摘　　要：盲蝽目前在棉田为害十分猖獗,通过研究盲蝽的生活习性、寄主植物和为害特点,并结合我国目前棉花生产的现状和盲蝽对棉田为害的实际情况,分析了棉田盲蝽为害日益严重的成因,初步得出由于防治效果欠佳,抗性迅速增加;种植结构调整,寄主植物增多;种植密度增加,生存环境优化等客观原因以外,认为目前种植的转Bt基因抗虫棉改变了盲蝽在生态系统中的生态位,并且可能由于转Bt基因的缘故使得棉花的生理代谢发生改变,使得转Bt基因抗虫棉对盲蝽具有更强的诱惑力。Apolygus lucorum Meyer Dtir,as the current damage runs rampant in the cotton fields, the paper combines current status of cotton production and the actual situation of infestation in cotton field to study the habits of the bugs, host plants and damage characteristics and to analyse the causes and control strategies of growing bugs damage. Preliminary results obtained that because of poor control, resistance increased rapidly; planting structure adjustment, the host plant increased; planting density increased constantly, habitat optimization. Excepted the objective reasons, that currently under cultivation of Bt cotton, changed the niche of Apolygus lucorum in the ecosystem, and due to transgenic Bt cotton metabolism changes, and made the transgenic Bt cotton a stronger temptation on the bugs.
