摘　　要：麦长管蚜Sitobion avenae(Fabricius)是我国乃至世界麦区的重大害虫,不仅能传播病毒病,而且还严重影响小麦的产量和品质。油菜Brassica napus是我国黄淮海麦区非常重要的与小麦间作的作物。本文主要研究了小麦与油菜间作对麦田主要害虫——麦长管蚜的优势天敌的生态效应。通过运用天敌总量、物种丰富度(S)、申农指数(Shannon's index,H′)、均匀度指数(E)作为多样性分析的综合指标,分析了不同处理方式对蚜虫天敌群落的影响。麦油间作处理对天敌总量、丰富度、多样性、均匀度都有不同程度的影响。The English green aphid Sitobion avenae is the major pest of wheat in China and many other countries. It is not only a vector of plant virus diseases,but also leads heavy damage to wheat. Oilseed rape Brassica napus is very important intercropping crop of wheat in Huang-huai-hai wheat region. This paper investigated the ecological effects of wheat-oilseed rape intercropping to M. avenae and its natural enemies. We investigated the total number,species richness,index of diversity and evenness of natural enemy in different treatment plots. The results showed that the total number,species richness of natural enemy in wheat-oilseed rape intercropping blocks were significantly higher than those in the monoculture fields.
