tests were performed to study the effect of toxicity and repellency of six natural oils, on rice weevil, Sitophilus oryzae and cowpea beetle, Callosobruchus maculatus. Three concentrations of natural oils were tested for the fumigation and four concentrations for repellent effects. The exposure times of fumigation were 5 days for Sitophilus oryzae and 3 days for Callosobruchus maculatus. Data of repellency test were taken at 6, 12, 24 and 48 hours in all experiments. After treatment, the samples were held under constant conditions in rearing room at 30±2°c and 65±5% R.H. Results showed that Callosobruchus maculatus adults were more susceptible to all tested oils than Sitophilus oryzae. Increasing the oils concentration and exposure time increased the fumigant toxicity of oils on insects. These results suggest that oil could be used as potential fumigant and repellenct as a safe pesticide for some of stored-product insects.
