Estimation of Insecticidal Capability of Bacillus Thuringiensis (Sotto) against Pink Bollworm Pectinosphora Gossypiella (Saunders) M. Rafi Sheikh, Dilnawaz Sheikh, S. Baqir Naqvi From Department of Microbiology, University of Karachi, Karachi 75270, Pakistan. 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.
