摘　　要：为了降低化学防治桦三节叶蜂对环境造成负面影响,通过开展人工摘茧防治、野外挂袋、采茧室内培育后林间放蜂等方法,探索其寄生性天敌的保护利用。研究表明,秋季收集的桦三节叶蜂茧,进行室内培育,翌年,天敌羽化期,到林间集中释放,可明显提升天敌对桦三节叶蜂的寄生率。另外,在秋季以人工摘茧的方式对桦三节叶蜂的预防,可明显降低桦三节叶蜂虫口基数。In order to avoid bad effects on the environment while control the Arge pullata（Zaddach）,two methods are explored,which involve protecting its parasitic natural enemies as well as picking cocoon.Preliminary study showed that the cocoons are collected and nurtured indoors in the autumn.By releasing natural enemies during their emergence period next year,the parasitism rate of natural enemies can be obviously improved.In addition,picking cocoon in autumn can help to reduce the worm base of Arge pullata（Zaddach）.
