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。
We systematically studied the occurrence and transmigration characteristics of Apolygus lucorum on the main hosts in Cangzhou, Hebei Province. The results showed that jujube and cotton were the main hosts for each other in Cangzhou, Hebei Province. The first to the second generation were the main types of jujube trees. The second generation adults were mainly cotton and other crops. The main peak was June 19 ~ On the 25th, 3 to 4 generations of cotton and other crops damage, the 5th generation of adults began returning early jujube in early September spawning winter. Lygus litchi 1 or 2 generations of nymphs hatching time concentrated adult emergence peak obvious. According to the weak link in the life history of Lygus, we put forward the strategy of prevention and cure before grasping the critical period, taking a large area of unified prevention and control, and eliminating the insects before they hatch and become adults.
