%X Three mutants (Bb07240,Pf01120 and Pf01160) were produced and screen by water stress in low water activity media after irradiating blastospores of entomopathogenic fungi Bb07 (Beauveria bassiana) and Pf01 (Pacelomyces fumosoroseus) with ultraviolet light. Rate of blastospore germination and growth of the new strains at reduced water activity and reduced relative humidity were significantly higher than that of their original strains. The result of bioassay indicated that the three mutants were more virulent against peach aphids (Myzus persicae) than the original strains.
