Semi-Annual Report

This report, including the financial information herein, is
transmitted to the shareholders of MuniYield Michigan 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 months ended April 30, 1999, the Common Stock of
MuniYield Michigan Insured Fund, Inc. earned $0.432 per share income
dividends, which included earned and unpaid dividends of $0.066.
This represents a net annualized yield of 5.62%, based on a month-
end per share net asset value of $15.48. Over the same period, the
total investment return on the Fund's Common Stock was +1.32%, based
on a change in per share net asset value from $15.93 to $15.48, and
assuming reinvestment of $0.493 per share ordinary income dividends
and $0.160 per share capital gains distributions.
For the six-month period ended April 30, 1999, the Fund's Auction
Market Preferred Stock had an average yield of 3.23%.
The Municipal Market Environment
During the six months ended April 30, 1999, long-term bond yields
generally moved higher. From November 1998 through mid-January 1999,
long-term bond yields traded in a relatively narrow range. However,
during February, a number of economic indicators were released that
suggested that economic growth in the United States would likely
remain strong throughout most of 1999. Consequently, long-term US
Treasury bond yields rose more than 60 basis points (0.60%) to 5.70%
by early March. During the remainder of the six-month period, US
Treasury bond yields traded between 5.50% and 5.70% as the lack of
inflationary pressures offset much of the concerns generated by
continued strong economic growth. During most of the period, long-
term, uninsured tax-exempt bond yields exhibited far less volatility
and were largely stable. Also, long-term municipal bond yields rose
just 5 basis points to 5.29% at the end of April 1999, as measured
by the Bond Buyer Revenue Bond Index.
In recent months, the tax-exempt market was better able to withstand
much of the upward pressure on bond yields because of its stronger
technical position. While the continued positive inflationary
environment limited some of the recent increases in taxable bond
yields, a deteriorating supply/demand position helped push taxable
bond yields significantly higher than municipal bond yields. Much of
the US Treasury bond market's underperformance in recent months can
be attributed to the large amounts of taxable corporate issuance.
Large taxable corporate underwritings reduced the demand for US
Government securities in recent months, pushing US Treasury bond
yields higher.
On the other hand, the tax-exempt bond market enjoyed only limited
new-issue supply. During the six months ended April 30, 1999, more
than $123 billion in new long-term tax-exempt securities was
underwritten, a decline of 10% compared to the same period a year
ago. Municipalities issued less than $60 billion in long-term tax-
exempt securities during the three months ended April 30, 1999, a
decline of 25% compared to the April 30, 1998 quarter. More
recently, the rate of new tax-exempt issuance has declined even
further. During April 1999, just over $15 billion in long-term tax-
exempt securities was marketed, a decline of over 33% compared to
April 1998 levels. As municipal bond yields fell and stabilized in
recent quarters, the ability of municipalities to refinance existing
higher-couponed debt declined. This led to a significant decrease in
refunding issuance and an overall drop in new municipal bond supply.
When coupled with ongoing, moderate retail and institutional demand,
the tax-exempt bond market was able to avoid much of the yield
volatility exhibited by US Treasury securities.
Looking ahead, the expected combination of moderate economic growth
in the United States and continued negligible inflation suggests a
relatively stable interest rate environment. However, in recent
years, bond yields reached their annual peaks in early May and
declined for the remainder of the year. A meaningful decline in
fixed-income bond yields would require either evidence of a
significant slowdown in the US economy or the resumption of concerns
regarding renewed shocks to the world's economic system. Currently,
neither condition exists or seems likely in the immediate future. In
our opinion, this suggests a continuation of the narrow trading
ranges seen in recent months.
Portfolio Strategy
During the last several months, we adopted a more neutral investment
strategy, since indicators pointed to a continuation of healthy
domestic economic growth and benign inflation. In addition, we
believed that long-term tax-exempt bond yields would continue to
trade in a relatively narrow range, centered around present levels.
Consequently, we focused on income-producing securities rather than
those issues with the potential for capital gains. Should the tax-
exempt bond market perform as expected, coupon income will be the
more important component of the Fund's performance. MuniYield
Michigan Insured Fund, Inc. remained fully invested for most of the
past several months. We expect to maintain this position going
forward in order to seek to enhance shareholder income.
Short-term tax-exempt yields exhibited considerable volatility in
recent months. Interest rates paid to the Fund's Preferred Stock
shareholders traded below 3% in December 1998, reflecting heightened
investor demand at year-end. Current short-term interest rate levels
reflect tax season-related pressures, which we expect to abate soon.
During the six-month period ended April 30, 1999, leveraging
generated a significant incremental yield to the Fund's Common Stock
shareholders. Because we believe that the Federal Reserve Board's
monetary policy is likely to remain in a narrow range for the
remainder of the year, we expect short-term tax-exempt interest
rates to remain at, or slightly below, current levels. However,
should the spread between short-term and long-term interest rates
narrow, the benefits of the leverage will decline and, as a result,
reduce the yield to the Fund's Common Stock. (For a complete
explanation of the benefits and risks of leveraging, see page 3 of
this report to shareholders.)
In Conclusion
We appreciate your ongoing interest in MuniYield Michigan Insured
Fund, Inc., and we look forward to serving your investment needs in
the months and years ahead.

