摘要
通过对１９９３～１９９６年两种麦蚜种群数量及其天敌数量的系统调查，并采用灰色关联分析法，研究各种天敌对两种麦蚜种群数量的影响程度，得出对麦长管蚜种群数量影响最大的是龟纹瓢虫、蚜茧蜂和食蚜蝇；对麦二叉蚜种群数量影响最大的是草间小黑蛛，其次是龟纹瓢虫．
After a systematic investigation on the populations of wheat aphids, greenbugs and their natural enemies during 1993～1996, the grey association analysis was made and showed that Propylaca japonica, Aphididae and Syrphidae were the natural enemies most greatly influenced the population of wheat aphid, while Erigonidium graminicola influenced the population of greenbug most greatly, and Propylaca japonica secondly.
