Arthropod predators and parasitoids attack crop pests, providing a valuable ecosystem service. The amount of noncrop habitat surrounding crop fields influences pest suppression, but synthesis of new studies suggests that the spatial configuration of crops and other habitats is similarly important. Natural enemies are often more abundant in fine-grained agricultural landscapes comprising smaller patches and can increase or decrease with the connectivity of crop fields to other habitats. Partitioning organisms by traits has emerged as a promising way to predict the strength and direction of these effects. Furthermore, our ability to predict configurational effects will depend on understanding the potential for indirect effects among trophic levels and the relationship between arthropod dispersal capability and the spatial scale of underlying landscape structure.

预测景观配置对农业害虫抑制的影响。

节肢动物的食肉动物和寄生生物攻击农作物的害虫，提供了宝贵的生态系统服务。农田周围非作物生境的数量会影响有害生物的抑制，但是最新研究综合表明，作物和其他生境的空间结构也同样重要。在具有较小斑块的细粒度农业景观中，天敌通常更为丰富，并且随着耕地与其他生境的连通性而增加或减少。按特征对生物进行分区已成为预测这些效应的强度和方向的一种有前途的方法。此外，
