Biopesticides
Commercial production of biopesticides is restricted to few bacteria, fungi and viruses. Artificially formulated media with carbon and nitrogen sources serve as substrates for some bacteria and fungi whereas few bacteria and viruses need live insect larvae grown aseptically in large fermentors as substrate because of the obligatory nature of these insect predators. For instance, Bacillus popilliae is produced on a commercial scale in the form of a dust on larvae of Japanese beetles.
