摘　　要：储粮害虫是影响储粮安全的重要因素。本研究采用水蒸馏法提取的孜然精油处理玉米象(Sitophilus zeamais),谷蠹(Rhizopertha dominica)和长角扁谷盗(Cryptolestes pusillus)三种储粮害虫,测定了孜然精油的趋避,熏蒸及触杀活性,确定了熏蒸活性的半致死浓度LC_(50)和半致死时间LT_(50)。结果表明,孜然精油对三种储粮害虫均具有良好的控制效果,但三种控制作用随昆虫种类的不同存在差异,C.pusillus对趋避和熏蒸作用最敏感,明显高于其他两种试虫,但在触杀实验中R.dominica对孜然精油表现最敏感。The stored-product insects were vital factor for safety of grain storage. Sitophilus zeamais, Rhizopertha dominica, Cryptolestes pusillus were treated with cumin essential oils （CEO）, which were extracted by water distillation method. The toxicity of repellency,fumigant and contact of CEO against three stored-product adult insects were tested as well as LC50 and LT50 of fumigant toxicity were determined.The result indicated that the control effects of CEO against three kinds of insects were different. C.pusillus was more susceptible on repellency and fumigant than other two insects, however, R. dominica showed the most susceptible on contact toxicity.
