摘　　要：研究了棉盲蝽在转基因抗虫棉药剂防治与不使用药剂防治上的发生差异,及棉田周边杂草上棉盲蝽发生动态,结果:①不防治类型棉田各棉盲蝽百株虫口总发生量为879头,其中:中黑盲蝽274头,绿盲蝽189头,杂毛合垫盲蝽407头,赣棉淡盲蝽9头,虫种比依次为:31∶22∶46∶1,杂毛合垫盲蝽为优势种;②常规防治类型棉田各棉盲蝽百株虫口总发生量为588头,其中:中黑盲蝽371头,绿盲蝽104头,杂毛合垫盲蝽94头,烟盲蝽17头,赣棉淡盲蝽2头,虫种比依次为:63∶18∶16∶3∶0.3,中黑盲蝽为优势种。9月22日～11月2日棉田边盲蝽杂草寄主和虫口发生量:赣棉淡盲蝽杂草寄主有18种,虫口发生量779头,排位第一;绿盲蝽杂草寄主14种,虫口发生量180头,排第二位;异须单突盲蝽杂草寄主5种,虫口发生量104头,排第三位;其他几种棉盲蝽杂草寄主少发生量小,以小飞蓬杂草发生棉盲蝽种类最多,达6种。The author studied the occurrence of cotton lygus in transgenic insect - resistant cotton fields （ conducting chemical control or not） and their surrounding weeds. The results showed that： ① in the cotton fields without chemical control, the total quantity of cotton lygus per 100 plants was 879 heads, including 274 Adelphocoris suturalis, 189 Apolygus lucorurns, 407 Orthotylus flavosparsus and 9 Creontiades bipuartctatus, the population ratio of the four species was 31：22： 46： 1, and Orthotylus flavosparsus was the dominant species among them; ② in the conventional control cotton fields, the total quantity of cotton lygus in every one hundred cotton plants was 588 heads, including 371 Adelphoeoris suturalis, 104 Apolygus lucorum, 94 Orthotylus flavosparsus, 17 Gyrtopeltis tenuis and 2 Creontiades bipuanctatus, the population ratio of the five species was 63： 18： 16： 3： 0.3, and Adelphocoris su- turalis was the dominant species among them. From September 22 to November 2, the surrounding weed host species of Creontiades bipuanctatus was the most （18 species）, and its total quantity in these hosts was 779 heads; Adelphocoris suturalis was the second, and its weed host species and total quantity were 14 species and 180 heads respectively; Opuna annalata was the third, whose weed host species and total quantity were 5 species and 104 heads respectively ; the weed host species and total quantity of the other cotton lygus species were very few; six species of cotton lygus occurred in Conyza canadensis （L.） , which was the largest number.
