Abstract

Allyl disulfide, a major constituent of the essential oil garlic, Allium sativum, was
tested against Callosobruchus chinensis (L.), c. maculatus (F.), Tribolium castaneum
(Hbst.) and Sitophilus oryzae (L.) for fumigant and contact toxicity. The study
revealed that allyl disulfide was more toxic to C. chinesis than the other insects in both
fumigant and contact toxicity. The LeSO values of fumigant toxicity were 0.64, 0.63,
0.46 and 3. 75IJULair for C. chinensis, T.castaneum and S. oryzae, respectively. As for
the contact toxicity, which was performed using topical application, the LOSO values
were 22.1, 22.8, 24.2 and 94.0 ppm linsect for C. chinen sis, C. maculatus,
T.castaneum and S. oryzae, respectively.
