摘　　要：小木蠹蛾 (HolcocerusinsulerisStaudinger)雄蛾触角对标准化合物Z3 14:Ac、Z3E5 14:Ac、E3 14:Ac和Z9 14:Ac有明显的电位反应。但林间诱蛾试验结果表明 :只有Z3 14:Ac对小木蠹蛾具有显著的引诱活性 ,且具有专一性。一个含 5 0 0 μgZ3 14:Ac的诱捕器日平均诱蛾 2 6 6头 ,为一头活雌蛾日诱蛾数的 1 8倍。成虫发生期诱蛾量的变化能准确反映林间小木蠹蛾发生与消长的情况。性诱剂Z3 14:Ac的发展 ,为小木蠹蛾的综合防治提供一条新的途径。The EAG responses of male Holcocerus insuleris Staudinger to standard compounds Z3-14:Ac,Z3E5-14:Ac,E3-14:Ac and Z9-14:Ac were strong,but only Z3-14:Ac showed an obvious attraction and specificity in trapping tests.On an average,2.66 male moths were caught by a trap baited with 500μg of Z3-14:Ac per day,which was 1.8 time as many as the moths caught by a trap baited with one virgin female.The attractant-baited trap can be used to detect both the presence and density of the moths in the field.The sex attractant Z3-14:Ac discovered will provide a new way for integrated prevention and control of Holcocerus insuleris Staudinger.
