摘要
集约化农业生产过程中,化学农药所带来的大量环境问题日益引起关注。为减少农药的投入及其所产生的环境负效应,生物防治害虫的方法在国内外得到了更多的关注与发展。生境管理是一种有利于天敌群落发展,而不利于害虫种群增长的保护性生物防治方法,其实质是通过为自然天敌提供诸如花蜜、替代猎物或寄主、躲避不利干扰的庇护所等资源,将农业景观中天敌的害虫控制服务和功能最大化,或者通过构建不适宜害虫取食和繁殖的环境条件起到抑制或阻碍害虫发展的作用。本文在参阅国内外文献的基础上,阐述了生境管理控制害虫的机理,并总结国外生物防治的实践经验以及近些年国内外的相关研究,概括提出田间尺度上害虫生物防治的非作物生境及作物生境的建设和植物配置方法,为通过生境管理提升农业景观中害虫生物防治生态系统服务提供参考。
The negative environmental effect of massive applications of chemical pesticides in intensive agricultural production practices has been a significant global concern. Therefore the rapid development of biological pest control in recent years is directed towards alleviating the negative impacts of intensified modern agricultural practices on the environment. Habitat management is an important conservation biological control approach that creates habitat conditions favorable to natural enemies but unfavorable to agricultural pests. Essentially, habitat management aims to maximize the function of biological control by providing natural enemies with resources （such as additional foods like nectar, alternative preys/hosts, and shelter from adverse conditions）, or to suppress pests by making their habitats unfavorable. The appropriate selection and sound configuration of plants in agricultural landscapes are critical to successful habitat management. In this manuscript, we reviewed the mechanisms of habitat management for pest control. It was concluded that elaborate establishment of non-crop habitats and design of cropping systems were important habitat management approaches for improving biological control. We further proposed potential plant configuration models for biological control of pests in agricultural landscapes in China.
