Uninfested plants emit only trace quantities of volatiles (constitutively emitted plant volatiles). In contrast, some plants emit relatively large quantities of volatiles in response to herbivory (herbivory-Induced plant volatiles: HIPVs). Organisms belonging to different trophic levels use plant volatiles in context-dependent manners; consequently, volatiles can be adaptive, non-adaptive, or maladaptive to the emitter plants. In this review, we focus on the multifunctional aspects of HIPVs, which vary qualitatively and quantitatively in emitting plant species and infesting herbivore species, in plant-carnivore interactions, plant-herbivore interactions, and plant-omnivore interactions. Additionally, we review the evidence of plant-plant communication and its effects on tritrophic interactions involving plants, herbivores, and carnivores. Prospects on interactions mediated by plant volatiles induced by herbivorous arthropods are discussed.
未受侵害的植物仅释放痕量的挥发物（组成性释放的植物挥发物）。相比之下，一些植物在受到食草动物侵害时会释放相对大量的挥发物（食草动物诱导的植物挥发物：HIPVs）。属于不同营养级的生物以依赖于上下文的方式利用植物挥发物；因此，挥发物对释放植物可能是适应性的、非适应性的或不适应的。在这篇综述中，我们重点关注 HIPVs 的多功能性方面，这些方面在释放植物物种和侵害食草动物物种、植物-肉食者相互作用、植物-食草动物相互作用以及植物-杂食者相互作用中在质量和数量上有所不同。此外，我们还回顾了植物间通讯的证据及其对涉及植物、食草动物和肉食动物的三营养级相互作用的影响。讨论了由食草性节肢动物诱导的植物挥发物介导的相互作用的前景。
