Why are the spores of Bacillus thuringiensis used as bioinsecticide?

उत्तर
The spores of Bacillus thuringiensis are used as a bioinsecticide because they produce Bt toxin, a protein that is toxic to certain insects. When ingested by pests, the toxin activates in their alkaline gut, destroys gut cells, and kills the insect. This makes it a natural, specific, and eco-friendly insect control method.
