Action mechanism:
It is an Aerobic Bacillus cereus that produces crystalline proteins. Bt insecticide is a microbial preparation produced by culturing Bt insecticidal bacteria, the mechanism of which is the release of toxic parasporal crystals.
After entering the digestive tract of insects, parasporal crystals (mainly composed of proteins) are destroyed into smaller units by the alkaline intestinal fluid of insects δ- Endotoxin causes the midgut to stop peristalsis and paralysis, the epithelial cells of the midgut to dissociate and stop feeding, and spores germinate in the gut. They enter the blood cavity through the damaged intestinal wall, where they multiply in large numbers, causing pests to die from septicemia. The body of the dead larvae becomes soft and black.
Applications:
Bacillus thuringiensis has a wide insecticidal spectrum and can control hundreds of pests, especially effective against Lepidoptera larvae.
It is the most widely used in vegetables, rice, grain, corn, cotton, fruit trees, tea trees, and forest areas.
