Over the past few years, our knowledge of how ecological interactions shape the structure and dynamics of natural communities has rapidly advanced. Plant chemical traits play key roles in these processes because they mediate a diverse range of direct and indirect interactions in a community-wide context. Many chemically mediated interactions have been extensively studied in industrial cropping systems, and thus have focused on simplified, pairwise and linear interactions that rarely incorporate a community perspective. A contrasting approach considers the agroecosystem as a functioning whole, in which food production occurs. It offers an opportunity to better understand how plant chemical traits mediate complex interactions which can enhance or hinder ecosystem functions. In this paper, we argue that studying chemically mediated interactions in agroecosystems is essential to comprehend how agroecosystem services emerge and how they can be guaranteed through ecosystem management. First, we discuss how plant chemical traits affect and are affected by ecological interactions. We then explore research questions and future directions on how studying chemical mediation in complex agroecosystems can help us understand the emergence and management of ecosystem services, specifically biological control and pollination.
在过去几年中，我们对生态相互作用如何塑造自然群落的结构和动态的认识迅速进步。植物化学性状在这些过程中发挥着关键作用，因为它们在群落范围内介导了各种各样的直接和间接相互作用。许多化学介导的相互作用已在工业种植系统中得到广泛研究，因此重点关注简化的、成对的和线性的相互作用，这些相互作用很少纳入群落视角。一种截然不同的方法将农业生态系统视为一个运作的整体，其中进行粮食生产。它提供了一个机会，以更好地理解植物化学性状如何介导复杂的相互作用，这些相互作用可以增强或阻碍生态系统功能。在本文中，我们认为研究农业生态系统中化学介导的相互作用对于理解农业生态系统服务如何产生以及如何通过生态系统管理来保障这些服务至关重要。首先，我们讨论植物化学性状如何影响生态相互作用以及如何受到生态相互作用的影响。然后，我们探讨关于研究复杂农业生态系统中的化学介导作用如何帮助我们理解生态系统服务（特别是生物防治和授粉）的出现和管理的研究问题及未来方向。
