| Abstract | ||||
| Toxicity of garlic oil was tested against adults of Callosobruchus chinensis (L.), C. maculatus (F.), Tribolium castaneum(Hbst.) and Sitophilus oryzae(L.) using air tight jars for the fumigant toxicity and topical application for the contact toxicity. The study revealed that adults of C. chinensis were more susceptible to the fumigant toxicity of garlic oil than C. maculatus and T.castaneum, while S. oryzae adults were the least susceptible one. The LC50 values were 0.081, 0.21, 0.22 and 1.771J / L air for the above-mentioned insects, respectively. In the contact bioassay, C. chinensis , C. maculatus and T.castaneum were more susceptible to garlic oil than S oryzae. The LDse values were 10.3, 10.4 , 11.6 and 50.3 ppm/insect for the four tested adult insects, respectively | ||||
