绿盲蝽(Lypus lucorum Mey-Dur)一直是长江流域棉区的主要害虫,2003年在冀南棉区暴发成灾。据调查,冀南棉区邯郸、邱县、鸡泽等市县大部分棉田绿盲蝽暴发危害高峰期在7月下旬;成安、广平、临漳等县棉田发生危害高峰期则在8月上旬,百株虫量最高达30-40头。大量棉株顶芽和边心被害,变黑枯死,形成无头苗或激发不定芽萌生,形成枝条疯长。花蕾和幼铃受害常干枯脱落,有时造成黑心僵瓣。近年绿盲蝽暴发已成为该地区棉花减产的主要原因之一。

According to the survey, most cotton fields in Handan, Qiu, Jize and other cities and counties of Hebei Province in southern cotton outbreaks in the peak season in late July; Cheng’an, Guangping, Linzhang cotton fields in the peak damage occurred in August In the early days, the number of hundred insect pests reached as high as 30-40 heads. A large number of cotton plants top buds and border victims, black dead, the formation of non-head seedlings or stimulate adventitious bud initiation, the formation of branches soaring. Buds and young bell victims often shed off, sometimes causing black heart stiff petals. In recent years, the outbreak of green bugs has become one of the main reasons for the reduction of cotton production in the area.
