抄録

An entomogenous fungus, Beauveria tenella, was used to control of the most serious insect pest, Psacothea hilaris, in mulberry plantation of eastern part of Japan. Mass productions of conidia of B. tenella were carried out with several kinds of organic solid materials, and wheat bran as basic culture substrate was most effective for conidial production. Approximately 109conidia/g of dried wheat bran were produced after 15 days at 25°C. A two step culture technique for mass production of B. tenella conidia showed good effect to shortning the cultural period and to reduce the contamination by other microorganisms. First B. tenella was produced as hyphal bodies by shaken culture, and they were surface-cultured for 10 days at 25°C on wheat bran in trays for sporulation. In the field cage tests, 1-3kg/are of wheat bran with B. tenella conidia were applied only one time on the field surface of mulberry plantation after the release of adult pest insects. Cumulative mortalities of adult insects for 30 days averaged 60-90%, respectively. The above results suggest that the regulated application of B. tenella probably has practical value as a microbial insecticide.
