Extract

In recent years, Bacillus thuringiensis (Berliner) and other entomogenous spore-formers have received increased interest in view of their great potential for insect control. These insect pathogens are generally known as “microbial insecticides” and are so-called because of a spore-associated protein crystalline inclusion which have been shown to be toxic for some insects (Angus 1956). Krieg (1961) lists some one hundred insects, mainly Lepidoptera, which are susceptible to Bacillus thuringiensis and closely related bacteria.