THE BENEFITS AND RISKS OF LEVERAGING
MuniYield Michigan 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.
As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities.

NOTES TO FINANCIAL STATEMENTS
1. Significant Accounting Policies:
MuniYield Michigan Insured Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a non-diversified,
closed-end management investment company. The Fund's financial
statements are prepared in accordance with generally accepted
accounting principles which may require the use of management
accruals and estimates. 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 MIY. 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 written or purchased are valued at the last
sale price in the case of exchange-traded options. In the case of
options traded in the over-counter-market, valuation is the last
asked price (options written) or the last bid price (options
purchased). Securities with remaining maturities of sixty days or
less are valued at amortized cost, which approximates market value.
Securities and assets 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.
MuniYield Michigan Insured Fund, Inc.
April 30, 1999
(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 post-October losses.
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 Stock.
Accounting services are provided to the Fund by FAM at cost.
Certain officers and/or directors 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, 1999 were $30,526,235 and
$37,237,384, respectively.
Net realized gains for the six months ended April 30, 1999 and net
unrealized gains as of April 30, 1999 were as follows:
Realized Unrealized
Gains Gains
Long-term investments $1,353,720 $10,914,469
---------- -----------
Total $1,353,720 $10,914,469
========== ===========
As of April 30, 1999, net unrealized appreciation for Federal income
tax purposes aggregated $10,914,469, of which $11,123,383 related to
appreciated securities and $208,914 related to depreciated
securities. The aggregate cost of investments at April 30, 1999 for
Federal income tax purposes was $153,702,799.
4. Capital Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of capital stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of capital
stock without approval of holders of Common Stock.
Common Stock
Shares issued and outstanding during the six months ended April 30,
1999 increased by 57,164 as a result of dividend reinvestment and
during the year ended October 31, 1998 remained constant.
Preferred Stock
Auction Market Preferred Stock ("AMPS") are shares of Preferred
Stock of the Fund, with a par value of $.05 per share and a
liquidation preference of $25,000 per share, 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, 1999 was 3.55%.
Shares issued and outstanding during the six months ended April 30,
1999 and the year ended October 31, 1998 remained constant.
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, 1999, Merrill Lynch, Pierce, Fenner & Smith Incorporated,
an affiliate of FAM, earned $41,754 as commissions.
5. Subsequent Event:
On May 6, 1999, the Fund's Board of Directors declared an ordinary
income dividend to Common Stock shareholders in the amount of
$.065546 per share, payable on May 27, 1999 to shareholders of
record as of May 21, 1999.

YEAR 2000 ISSUES
Many computer systems were designed using only two digits to
designate years. These systems may not be able to distinguish the
Year 2000 from the Year 1900 (commonly known as the "Year 2000
Problem"). The Fund could be adversely affected if the computer
systems used by the Fund's management or other Fund service
providers do not properly address this problem before January 1,
2000. The Fund's management expects to have addressed this problem
before then, and does not anticipate that the services it provides
will be adversely affected. The Fund's other service providers have
told the Fund's management that they also expect to resolve the Year
2000 Problem, and the Fund's management will continue to monitor the
situation as the Year 2000 approaches. However, if the problem has
not been fully addressed, the Fund could be negatively affected. The
Year 2000 Problem could also have a negative impact on the
securities in which the Fund invests, and this could hurt the Fund's
investment returns.
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.
