刚竹毒蛾生物学特性及防治研究

刚竹毒蛾Pantana phyllostachysae Chao 1年发生3代,以卵和初孵幼虫越冬,越冬幼虫翌年3月开始活动,6月上旬为第1代幼虫孵化盛期,8月下旬为第2代幼虫孵化盛期,11月出现第3代幼虫。气温是影响刚竹毒蛾危害的重要因素,在防治上要抓住幼虫3龄期前和成虫期进行防治,使用2.5%溴氰菊酯、80%敌敌畏和柴油按1:0.5:50制成的油烟剂防治效果最好。

STUDIES ON THE BIOLOGICAL CHARACTERISTICS AND CONTROL OF PANTANA PHYLLOSTACHYSAE CHAO

Pantana phyllostachysae Chao occurs there generations annually.The egg and larva are the over-wintering stages.The over-wintering larvae begin to be active in March.Most of the first generation larvae hatch in the first ten days of June;the second generation larvae hatch mostly in the last ten days of August,and the third generation larvae emerge in November.Air temperature is the important factor to affect the harm by Pantana phyllostachysae Chao to bamboo.The suitable control phases are the 3rd instar lar...
