摘　　要：2004—2006年，采用面上普查的方法，初步查明盐城农区绿盲蝽的寄主植物为28科100种，中黑盲蝽为29科105种。通过系统调查结合室内饲养校正，明确了两种棉盲蝽在棉田内，全年有3次迁入高峰和1次迁出高峰。棉盲蝽具有强烈的趋嫩、趋绿和趋花习性，能随着寄主植物开花顺序依次转移，棉盲蝽的成虫期决定着其虫量的再分配。绿盲蝽2、3、4代和中黑盲蝽的2、3代为棉田的主害世代，其余世代则主要分布在棉田外寄主上。依照当地不同生态区的环境特点，研究了两种棉盲蝽在各生态区的寄主范围、生态分布与危害特征。并且根据两种棉盲蝽对寄主植物取食危害的差异，划分了棉盲蝽对多种寄主的适合性程度。The results showed that Lygus lucorum had 100 host plants which belonged to 28 families, Adelphocoris suturalis had 105 host plants which belonged to 29 families in farming area of Yancheng through general investigation method during 2004 to 2006. The insects had three times high immigration actions and one immigration in the cotton field. The cotton plant bugs population moved along with the host plant＇ s abloom process, because the insects tended toward tender, green and flower. The primary insects in cotton field were the 2nd, 3rd and 4th generation of Lygus lucorum and the 2nd and 3rd generation of Adelphocoris suturalis. The insects＇ host area, ecological distribution and injury characters had been studied according to the environment. The fitness to different hosts of cotton plant hugs had been divided according to the injury difference of two cotton plant hugs to the host.
