| 摘 要： | 研究麦田蚜虫及其天敌群落的结构特征,结果表明:麦田蚜虫及其天敌群落主要由麦长管蚜、禾谷缢管蚜和麦二叉蚜3种麦蚜以及12种天敌昆虫组成,天敌中以蚜茧蜂数量最多。麦蚜和天敌的演替可以划分为3个阶段,第1阶段的麦蚜和天敌数量较少,没有必要防治蚜虫;第2阶段,麦蚜数量达到顶峰,群落处于不稳定状态;第3阶段,群落处于衰退阶段。

| Abstract: | The community structure characteristics of wheat aphids and their netural enemies were studied,the result showed that:wheat aphids and their natural enemies′ community were composed of Macrosiphum avenae F,Rhopalosiphum padi L,Schizaphis graminum Rond and other 12 kinds of natural enemies.The numbers of Aphidiidaes were the largest among these natural enemies.The succession process of aphids and natural enemies could be divided into three phases.The first stage,The numbers of aphids and natural enemies were small and aphids control was not necessary;The second stage,the numbers of aphids reached a peak,the community was in an unstable state;The community at the third phase was in a recession. |
