Keyword:  新疆 麦蚜 生态位;
Abstract: 利用生态位理论, 对新疆塔城、伊犁两地区麦田的麦双尾蚜Diuraphis noxia (Mordvilko) 、麦二叉蚜Shizaphisgraminum (Rondani) 、麦长管蚜Sitobion avenae(F.) 和禾谷缢管蚜Rhopalosiphum padi(L.) 等4 种麦蚜生态位宽度和重叠度进行了估测和分析。在塔城麦田麦双尾蚜时间生态位宽度最大, 麦双尾蚜和麦二叉蚜时间生态位重叠最大, 竞争激烈。伊犁麦田禾谷缢管蚜时间生态位宽度最大, 麦二叉蚜在空间生态位和时空二维生态位上均占有明显的优势, 麦长管蚜和麦双尾蚜的时间生态位重叠最大, 麦长管蚜和麦二叉蚜在空间生态位和时空生态位重叠最大。
