Abstract: The research on the survival ability of Metarrhizium anisopliae(MA4、JF842、JF86C、JF883、JF813E)shows that the CFUs (colony forming unit) of Metarrhizium anisopliae survived in soil decreased slowly within the first two months, but after two months, the CFUs dropped sharply every month.The CFUs of Metarrhizium anisopliae could be monitored in level of 103-104CFU /sample after 1 year. JF86C and JF883 have more strong survival ability in soil. Too high quantity of spores was detrimental to the long survival of Metarrhizium anisopliae. The sporulation of Metarrhizium anisopliae kept relatively stable in soil.
