摘    要:本对绿盲蝽在Bt转基因棉及枣树上的发生规律进行了系统研究,结果表明,在沧州地区绿盲蝽以卵在枣树多年生枣股芽鳞内和地面双子叶杂草上越冬,在多年生枣股芽鳞内的越冬卵占总卵数的91.5%,在地面双子叶杂草上的越冬卵仅占总卵数的8.5%。该虫1年发生5代,枣树和棉花是该虫的主要互为寄主,1—2代危害枣树,2代成虫转主于棉花,转主高峰为6月19—25日,3—5代危害棉花,第5代成虫于9月初开始返回枣树产卵越冬。1—3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。

Abstract:In this study, occurrence trend of Lygus lucorum Meyer-Dur. in the Bt cotton and jujube field were observed.The studies indicated that L.lucorum overwintered in the bulbils of perennial fruit branches of jujube and dichotyledonous grass where 91.5% and 8.5% of the total eggs were observed,respectively.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 during the third week of June.The third to fifth generations damaged cotton and the adults of the fifth generation returned to jujube to lay eggs for overwintering.For first to the third generations,hatching time was in a well defined and short temporal window and also adult eclosion had evident peaks,so this critical time can be targeted to kill the pest before eclosion and movement to cotton.
Keywords:Lygus lucorum  overwintering  occurrence trends  jujube  cotton
