云南茶叶茸毒蛾的生物学特性与综合防治

 对云南茶叶上发生危害的茸毒蛾主要种类的生物学特性及综合防治研究进行了报道.云南茶园内常见的6个茸毒蛾种类,以茶茸毒蛾、皱茸毒蛾和蔚茸毒蛾危害为主.茶茸毒蛾在茶园中1年发生4～5个世代;生长时期完成1个世代需要61.2～71.5d;越冬代长达146.8d.茸毒蛾的综合防治,充分利用茶叶——害虫——天敌相互作用的生态调控作用,发展生物制剂、农业防治、生态防治等结合的综合治理方法,尽力减少化学农药使用量或者不用化学农药,建立可持继发展的害虫综合防治体系.

The Biological Studies and the Integrated Control of Tea Tussock Moths in Yunnan

This paper was studied the bilolgy and the integrative control of tea tussock moths(Lepidoptera:Dasychira)in Yunnan province.There were in total 6 species of tea tussock moths in Yunnan tea plantations,while chief harm the leaves are Dasychira baibarana and D. caperata and D. glaucinoptera. These tea tussock moths took to complete 4～5 generations and every generation cycle needed 61.2～71.5 days.The integrative control of tea tussock moths that considerd the interaction of tea leaves-pest-natural enemies and the controlled effects of these natural regulative factors for therefore,should develop the rational biological control and agricultural control and ecological control to reduce the usage of insecticides,The integrative control will play an important role especially in tea plantation.
