摘　　要：在应用“竹腔注射”技术防治竹螟基础上,着重对其它防治方法进行了研究。研究结果指出,冬季垦复可降低竹螟土茧密度80％以上;高虫口密度时,采用蜜源地灭蛾可降低虫口150条/株以上,一块50亩左右的蜜源地天蛾可控制1500亩左右竹林幼虫的为害;一盏20瓦高压触杀灯可控制370亩左右竹林竹螟为害,并使幼虫虫口减少至103条左右/株。Bamboo leaf-roller, Algedonia coclesalis (Walker), is one of the most dangerous defolitors in bamboo stands in Zhejiang province. Over 80% of cocoon density of A. coclesalis at ground was reduced by cultivation in winter's season, 150 defoliators on per plant was reduced by killing adult moth at high population density on the nectar source pasture. About 50 mu of nectar source pasture could prevent the larvae of A, coclesalis from injuring range 1500 mu of bamboo forests and about 370 mu of bamboo forests could be protected by a moth-killing lamp with high voltage of 20 watt.
