The sexual behavior of phytophagous insects is often integrated in a variety of ways with their host plants. This integration may be manifested as effects or influences of host plants on insect physiology and behavior, including sex pheromone communication, that reflect strategies by insects to optimize mating and reproduction. Certain insects sequester or otherwise acquire host plant compounds and use them as sex pheromones or sex pheromone precursors. Other insects produce or release sex pheromones in response to particular host plant cues. Chemicals from host plants often synergize or otherwise enhance insect responses to sex pheromones. By these means, host plants may be used by insects to regulate or mediate sexual communication. For many species of insects, host plant influences on insect sex pheromone communication may be important aspects of the formation of feeding and mating aggregations, of insect strategies to locate both hosts and mates, of behavioral reproductive isolation among sibling species, and of the regulation of reproduction to coincide with the availability of food and oviposition sites. Knowledge of these relationships is critical to understanding many different areas of the behavioral ecology of plant-feeding insects.
植食性昆虫的性行为通常以多种方式与它们的寄主植物相互关联。这种关联可能表现为寄主植物对昆虫生理和行为的影响,包括性信息素通讯,这反映了昆虫优化交配和繁殖的策略。某些昆虫会隔离或以其他方式获取寄主植物的化合物,并将其用作性信息素或性信息素前体。其他昆虫则会根据特定的寄主植物线索产生或释放性信息素。寄主植物的化学物质通常会协同作用或以其他方式增强昆虫对性信息素的反应。通过这些方式,昆虫可以利用寄主植物来调节或介导性通讯。对于许多昆虫物种来说,寄主植物对昆虫性信息素通讯的影响可能是形成取食和交配聚集、昆虫定位寄主和配偶的策略、近缘物种间行为生殖隔离以及使繁殖与食物和产卵场所的可利用性相匹配的繁殖调节等方面重要的因素。了解这些关系对于理解植食性昆虫行为生态学的许多不同领域至关重要。
