植物挥发物以多种方式介导植物、植食性节肢动物和植食性天敌之间的三重营养相互作用。这些挥发物分为两类：食草动物诱导的植物挥发物（HIPVs）和组成型释放的植物挥发物。食草动物和食肉动物使用这些植物挥发物作为有效觅食的信息。因此，可以构建基于HIPVs多功能方面的信息化学网。本文综述了植物挥发物在单一三重营养系统中的生态功能以及两个三重营养系统耦合对植物挥发物功能的影响，重点介绍了三重营养系统中的信息化学网络。此外，还对吸引特定天敌的HIPV的应用前景进行了讨论。
关键概念：
为了应对食草动物引起的损害，植物会释放所谓的“食草动物诱导的植物挥发物（HIPV）”，这些挥发物不是植物自然释放的，或者在许多情况下仅以痕量释放。
HIPV的混合物根据植物的类型而变化：食草动物和食肉动物。
HIPV和组成性释放的植物挥发物分别和/或同时被食草动物和食肉动物使用，以形成信息化学网。
将两个三营养系统耦合在同一植物上，对每个三营养系统的信息化学网产生积极或消极的影响。
HIPVs将成为生物防治的新工具。这需要对目标农业生态系统进行全面研究。

Plant volatiles mediate tritrophic interactions between plants, herbivorous arthropods and the carnivorous natural enemies of herbivores in various ways. These volatiles are classified into two categories: herbivore-induced plant volatiles (HIPVs) and constitutively emitted plant volatiles. Herbivores and carnivores use these plant volatiles as information for effective foraging. Consequently, infochemical webs based on the multifunctional aspects of HIPVs can be constructed. This article reviews the ecological function of plant volatiles in a single tritrophic system and the effects of the coupling of two tritrophic systems on the function of plant volatiles with emphasis on the infochemical webs in tritrophic systems. Furthermore, prospects for the application of HIPVs that attract specific natural enemies are discussed.
Key Concepts:
In response to herbivore-induced damage, plants emit the so-called ‘herbivore-induced plant volatiles (HIPVs)’ that are not naturally emitted from plants or in many cases emitted only in trace amounts.
The mixtures of HIPVs vary according to the type of plants: herbivores and carnivores.
Both HIPVs and constitutively emitted plant volatiles are separately and/or simultaneously used by both herbivores and carnivores to form infochemical webs.
Coupling the two tritrophic systems on the same plants affects the infochemical webs of each tritrophic system either positively or negatively.
HIPVs would be a new tool for biological control. This requires comprehensive studies on the target agroecosystem.
