Bacillus Thuringiensis
Bacillus Thuringiensis Israelensis, abbreviated as Bt, also known as Bacillus thuringiensis, is a type of crystal-forming Bacillus that includes many varieties. The bacteria can produce two major toxoids, namely endotoxin (with crystals) and exotoxin. After the pests are fed, the bacteria release toxins, poison the bacteria and stop feeding, and finally the pests under the action of the alkaline digestive juice of the intestines. Death due to hunger and blood and nerve poisoning. Therefore, the bacterium can be used as a microbial low-toxic insecticide for controlling a variety of pests of Orthoptera, Coleoptera, Diptera, Hymenoptera, especially Lepidoptera.

Bacillus thuringiensis has different pathogenic and toxic effects on more than 100 insect pests, such as cotton bollworm, Chinese cabbage insect, poisonous moth, pine caterpillar, corn borer, sorghum borer, etc.
Mechanism of action when the insect nibbleth the spore crystals and spores, the spore crystals dissolve in the intestinal alkaline environment of the insect, releasing the toxin which has a strong killing effect on Lepidoptera larvae.
This toxin causes the midgut paralysis of the larvae, showing poisoning symptoms, and generally does no harm to the crops. After a period of onset, the intestinal wall of the insect is damaged, the toxin enters the blood,causing septicemia, and at the same time the spores multiply rapidly in the digestive tract, accelerating the death of the insect.
Bacillus Thuringiensis Advantage:
1. Strong selectivity and no harm to natural enemies
2.Not affect the activities of soil microorganisms
3.No residual poison, the production of products can be safe to eat
