河南冬枣和葡萄上绿盲蝽种群的季节性发生规律

Seasonal population dynamics of Apolygus lucorum on winter jujube and grape trees in Henan Province

4月初到7月底,调查了绿盲蝽在冬枣和葡萄树上的越冬部位,监测了其在葡萄树上的种群动态及寄主转移规律。结果表明绿盲蝽越冬卵在葡萄树和冬枣树的剪口、葡萄的冬芽以及冬枣树的翘皮等部位越冬,并发现绿盲蝽越冬卵的孵化不整齐还可能和葡萄冬芽发育的不整齐有关。调查结果还揭示了越冬后绿盲蝽在葡萄树上发生的种群动态及其在寄主植物之间的转移规律。本文讨论了这些发现与控制绿盲蝽为害的关系,提出4月初越冬卵孵化高峰期施药以及种植诱集植物(如胡萝卜)诱杀绿盲蝽成虫从而实现绿盲蝽区域性控制的策略。

Overwintering site and population dynamics of Apolygus lucorum on winter jujube and grape trees and host transfer of this species were investigated during early April to late July.Overwintering eggs of A.lucorum were laid in pruned wounds on grape and winter jujube trees,as well as on winter buds of grape and beneath barks of winter jujube tree.The investigation also suggested that the dispersed hatching dates of overwintering eggs might be a result of synchronized development with winter buds of grape.The population dynamics of A.lucorum on grape and host transfer rule were revealed.The links between these findings and the control tactics for A.lucorum were discussed.It was suggested to spray pesticide once the overwintering eggs hatch massively in early April and trap adults of A.lucorum with cultured blooming carrots as a regional control strategy.
