The bioassay on pink bollworm Pectinophora gassypiella (Saunders) was carried out using - endotoxin or purified crystals of an indigenous isolate of bacillus thuringiensis sotto. The crystals were obtained by two phase liq/liq separation technique. LD 50 of the target insect was determined to be 30 g/ml of purified - endotoxin per milliliter of the diet.

Keywords: Insecticidal activity of indinous isolate, Pectinophora gassypiella (Saunders), - endotoxin
