摘　　要：【目的】为了探明对云斑天牛Batocera horsfieldi(Hope)有效的引诱物质。【方法】研究了云斑天牛对白蜡树、山核桃、黄山栾树和野蔷薇4种寄主植物的室内取食偏好性,采用动态顶空吸附法结合气相色谱-质谱联用技术(GC-MS)分析了植物挥发物成分,然后利用触角电位-气相色谱联用技术(GC-EAD)测定植物挥发物对云斑天牛触角的反应,最后对相关化合物进行了野外诱捕试验。【结果】结果表明:云斑天牛最喜欢取食的寄主植物是白蜡树,其次是黄山栾树和山核桃,野蔷薇没有取食;寄主植物挥发物成分中,萜烯类和烷烃类等物质占主要成分,不同寄主植物的挥发物中多种成分存在显著性差异;壬醛引起了云斑天牛显著的GC-EAD反应;最后,林间诱捕试验结果显示,顺-3-己烯醇和壬醛分别在林间诱捕到了一定量的云斑天牛,并且都是雄虫,同时顺-3-己烯醇还诱捕到了星天牛Anoplophora chinensis(Forster)。【结论】试验结果说明,顺-3-己烯醇和壬醛是两种对云斑天牛具有林间引诱效果的植物源物质,同时,顺-3-己烯醇是云斑天牛和星天牛共享的植物源引诱物质。[Objectives] To identify effective lures for trapping Batocera horsfieldi（Hope）. [Methods] The feeding preferences of B. horsfieldi adults on the host plants Carya cathayensis Sarg., Fraxinus chinensis Roxb.、Koelreuteria integrifoliola Merr. and Rosa multiflora Thunb, were studied. We used the adsorption method combined with GC-MS to analyze host plant volatiles extracted from healthy branches of these plants, and GC-EAD to detect the antennal response of adult beetles to the extracted host plant volatiles. We then tested the effectiveness of related compounds as lures for trapping B. horsfieldi in the field. [Results] F. chinensis was the preferred host plant of B. horsfieldi, followed by K. integrifoliola and C. cathayensis; no insects fed on R. multiflora. The main components of host plant volatiles were terpenes and hydrocarbons, and volatiles differed significantly between host plants. Nonanal caused a significant GC-EAD reaction in B. horsfieldi. Field trapping showed that cis-3-hexenol and nonanal were effective in luring male B. horsfieldi into traps. Cis-3-hexenol also attracted Anoplophora chinensis beetles into traps. [Conclusion] Test results indicate that cis-3-hexenol and nonanal are two effective lures for trapping B. horsfieldi in the field. Cis-3-hexenol effectively lures both B. horsfieldi and A. chinensis into traps.
