Medium, component thereof and process employing same for the production of microbial insecticides, such as Bacillus popilliae spores and the like, for the control of Japanese beetles and other insects

摘要

Char waste water, a waste product in sugar refining, derived by water washing spent animal charcoal (char), is useful as a sporulation medium for the production of Bacillus popilliae spores. Bacillus popilliae spores are useful as a microbial insecticide in the control of Japanese beetles since B. popilliae spores cause milky disease in the Japanese beetle and other insects, such as the European chafer.
