Anoplophora glabripennis (Motschulsky) have a wide range of host plants and endanger both of the health host and the stressed host. In order to find the plant volatiles which affect oviposition behaviors and lay the foundation for the development of green attractant of A. glabripennis. The oviposition preference of three host plants, Salix ohsidare, Melia azedarach and Acer negundo, was tested by laboratory the selective and no-selective oviposition test. The volatile components of three host plants were analyzed by the method of dynamic headspace adsorption to combine Gas Chromatography-Mass Spectrometry (GC/MS). The results of both the se-lective and the no-selective test showed that S. ohsidare was the most suitable for ovipositing by A. glabripen-nis, followed by M. azedarach, and finally A. negundo. The success rate of oviposition of A. glabripennis on S. ohsidare was 69.4%, and the one on A. negundo was 0. The results of host volatiles analysis showed that 16 compounds were found in S. ohsidare, and 11 compounds were detected in M. azedarach and A. negundo. 3-Carene and 2-ethyl-Hexanal only tested in S. ohsidare. The contents of nonanal, styrene, and acetophenone in S. ohsidare were significantly higher than M. azedarach and A. negundo. In the above five compounds, 3-carene and nonanal were reported to show the attraction on A. glabripennis, so we speculate that 3-carene and nonanal may be the effective components for attracting oviposition of A. glabripennis females.%光肩星天牛Anoplophora glabripennis的寄主植物范围广泛,既危害衰弱寄主也危害健康寄主.为了寻找影响光肩星天牛产卵的植物源信息物质,并为研制绿色无公害的光肩星天牛引诱剂奠定基础,通过室内有选择和无选择产卵试验,测定了光肩星天牛对青皮垂柳Salix ohsidare,苦楝Melia azedarach和复叶槭Acer negundo等3种寄主植物的产卵偏好行为,并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3种寄主植物树干挥发物成分.有选择产卵试验和无选择产卵试验结果都表明:光肩星天牛最喜欢在青皮垂柳上产卵,其次是苦楝,最后是复叶槭,其中,有选择产卵试验中,光肩星天牛在青皮垂柳上的产卵成功率达69.4%,在复叶槭上的产卵成功率为0.寄主植物挥发物成分分析结果显示:青皮垂柳和苦楝分别测到16种化合物,复叶槭检测到11种化合物,其中3-蒈烯和2-乙基己醛只在青皮垂柳中检测到.另外,壬醛、 苯乙烯和苯乙酮在青皮垂柳中的质量浓度显著高于苦楝和复叶槭(P<0.05).在以上5种化合物中,有文献报道3-蒈烯和壬醛显示出对光肩星天牛吸引作用,因此推测,3-蒈烯和壬醛可能是对光肩星天牛具有产卵引诱作用的植物源成分.
