The effectiveness of biogas as a grain protectant against Callosobruchus chinensis was evaluated. Biogas was found to have a quicker knock‐down effect and resulted in complete mortality of adults in 16 h. Exposure of different life‐stages of C. chinensis for five days using air‐tight containers indicated that biogas was effective on all life‐stages except the pupal stage. Continuous exposure of infested grains to a high concentration of biogas significantly reduced the level of infestation and loss in grain mass. the results of the study and the methodology developed are expected to meet the grain storage needs of farmers with small land‐holdings.
