中文摘要： 【目的】 为了探明对云斑天牛Batocera lineolata Chevrolat成虫具有行为导向的寄主植物挥发物对成虫行为反应的影响。【方法】 采用触角电位(EAG)和“Y”型嗅觉仪技术，测定云斑天牛成虫(未交配雌虫、未交配雄虫、已交配雌虫)对10种寄主植物挥发物的电生理和行为反应。【结果】 所选化合物在特定浓度下，均能引起云斑天牛成虫较为明显的EAG反应，浓度为100 μg/μL时，云斑天牛成虫对所测试的植物挥发物的EAG反应最强，其中未交配雌、雄及已交配雌虫对(Z)-3-己烯-1-醇的EAG反应相对值均为最大，分别达2.35、2.31和2.22。行为反应生测中，(Z)-3-己烯-1-醇对未交配雌、雄虫可产生明显的引诱作用，芳樟醇则对两者具有明显的趋避作用，而已交配雌虫对所有化合物均无明显趋性。【结论】 试验结果可为开发对其有效的林间引诱剂提供一定的理论依据。
英文摘要： [Objectives] To verify the effects of the host plant volatiles on the behavior of adult Batocera lineolata Chevrolat. [Methods] The electroantennogram and behavioral responses of the B. lineolata adults (unmated females, unmated males and mated females) to 10 kinds of plant volatiles were tested with EAG and a Y-tube olfactometer. [Results] The ten test chemicals induced clear EAG responses. B. lineolata adults had the strongest EAG responses to the tested plant volatiles when the concentration was 100 μg/μL. The EAG responses values of unmated female and male and mated female B. lineolata adults to (Z)-3-Hexen-1-ol were the highest, being 2.35, 2.31 and 2.22, respectively. As for behavioral responses, unmated female and male B. lineolata adults were strongly attracted to (Z)-3-Hexen-1-ol, whereas Linalool had an obvious repellent effect on unmated female and male B. lineolata adults. None of the compounds tested were attractive to mated female B. lineolata adults. [Conclusion] The results provide some theoretical basis for the development of effective attractants for B. lineolata.
