Abstract

Laboratory studies were conducted to determine the insecticidal activities of five preparations of Bacillus thuringiensis (Bt) on adults and nymphs of Aphis gossypii. Both nymphs and adults were highly susceptible to Bactospeine and Dipel, whereas Thuricide 64 was the least toxic. Results suggest a useful role of Bt formulations; Bactospeine and Dipel, against sucking insects such as aphids on vegetable crops in Kuwait.
