农田生态系统的多样化和作物生境的多样性有利于天敌的生存与增殖，从而提高对害虫的自然控制作用。捕食性天敌是影响作物害虫种群动态的重要因子。在捕食性天敌中，蜘蛛的种类和数量非常丰富，是农田生态系统中节肢动物群落的优势类群，其群落结构与功能的特性直接制约着害虫
Diversification of farmland ecosystems and the diversity of crop habitats favor the survival and proliferation of natural enemies, thereby enhancing the natural control of pests. Predatory enemies are important factors that affect the population dynamics of crop pests. Among the predatory natural enemies, spiders are very rich in species and numbers and are the dominant groups of arthropod communities in farmland ecosystems. Their characteristics of community structure and function directly constrain pests
