摘　　要：基于云南松松针粗提物对楚雄腮扁叶蜂雌、雄蜂的明显引诱作用,利用"Y"嗅觉仪测试楚雄腮扁叶蜂对针叶挥发物主要成分的室内趋向行为,分析针叶挥发物对楚雄腮扁叶蜂的引诱活性。结果表明:楚雄腮扁叶蜂雌蜂对(-)-β-蒎烯、月桂烯、β-石竹烯表现出明显的趋向反应,雄蜂则对(+)-α-蒎烯、(-)-β-蒎烯、β-石竹烯的趋向反应显著。(-)-β-蒎烯、月桂烯、β-石竹烯等都诱捕了一定量的楚雄腮扁叶蜂雌蜂;以(-)-β-蒎烯、月桂烯、β-石竹烯、(+)-α-蒎烯、(+)-柠檬烯为引诱剂,诱捕到相较于雌蜂数量较多的雄蜂。Previous researches showed that both females and males of Cephalica chuxiongnica(Hymenoptera: Pamphiliidae) could be attracted by crude extracts of Pinus yunnanensis needles. The taxis responses of C.chuxiongnica to the main volatile constituents of P. yunnanensis needle extract were tested in laboratory with Ytube olfactometer, and the attractive activities of volatile constituents of P. yunnanensis needles extract to the C.chuxiongnica was analyzed. The findings indicated that the females exhibited significant tendency to(-)-β-pinene, myrene and β-caryophyllene, and males showed significant tendency to(+)-α-pinene,(-)-β-pinene and β-caryophyllene.(-)-β-pinene, myrene, and β-caryophyllene all captured a certain amount of females.(-)-β-pinene, myrene, β-caryophyllene,(+)-α-pinene and(+)-limonene captured significantly more males than females.
