Newly hatched larvae of pink bollworm (Pectinophora gossypiella) were fed in 1020 g/ml -Endotoxin, B. thuringiensis in an artificial diet. Microtomical studies on dead larvae were carried out. 5 thick sections revealed varied histopathological changes leading to disorientation and rupture of epithelial cells of the gut which ultimately may have lead to paralysis and death of the test insect.

Keywords: -endotoxin, gut epithelium, pectinophora gossypiella, bacillus thuringiensis.
