摘　　要：用触角电位仪测试了棉铃虫成虫对8种小叶杨萎蔫叶片挥发物及挥发物混配后的触角电位反应。实验结果表明,未交配雄蛾对丁香酚、叶绿醇、3-甲基苯甲醛的触角电位反应值较高;处女蛾对环庚酮、2-羟基苯甲醛、3-甲基苯甲醛的触角电位反应值也较大,交配后的雌雄蛾对苯乙醇的触角电位反应值最高。但成虫都对3-甲基苯甲醛有较强烈的反应(EAG值都较大),将对各自有较大触角电位反应值的3种化合物两两进行混配,成虫对混合物的触角电位反应值总体上有增大的趋势,部分有减小的趋势,但减小的电位值较小。The Eleetroantennographic （EAG） responses of Helicoverpa armigera （Htibner） moths to eight kinds of Populus simonii Carr volatiles were tested. The main conclusions as follow： The EAG of unmated male moth response to Eugenol, Ptytol,M--Tolualdehyde were higher than other chemicals; The EAG of virgin moth response to Cycloheptanone, Salicylaldehyde, M--Tolualdehyde were higher than other chemicals; The EAG of mated male and female moth response to Phenethylalcohol was highest than other chemicals. The EAG of all the moth response to M--Tolualdehyde were significant high. The EAG of moth response to mixtures chemicals were higher than signal chemical but EAG of only a few moth response to mixtures chemicals were blower than signal chemical.
