在大量的研究结果表明,植物释放的挥发性次生物质对植食性昆虫有引诱或驱避作用。植物的挥发性物质可诱导昆虫产生寄主定向行为、交配行为、产卵地点的选择行为、取食、聚集,逃避和传粉行为等,昆虫则通过特定的化学感受器官识别和接受来自环境中的化学信息,为适应环境和寻找生存最佳条件作出相应的行为反应。植物挥发性物质的成分和相对比例在不同的属、种及无性系之间均有不同程度的差异。丽江球果花蝇是云南省新发现的喜马拉雅落叶松,球果及种子的主要害虫,危害较为严重,但对同一立地条件
In a large number of studies, it has been shown that volatile secondary metabolites released from plants induce or repel herbivores. Volatiles from plants induce insect-induced host-directed behavior, mating behavior, selection behavior at spawning sites, feeding, aggregation, escape and pollination behavior, while insects recognize and accept chemicals from the environment through specific chemical receptors Information, in order to adapt to the environment and find the best conditions for survival to make the appropriate behavior response. The composition and relative proportions of volatile compounds in plants vary among different genera, species and clones. Lijiang Drosophila melanogaster is a newly discovered major Himalayan larch, coniferous and seed pest in Yunnan Province. The damage is more serious, but the same site conditions
