Forest pests can cause massive ecological and economic damage worldwide. Ecologically sound solutions to diminish forest insect pest impacts include the use of their natural enemies, such as predators and parasitoids, as well as entomopathogenic fungi, bacteria or viruses. Phytochemical compounds mediate most interactions between these organisms, but knowledge of such chemically mediated multitrophic relationships is still at its infancy for forest systems, particularly when compared to agricultural systems. Here, we highlight the main gaps in how phytochemicals of forest trees facilitate or interfere with trophic interactions between trees, insect herbivores, and interacting organisms including predators, parasitoids and microbes. We propose future avenues of research on phytochemical-based biocontrol of forest pests taking into account the characteristics of trees and forests.
森林害虫会在全球范围内造成巨大的生态和经济损失。减少森林虫害影响的生态合理解决方案包括利用其自然天敌，如捕食者和寄生蜂，以及昆虫病原真菌、细菌或病毒。化学生态化合物介导了这些生物之间的大多数相互作用，但与农业系统相比，森林系统中这种化学介导的多营养关系的知识仍处于起步阶段。在这里，我们强调了森林树木的化学生物在多大程度上促进或干扰树木、昆虫食草动物以及包括捕食者、寄生蜂和微生物在内的相互作用生物之间的营养相互作用方面的主要差距。我们提出了基于植物化学物质的森林害虫生物防治的未来研究途径，同时考虑到树木和森林的特点。
