Eleven of 180 local isolates, belonging to Bacillus thuringiensis, were tested for their pathogenicity to pinkbollworm larvae (Pectinophora gossypiella). Three strains, namely RS-25, RS-35, and RS-45, showed a positive insecticidal activity. Their activities based on the crystalline inclusion bodies. The LD50 (hours) for larvae was 8, 12, and 6 hours, respectively.
