摘要
对１９８０—１９８９年河南棉区棉蚜种群动态分析表明，棉蚜为害可分为苗蚜和伏蚜两个时期，根据环境因子（气温、相对湿度、降雨量）和不同危害期，建立了２个模糊预报模型，并取得了较满意的预测效果．
Population dynamics of cotton aphid in cotton fields of Henan Province in 1980-1989 are analyzed in this paper. The results show that the damage period of cotton aphid is at the seedling and flowering-bolting stages of cotton. With consideration of environmental factors (temperature, relative humidity and rainfall) and different damage stages, two fuzzy predicting models are established and good predicting result are obtained.
