| 摘 要： | 作者根据新疆塔城麦田的系统调查资料,探讨了麦双尾蚜Diuraphis noaxia Mordvilko及其天敌种群动态,应用相关分析和通径分析方法,寻找影响麦双尾蚜数量变动的关键天敌种类。结果表明,麦双尾蚜在麦田为聚集分布;影响冬麦田麦双尾蚜数量的天敌主要有七星瓢虫Coccinella septempunctata、意大利豹蛛Pardosa italica等;影响春麦田麦双尾蚜数量的天敌主要有白足蚜小蜂Aphelinus albipodus、燕麦蚜茧蜂Aphidius picipes和环足灰斑腹蝇Leucopis annulipes等。

| Abstract: | Based on the field investigation in Tacheng, Xinjiang Uygur Autonomous Region 1991 and 1994, the population dynamics of Diuraphis noxia Mordvilko and its natural enemies were studied. The results of correlation analysis and path analysis indicated Coccinella septempunctata and Pardosa italica were key natural enemies affecting the pupulation dynamics of D. noxia in winter wheat field, and Aphelinus albipodus, Aphid-ius picicpes and Leucopis annulipes were key natural enemies in spring wheat field. |
