摘　　要：利用气相色谱-质谱联用仪对水蒸气蒸馏法提取的油橄榄、板栗和杨梅树叶的挥发油进行了分析,在3种树叶挥发性提取物中分别检测出了58,40和43个成分.利用"Y"型嗅觉仪测试了陈齿爪鳃金龟对3种树叶挥发油的趋向反应.在单项选择试验中,陈齿爪鳃金龟雌、雄虫对油橄榄和板栗树叶挥发物表现出明显的趋向反应,且雌虫的趋向反应率大于雄虫;陈齿爪鳃金龟对杨梅树叶挥发物则表现出明显的忌避反应.在双项选择试验中,油橄榄与板栗和杨梅相比,陈齿爪鳃金龟更趋向于油橄榄树叶挥发物;而板栗与杨梅相比,则更趋向于板栗树叶挥发物.Volatile oils of the leaves of Olea europaea, Castanea mollissima and Myrica rubra were extracted by steam distillation and analysed by GC-MS, their attraction activities to Holotrichia cheni were test- ed in a Y-tube olfactometer. A total of 58, 40 and 43 components were detected from O. europaea, C. mollissima and M. rubra, respectively. In a one-way choice experiment, male and female adults of H. cheni expressed statistically significant taxis responses to volatiles of O. europaea and C. mollissima, and the taxis responses of the females to both volatile oils were higher than those of the males. However, the leaf volatiles of M. rubra were repellent to the scarab beetles. In a two-way choice experiment, H. cheni beetles showed greater taxis to the volatiles of O. europaea than to those of C. mollissima and M. rubra, and greater taxis to the volatiles of C. mollissima than to those of M. rubra.
