寄主植物防御植食性昆虫策略及其介导的昆虫间互作研究进展OA

Host plants and herbivorous insects engage in complex interactions characterized by co-evolution.Current research on plant-insect interactions predominantly focuses on single pest species and their host plants.However,under natural conditions,plants are often simultaneously attacked by multiple insect pests.Therefore,in-depth analysis of host plant defense strategies under multiple pest infestations and the insect interactions mediated by these strategies is crucial for uncovering plant-insect co-evolutionary dynamics and optimizing integrated pest management strategies.Although many studies have reported the effects of multiple pest infestations on host plants and interspecific interactions among insects,there remains a lack of systematic review and summary of research progress and experimental methods in this field.Therefore,this article systematically elaborates on four aspects:host plant defense strategies,plant-mediated regulation of interspecific insect relationships,counter-defense strategies of herbivorous insects,and research methods and technologies for plant-insect interactions.In addition,future research directions are discussed.The aim of this review is to offer a theoretical foundation for further investigation into plant-insect and insect-insect interactions and for establishing ecological regulation systems based on plant insect resistance.
