摘　　要：系统研究了绿盲蝽在河北省沧州棉区主要寄主上的发生规律及转主迁移特点。结果表明,在河北省沧州棉区,枣树和棉花是该虫的主要互为寄主,1~2代主要为害枣树,2代成虫转主于棉花等作物,转主高峰为6月19~25日,3~4代为害棉花和其他作物,第5代成虫于9月初开始返回枣树产卵越冬。绿盲蝽1~2代若虫孵化时间集中,成虫羽化高峰明显。根据绿盲蝽生活史中的薄弱环节,提出了抓住关键时期,采取大面积统一防治,将该虫消灭在孵化期和成虫羽化及转主之前的防治策略。Occurrence of Apolygus lucorum Meye^Diir on major hosts in the cotton region of Cangzhou was investi- gated in this study. The results showed that the pest had five generations per year with cotton and jujube as the major hosts. The first two generations of the pest were on jujube and then the adults of the second generation shifted from jujube to cotton and other crops during the third week of June. The third to fourth generations damaged cotton and the adults of the fifth generation returned to jujube to lay eggs for overwintering. For the first and second gener- ations, the hatching time was well defined and adult eclosion had evident peaks. So these critical periods could be tar- geted to control the pest before the adults emerge and move to the cotton and other crops.
