Plant volatiles are used not only by herbivorous insects to find their host plants, but also by the natural enemies of the herbivores to find their prey. There is also increasing evidence that plant volatiles, in addition to species-specific pheromones, help these insects to find mating partners. Plant structures such as flowers, fruit, and leaves are frequently rendezvous sites for mate-seeking insects. Here we propose that the combined use of plant volatiles and pheromones can efficiently guide insects to these sites, where they will have access to both mates and food. This notion is supported by the fact that plant volatiles can stimulate the release of sex pheromones and can render various insects more receptive to potential mates.

食草昆虫不仅利用植物挥发物寻找寄主植物，而且食草动物的天敌也利用植物挥发物寻找猎物。越来越多的证据表明，除特定物种的信息素外，植物挥发物还有助于这些昆虫寻找交配伙伴。花朵，果实和树叶等植物结构经常是寻找昆虫伴侣的聚会场所。在这里，我们建议将植物挥发物和信息素的组合使用可以有效地将昆虫引导到这些地点，使它们能够接触到伴侣和食物。植物挥发物可以刺激性信息素的释放，并使各种昆虫更容易接受潜在的配偶，这一事实为这一观点提供了支持。
