, bacteria: to spores, spore-free bacteria, coli most research.
Spores can produce spores resistant to adverse environments, and in the process of growth and development can form companion spore crystals with protein toxins, for a variety of insects, especially for scaly fin insects have a strong toxic effect, at present, the commonly used bacterial insecticides at home and abroad are Suyun Bacillus, Bacillus B, Japanese golden turtle bacteria (including Japanese golden turtle spores B and slow-dead spores B two species).
