| 摘 要： | １９８９年，１９９０年进行了大豆蚜虫田间种群数量变动及其对大豆发育、产量的影响试验。试验田设大豆蚜虫自然发生的危害区和用１０％增效乐果防治蚜虫危害的控制区。危害区的田间蚜虫，１９８９年发生早蚜是升快，６月１５百株蚜量超过万头，发生盛期持续时间长达４９０天；１９９０年比１９８９年发生稍晚，盛期持续时间短，危害区的大豆植株明显表现叶片卷缩，节间缩短、茎矮化。控制区植株高度均高于危害区。１９８９年 ２０

| Abstract: | Study on effect of population dynamics of soybean aphid on soybean growth and seed yield was conducted in the field in 1989 and 1990.The results indicated that the effect of soybean aphid on soybean seed yield wes obvious.The yield reduction caused by soybean aphid was 27.8% and plant height had decreased by 20.2cm as compared with control in 1989. About June 25, when population of aphid on hundred-soybean plants was over ten thousands and the plants damaged by aphid were more than 90% it was considered to be the optimum peroid for control. |
