摘　　要：研究结果表明,在低、中、高3种施氮肥水平处理条件下,随着棉田施氮量的增加,转Bt基因棉棉铃虫落卵量和幼虫数量增加,棉苗蚜、伏蚜、棉叶螨种群数量减少,但差异均未达显著水平.The results of study show that under the 3 conditions of low, medium and high level of nitrogen fertilization the number of accumulated eggs and larvae of cotton bollworm in transgenic Bt cotton increased with the increase in level of nitrogen fertilization, and the number of seedling Aphids, summer Aphids and Red spider mites all decreased,but the difference was not significant.
