【摘要】 兴安落叶松球果挥发性物质中主要为单萜类物质，１９９８年用几种主要的单萜类物质为气味源，利用四臂嗅觉仪对落叶松球果花蝇进行了嗅觉反应试验。结果表明，根据被害球果挥发性物质的自然比例配制的α－蒎烯、β－蒎烯、月桂烯、罗勒烯等４种物质的混合液对球果花蝇表现为诱引作用，而球果花蝇对其它某些气味物质表现为忘避反应。挥发性物质的林间喷洒试验结果与嗅觉反应试验结果一致。讨论了单萜类物质在球果花蝇对寄主定位和产卵过程中的诱引或驱避作用。更多还原

【Abstract】 Several main monoterpenes and their combinations from Dahurian larch (Larix gmelinii Rupr.) cones were used as odor sources in olfactory experiment to test the responses of larch cone flies (Strobilomyia spp. ) in 1998. The results revealed that blend of α -pinene, β-pinene, laurene and β- ocimene in a ratio close to its volatile profile of damaged cones achieved the best response while certain odors showed repellent tendency to cone flies. Field spraying Dahurian larch cones with some of its volatile components had mixed results but support the olfactory testing results. The role of monoterpenes in cone fly host location and oviposition in terms of attractive signals or repellent is discussed.更多还原
