摘要

To improve landscape management with a view to promote diversity of natural enemies for controlling pest popu⁃lation to a lower level has become a new approach to bio⁃control of pest in recent years. A review is presented of the resear⁃ches done both at home and abroad in this aspect, with emphasis on introducing principles of regulating agricultural land⁃scape biodiversity and pest bio⁃control. And the landscape⁃management⁃based approaches to bio⁃control of pest in agricul⁃tural landscape is also summarizes. In the end, the problems with and orientation of the approaches in the current scenario of agricultural policies in China are discussed.%应用景观管理促进天敌生物的多样性进而将害虫群落控制在较低水平，成为近些年害虫防治的新途径。在回顾国内外研究的基础上，重点介绍景观管理调节农业景观生物多样性和害虫生物防治的原理，系统总结目前国内外现有农业景观害虫生物防治的景观管理途径和方法。最后，就国内农业政策下推行景观管理、促进害虫防治面临的问题和发展方向进行探讨。
