摘　　要：昆虫和植物是自然界生物类群中重要的组成部分,在长期进化的过程中形成了复杂的相互作用关系,如植物进化出了复杂的防御策略来抵御昆虫为害,同时,昆虫为了获取更多的生存资源也进化出了更多的适生方式。因此,分析和了解昆虫与寄主植物相互适应的研究进展对害虫的有效防治和抗虫植物的培育具有重要作用。在昆虫与寄主植物互作的研究中,植食性昆虫的口腔分泌物(唾液或反刍液)、卵分泌物、肠道合成物及微生物等作为连接昆虫和植物的中间媒介,其有效成分不仅起着诱导或增强植物防御的作用,而且部分还具有抑制或削弱植物防御的功能,因此,按有效成分发挥的作用,植食性昆虫的口腔分泌物主要可分为激发子和效应子。本文从昆虫分泌物的角度介绍了昆虫钙结合蛋白类、酶类和毒液蛋白类等效应子与脂肪酸氨基酸共轭物类、多肽类和酶类等激发子及其介导植物防御的主要方式,明确了植食性昆虫适应寄主植物防御的不同策略,不仅有助于对昆虫和植物两者互作机制的深入解析,而且为绿色有效防治害虫和植物抗性品种的选育提供新的思路。Insects and plants are important components of biological community in nature and have evolved complex interactions during the long-term evolution process.For example,plants have evolved complex defense strategies to resist insect damage,meanwhile,insects have also evolved more adaptive ways to get more resources for survival.Therefore,studies that focus on the mutual adaptation between insects and host plants are important for effective pest control and cultivation of insect-resistant plants.In the study of the interactions between insects and host plants,the effective components of the oral secretions from herbivorous insects such as saliva or regurgitant liquid,egg secretions,intestinal compounds and microorganisms as the intermediate media to connect insects and plants not only play important roles in inducing or enhancing plant defense,but also have some functions of inhibiting or weakening plant defense.Therefore,according to the role played by the effective components,the oral secretions from herbivorous insects can be divided into elicitors and effectors.In this review article,we introduced the main types of insect effectors including calcium-binding proteins,enzymes and venom proteins,and elicitors including fatty acid amino acid conjugates,polypeptides and enzymes,and the main ways of mediating plant defense from the perspective of insect secretion,clarified the different strategies of herbivorous insects adapting to plant defense,which not only contribute to the in-depth analysis of the interaction mechanism between insects and plants,but also provide new ideas for green and effective pest control and breeding of plant resistant varieties.
