Effect of allyl disulfide from essential oil of garlic on adults of four species of stored grain insects, callosobruchus chinensis (l.), callosobruchus macujatus (f.), tribojium castaneum (hbst.) and sitophijus oryzae (l.) [electronic resource].

Includes references.

Allyl disulfide, a major constttuent of the essential oil garlic, Mum sa/ivum, was tested against CaOosobruchus chinensis (L), C. macula/us (F.), Tribolium castaneum (Hbst.) and Sitophilus oryzae (L.) for fumigant and contact toxicity. The study revealed that ailyl disulfide was more toxic to C. chinesis than the other insects in both fumigant and contact toxicity. The Le50 values of fumigant toxicity were 0.64, 0.63, 0.46 and 3. 75~ULair for C. chinensis, T.castaneum and S. oryzae, respectively. As for the contact toxicity, which was performed using topical application, the L050 values were 22.1, 22.8, 24.2 and 94.0 ppm nnsect for C. chinensis, C. maculatus, T.castaneum and S. oryzae, respectively.
