Abstract

Agricultural production is primarily constrained by biotic stresses, with insect pests being the most significant contributors. Effective pest management is essential for sustainable crop protection and relies on understanding how plants interact with pests (herbivores), their natural enemies (predators and parasitoids), other plants, and beneficial organisms such as pollinators. These interactions which are also frequently influenced by microorganisms, collectively referred to as multitrophic interactions, play a crucial role in shaping agroecosystems. Recent research highlights that in agricultural systems, multitrophic interactions are primarily mediated by volatile organic compounds and other specialized metabolites through microbial activity. A deeper understanding of these chemically mediated mechanisms in pest, natural enemy and pollinator attraction/repellence, and plant defense priming, offer new opportunities for developing ecologically sustainable pest management strategies. This review aims to synthesize emerging evidence on the role of plant- and microbial-derived specialized metabolites in mediating multitrophic interactions and potential applications for crop protection. It also identifies knowledge gaps and explores how recent advances are shaping the development of innovative crop protection technologies.

化学介导的多营养相互作用及其在作物保护中的作用。

农业生产主要受到生物压力的制约，害虫是最重要的因素。有效的病虫害管理对可持续作物保护至关重要，它依赖于了解植物如何与害虫（食草动物）、它们的天敌（捕食者和拟寄生物）、其他植物以及传粉者等有益生物相互作用。这些相互作用也经常受到微生物的影响，统称为多营养相互作用，在形成农业生态系统方面起着至关重要的作用。最近的研究强调，在农业系统中，多营养相互作用主要是由挥发性有机化合物和其他通过微生物活动的专门代谢物介导的。深入了解这些化学介导的害虫、天敌和传粉媒介吸引/排斥机制以及植物防御启动，为制定生态可持续的害虫管理策略提供了新的机会。本文综述了植物和微生物衍生的特化代谢物在介导多营养相互作用中的作用及其在作物保护中的潜在应用。它还确定了知识差距，并探讨了最近的进展如何影响创新作物保护技术的发展。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
