植物释放不同的混合物的草食动物诱导的植物挥发物（HIPVs）后，草食动物的攻击。HIPV长期以来一直被认为会影响食草动物和天敌的行为。此外，HIPV可以作为诱导或引发植物防御的生理调节剂。最近的研究表明，HIPVs的调节能力可能会扩展到食草动物的免疫：暴露于HIPVs的食草动物可能会变得对寄生虫和病原体更具抵抗力或易感性。虽然HIPV介导的植物防御调节机制正在解开，草食动物免疫调节的机制尚不清楚。到目前为止的证据表明，高度的上下文依赖。在这里，我们回顾HIPVs调节植物防御和草食动物免疫的机制。我们解决知识的主要差距，并讨论未来的机制研究方向，以促进利用HIPVs的生物防治害虫的监管能力的努力。
Plants release distinct blends of herbivore-induced plant volatiles (HIPVs) upon herbivore attack. HIPVs have long been known to influence the behavior of herbivores and natural enemies. In addition, HIPVs can act as physiological regulators that induce or prime plant defenses. Recent work indicates that the regulatory capacity of HIPVs may extend to herbivore immunity: herbivores that are exposed to HIPVs can become more resistant or susceptible to parasitoids and pathogens. While the mechanisms of HIPV-mediated plant defense regulation are being unraveled, the mechanisms underlying the regulation of herbivore immunity are unclear. Evidence so far suggests a high degree of context dependency. Here, we review the mechanisms by which HIPVs regulate plant defense and herbivore immunity. We address major gaps of knowledge and discuss directions for future mechanistic research to facilitate efforts to use the regulatory capacity of HIPVs for the biological control of insect pests.
