摘　　要：江西转基因抗虫棉苗期发生绿盲蝽、中黑盲蝽、杂毛合垫盲蝽3种棉盲蝽,以绿盲蝽和中黑盲蝽为主要发生种,绿盲蝽与中黑盲蝽种群为1.54∶1,绿盲蝽为优势种,但具体在各棉苗床上这些盲蝽虫口发生优势差别与附近杂草群落种类有关。棉盲蝽在苗床上虫口增长与附近杂草花期消退、除草剂使用、棉苗移栽晚苗龄大有关。There were three species of cotton plant bugs in the seedling period of Jiangxi provincial transgenic insect - resistant cotton, and they were Lygus lucorum, Adelphocoris suturalis and Orthotylus flavosparsus. Lygus lucorum and Adelphocoris suturalis were the two main species, the ratio of their population density was 1.54： 1, and Lygus lucorum was the dominant species. The difference in the population density on the cotton seedbed among different species of cotton plant bugs was related to the kinds of weed communities nearby. The population growth of cotton plant bugs on the seedbed was greatly influenced by the following factors ： regression of flowering stage of the weeds nearby, application of herbicides, and late transplanting of cotton seedlings.
