杨扇舟蛾的生物学特性及其防治方法

杨树是世界上最有价值的树种之一,近年来杨扇舟蛾Clostera anachoreta(Fabricius)对之造成的危害日益突出,但是目前有关该害虫的综合报道尚十分少见。文献报道显示,该害虫在我国大部分省区都有不同程度地发生,每年大多发生4~5代,5~8月份的2龄和3龄幼虫危害最重,老熟幼虫结茧越冬;其天敌大约有30种以上。目前害虫的防治方法较多,主要包括人工消灭方法、诱杀方法、树干内外施药方法、微生物方法、寄生蜂方法、生物导弹方法以及农业智能专家系统辅助方法。其中微生物方法、生物导弹方法以及农业智能专家系统辅助方法具有十分广阔的应用前景。

Biology of Clostera anachoreta and its control methods

Poplar is one of the most valuable cosmopolitan trees. Recently, Clostera anachoreta(Fabricius) has caused serious damage in China forest industry, while there is a lack of the integrated reports about this pest. Based on the recent reports, C. anachoreta has occurred different degree among many provinces of China. It occurs 4～5 generations every year, the 2～3 instar larvae can cause the serious damage from May to August, and it depends on mature-larva to overwinter. C. anachoreta has about 30 strain natural enemies. There are various control methods to the pest, including manpower, entrapment, chemical pesticide, microorganism pesticide, Trichogramma, biological guided missile and agriculture expert system. Among these methods microorganism pesticide, biological guided missile and agriculture expert system have expensively applied foreground.
