yield in effect at April 30, 1998 was 4.10%.
As of April 30, 1998, there were 2,400 AMPS 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
each auction at an annual rate ranging from 0.25% to 0.375%,
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 $45,771 as commissions.
5. Subsequent Event:
On May 7, 1998, the Fund's Board of Trustees declared an ordinary
income dividend to Common Shareholders in the amount of $.067139 per
share, payable on May 28, 1998 to shareholders of record as of May
21, 1998.
