摘要
通过对１９８３、１９８４、１９８６、１９８８、１９９４和１９９５年６年棉花铃期以前棉蚜种群数量及其天敌种群数量的系统调查，并采用灰色关联分析法，研究各种天敌对棉蚜种群数量影响程度，得出龟纹瓢虫对棉蚜种群数量影响最大，其次是瓢虫类，第三是蜘蛛类．
The population of Aphis gosspyii and its enemies before cotton boll stage were investigated systematically in 1983,1984,1986,1988,1994 and 1995.Grey relational grade analysis on the influence of natural enemies on population of Aphis gosspyii shows that the influence was in order of Propylaca japonica >coccinellids>araneids.
