Effects of three preparations of Bt kurstaki and Bt entomocidus to three species of lepidopteran cotton pests were evaluated. Retardation in larval development, reduction in egg production of moths, reduction in pupal weight, and appearance of deformities in pupae and moth populations were observed.
This study did not use transgenic plant material. This study evaluated sublethal effects.
