黄河三角洲地区云斑白条天牛的发生危害与防治

Occurrence,Injury and Control of Batocera lineolata in Yellow River Delta

云斑白条天牛是我国重要林木蛀干害虫,分布广泛,寄主众多,防治非常困难。通过实地调查,发现在黄河三角洲地区云斑白条天牛主要危害白蜡树。详细记述了黄河三角洲地区危害白蜡云斑白条天牛的形态特征、发生规律和生物学习性、危害特征,根据其在黄河三角洲地区的生物学习性和危害特征,提出适宜的防治措施和策略,建议开展以释放天敌昆虫花绒寄甲为主的综合防治技术措施,最终实现云斑白条天牛在黄河三角洲地区的可持续控制。

Batocera lineolatais a stem-borer with so wide distribution and lots of hosts that it is difficult to control.The foundations are given by investigation.B.lineolata mainly attacks ash trees in Yellow River Delta.It is described that morphological features,occurrence regulation and biological habits,and injury characters of B.lineolata have been attacking ash trees in Yellow River Delta.According to the biological habits and injury characters,suitable control methods and strategy are provided.Sustainable control of B.lineolata will be realized by applying biological method and other technologies,and the biological method is to release Dastarcus helophoroides,an natrual enemy of B.lineolata,in damaged forest.
