烟台葡萄绿盲蝽的季节性发生规律

摘要

The overwintering sites and seasonal occurrence of Apolygus lucorum (Meyer-Dür) on grapes were investigated in Yantai during 2011-2012.The results showed that most eggs of A.lucorum overwintered in the bud scales of grape,and only a few laid in deadwood and fallen leaves.A.lucorum had five generations per year in Yantai,and the first two generations caused serious damage to grapes.The nymph-hatching dynamics of the first generation peaked in late April.The adults of the second generation largely emerged in mid-and late June,and then moved to other host plants outside vineyards.The third and fourth generations of A.lucorum caused limited damage to grapes.The adults of the fifth generation moved back to vineyards and laid eggs for overwintering in late September.%于2011-2012年系统研究了烟台地区绿盲蝽在葡萄上的越冬场所及其季节性发生规律.结果表明,绿盲蝽以卵越冬,越冬卵主要产在葡萄芽鳞内,极少量产于葡萄枯枝、落叶内；绿盲蝽一年发生5代,世代重叠严重,1、2代为主要危害代；越冬卵于4月下旬达孵化高峰,第2代绿盲蝽成虫于6月中下旬达到羽化高峰,并开始向外转移扩散；第3、4代危害较轻；第5代成虫于9月下旬开始陆续迁回葡萄上产卵越冬.
