Vedclass · Answer

(A) $Bacillus 	ext{ } thuringiensis$ (Bt) produces a specific insecticidal protein known as the cry protein or endotoxin.When the caterpillars of insect pests ingest these bacterial spores or crystals, the alkaline $pH$ of the insect gut solubilizes the crystals and releases the active toxin.This active toxin binds to the surface of the midgut epithelial cells and creates pores, causing cell swelling and lysis.This process eventually leads to the death of the insect larvae, thereby controlling the pest population.

How has the bacterium $Bacillus \text{ } thuringiensis$ helped us in controlling caterpillars of insect pests?
