Fumigant and contact activity of individual and combination of EOs (cumin seed and black pepper oil) were conducted against rice weevil (). Cumin seed and black pepper oil individually exhibited 100% insecticidal activity (Contact and Fumigant) against at 24 and 168 h of exposure in the absence and presence of food, respectively. Overall, differential insect mortality rates were observed with individual EOs; however, cumin seed EO showed higher insecticidal activity in both fumigant and contact bioassays than black pepper EO. Binary mixtures of cumin seed and black pepper oil at 60:40 and 80:20 ratios showed higher toxicity than individual EOs against and further, additive interaction of binary combinations of EOs resulted in complete insecticidal activity of . Thus, we conclude binary mixtures of cumin seed and black pepper EOs might be a promising prophylactic treatment solution for control of to prevent stored grain infestation.
对孜然籽精油和黑胡椒精油单独及组合的熏蒸活性和触杀活性进行了针对米象的测试。孜然籽精油和黑胡椒精油在分别不存在和存在食物的情况下，暴露24小时和168小时时，对米象单独均表现出100%的杀虫活性（触杀和熏蒸）。总体而言，观察到不同精油的昆虫死亡率存在差异；然而，在熏蒸和触杀生物测定中，孜然籽精油的杀虫活性均高于黑胡椒精油。孜然籽精油与黑胡椒精油按60:40和80:20比例的二元混合物对米象的毒性高于单独的精油，此外，精油二元组合的相加作用导致对米象具有完全杀虫活性。因此，我们得出结论，孜然籽精油和黑胡椒精油的二元混合物可能是一种有前景的预防性处理解决方案，用于控制米象以防止储存谷物受到侵害。
