| Abstract: | Two strains of Beauveria bassiana were isolated from infected Carposina niponensis Lep.: Carposinidae] (Strain 46-1) and Holotrichia parallela Col.:Scarabaeidae] (Strain No.4], respectively, which had high spore production. They were then exposed to ultraviolet radiation. Three mutants, two from 46-1 and one from No.4, were obtained. The spore production and the infectivity of the new strains to C. niponensis were steadily higher than that of their parents. Their characters appeared in the mass production and efficacy in the field tests were satisfactory. |
