Abstract

Biological control is affected by the composition of landscapes surrounding agricultural fields. Natural enemy communities are typically more diverse, and effective at providing biological control services, in complex compared to simple landscapes. However, the use of simple metrics to characterize landscapes, such as the proportion of agricultural habitat, obscures the mechanisms by which landscapes affect biological control. Studies that evaluate the overall complexity of agricultural landscapes, and their temporal variability, allow for a greater mechanistic understanding of the impacts of landscape composition on biological control. From an applied perspective, decision support systems, which deliver real-time information about pest and natural enemy populations, are an effective tool for delivering recommendations to strengthen biological control across space and time.

摘要

生物防治受到农业用地周围景观组成的影响。与简单的景观相比，在复杂的景观中，天敌群落通常更加多样化，并且在提供生物防治服务方面更加有效。然而，使用简单的指标来描述景观，例如农业生境的比例，掩盖了景观影响生物防治的机制。评估农业景观整体复杂性及其时间可变性的研究，可以更深入地了解景观组成对生物防治的影响的机制。从应用的角度来看，决策支持系统可以实时提供关于害虫和天敌种群的信息，是一种有效的工具，可以在空间和时间上提供加强生物防治的建议。
