摘　　要：通过对玉米整个生长季节内的节肢动物群落调查 ,共发现节肢动物 12目、 39科、 12 3种 ,主要为蜘蛛类、蚜虫类和瓢虫类。玉米田节肢动物群落的相对多度、丰富度、多样性指数和均匀度等群落特征表现出明显的季节动态 ;不同类型田的节肢动物群落组成、群落多样性明显不同。重庆地区小麦 玉米 红苕间套作类型田丰富的节肢动物群落和较大比例的天敌类群 。Based on the investigations on the compositions and structures of the arthropod communities in maize fields, the present paper analyzed the arthropod communities characteristics including the indices species richness (S), evenness (J), Shannon*#*ss index(H′) and the total individual of arthropods (N). There were totally 123 species from 12 orders and 39 families, which mainly composed by natural enemies of ladybirds and spiders. In generally, the S,J′,H′, and N reached its peak value in the tasselling phases of maize. Compared with the different cropping systems, the plant model of wheat intercroping or rotating with maize and sweet_potato can be have higher N and S. Its natural enemies were also richness. The results should provide some scientific bases for the management strategy of maize IPM. -
