Beans are one of the sources of low-fat protein for human. Cowpea weevil, Callosobruchus maculatus F. (Col.; Chrysomelidae) are one of the major pests of beans crop. The use of chemical compounds such as methyl bromide and phosphine due to the residual and environmental impacts are not recommended to control the pest. Therefore, the use of low-risk measures such as plant compounds and organic acids have been considered as alternatives. In this study, the effect fumigant toxicity of acetic acid, formic acid and citric acid were evaluated in control of C. maculatus in laboratory condition. The experiment was conducted at 25 ± 2 °C 50 ± 5% RH and 6:18 L:D. The LC50 values were calculated as 3.409, 4.878 and 3.80 and 3.013, 3.653 and 3.256 μl / cm3 after 24 and 48 hours, respectively. The result showed that acetic acid was more effective compared to other organic acids in control of C. maculatus. Also the combined effects of acetic acid + citric acid with an average of 80% mortality have high potential for control of the pest and can be used as a low risk insecticide in integrated pest management. However, more experiments are required to investigate the side effects of organic acids before any final conclusion on their application
