Entomogenous fungi which attack living insects are powerful means for microbiological insecticide. The purpose of this study is to establish the culture conditions and media for mass production of Beauveria sp. C208 which has a broad host range as a potential microbiological pesticide. The temperature and pH range for optimal cultivation of this strain were 28$circ$C and pH 5.0-7.0. For Beauveria sp. C 208, 2% rice straw and 0.6% tryptone were found as the proper carbon and nitrogen sources, considering cell mass, enzyme activities such as chitinase, protease and lipase, and spore concentration.
