摘要
对绿盲蝽在果树上的发生、危害及综合防治策略进行了调查研究。结果表明:在德州市该虫1年发生5代,主要以卵在枣树多年生枣股芽鳞内和地面双子叶杂草上越冬。1~2代危害果树,2代成虫转主于棉花,第5代成虫于10月初开始返回果树产卵越冬。防治上应抓住关键时期,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。
Occurrence,damage and synthetic control of Lygus lucorum in the fruit tree were observed.The results showed that the pest had five generations per year in Dezhou city,overwintered in the bulbils of perennial fruit branches of jujube and dichotyledonous grass by eggs.The first and the second generations of the pest were on fruit tree and then the adult of the second gerenation shifted from fruit tree to cotton.The adult of the fifth generation returnted to fruit tree to lay eggs for overwintering in early october.So we should hatch critical time to kill the pest before eclosion and movement.
