白蜡窄吉丁在我国危害的变化及防治

The Changes and Management of Infestation of Agrilus planipennis in China

白蜡窄吉丁是中国本土害虫,一直以来对我国本土的白蜡树危害不严重,是一种次要害虫。但近年来,随着外来引种白蜡树的广泛栽植,白蜡窄吉丁由次要害虫演变成为主要害虫,对我国园林绿化、植树造林中大量种植的白蜡树造成了巨大破坏,影响了种植地区的生态环境。本文分析了白蜡窄吉丁由次要害虫演化为主要害虫的原因,总结了该虫的防治现状,尤其是近年来利用天敌防控白蜡窄吉丁的情况,指出天敌是控制其种群数量、减少危害的重要因子,明确以生物防治为主结合多种措施是控制白蜡窄吉丁扩散、减轻生态和经济损失的有效方法,可为其他钻蛀性害虫的防控提供参考。

Agrilus planipennis is a native insect pest in China,and has not caused serious damage to local Fraxinus trees previously.However,in recent years,with the widespread planting of exotic Fraxinus trees,A.planipennis has evolved from a secondary pest to a major pest in China,causing great damage to Fraxinus trees in landscaping and afforestation,and posing a serious threat to the environment.In this article,the outbreak reasons of A.planipennis and the current situation of its control,especially the use of natural enemies in recent years were summarized.It was found that the use of natural enemies is one of the fundamental factors in controlling the insect population and damage.The use of biological control combined with multiple measures is an effective method to control the spread of A.planipennis and reduce ecological and economic losses.The article can provide a experience for the prevention and control of other trunk-boring pests.
