摘　　要：[目的]鉴于荔枝蝽臭液的特性以及粮食储藏中害虫危害的严峻形势,采用三角瓶密闭熏蒸法探讨了荔枝蝽臭液对常见仓储害虫的熏蒸潜力。[结果]结果表明:荔枝蝽雄虫臭液24 h熏蒸毒力的LC50值分别为米象0.5247μL/L、谷蠧6.3125μL/L、四纹豆象2.4068μL/L、黄斑露尾甲3.7753μL/L;荔枝蝽雌虫臭液24 h熏蒸毒力的LC50值分别为米象0.4803μL/L、谷蠧6.3803μL/L、四纹豆象2.5936μL/L、黄斑露尾甲3.7925μL/L。[结论]荔枝蝽臭液对米象、谷蠧、四纹豆象和黄斑露尾甲等仓储害虫具有很好的熏蒸毒力,可望能从荔枝蝽臭液中筛选出有效的天然熏蒸化合物。[Aims]Respecting the characteristics of Tessartoma papillosa（Drury） stink gland secretion and the grim situation of pest damage in grain storage,authors studied the fumigation effect of the stink gland secretion from T.papillosa on four kind of storage pest insects,cowpea weevil,Callosobruchus maculatus Fabricius,rice weevil,Sitophilus oryzae（Linnaeus）,lesser grain borer,Rhyzopertha dominica Fabricius,and driedfruit beetle,Carpophilus hemipterus Linnaeus by fumigation with sealed triangular flasks.[Results] The result showed that the LC50 for 24 h of the T.papillosa male adult stink gland secretion to C.maculates,S.oryzae,R.dominica and C.hemipterus were 0.5247,6.3125,2.4068 and 3.7753 μL/L respectively,while the LC50 for 24 h of T.papillosa female adult stink gland secretion were 0.4803,6.3803,2.5936 and 3.7925 μL/L respectively.[Conclusions] The T.papillosa adult stink gland secretion has very good fumigation to the four stored-grain pest insects.We expected to screen out effective natural compounds with fumigation from the stink gland secretion.
