Ecological studies are increasingly moving towards trait‐based approaches, as the evidence mounts that functions, as opposed to taxonomy, drive ecosystem service delivery. Among ecosystem services, biological control has been somewhat overlooked in functional ecological studies. This is surprising given that, over recent decades, much of biological control research has been focused on identifying the multiple characteristics (traits) of species that influence trophic interactions. These traits are especially well developed for interactions between arthropods and flowers – important for biological control, as floral resources can provide natural enemies with nutritional supplements, which can dramatically increase biological control efficiency. Traits that underpin the biological control potential of a community and that drive the response of arthropods to environmental filters, from local to landscape‐level conditions, are also emerging from recent empirical studies. We present an overview of the traits that have been identified to (i) drive trophic interactions, especially between plants and biological control agents through determining access to floral resources and enhancing longevity and fecundity of natural enemies, (ii) affect the biological control services provided by arthropods, and (iii) limit the response of arthropods to environmental filters, ranging from local management practices to landscape‐level simplification. We use this review as a platform to outline opportunities and guidelines for future trait‐based studies focused on the enhancement of biological control services.

通过多营养性状相互作用管理生物防治服务：在地方和景观尺度上实施的审查和指南

生态研究正越来越多地转向基于特征的方法，因为越来越多的证据表明，与分类学相反，功能驱动生态系统服务的提供。在生态系统服务中，生物控制在功能生态学研究中有些被忽视。这是令人惊讶的，因为近几十年来，大部分生物控制研究都集中在确定影响营养相互作用的物种的多种特征（性状）上。这些性状特别适合节肢动物和花卉之间的相互作用——对生物控制很重要，因为花卉资源可以为天敌提供营养补充，从而可以显着提高生物控制效率。最近的实证研究也出现了支撑社区生物控制潜力并推动节肢动物对环境过滤器（从局部到景观水平条件）做出反应的特征。我们概述了已确定的特征，以 (i) 驱动营养相互作用，特别是通过确定花卉资源的获取途径和提高天敌的寿命和繁殖力，特别是植物和生物防治剂之间的相互作用，(ii) 影响所提供的生物防治服务由节肢动物，以及 (iii) 限制节肢动物对环境过滤器的反应，从本地管理实践到景观水平的简化。
