摘　　要：在云南省薄壳山核桃和八角主要种植区进行这2种干果经济林主要害虫的天敌类群调查,共获得主要害虫寄生性天敌25种,捕食性天敌45种,对天敌类群的分布规律进行了分析.研究结果表明,云南省薄壳山核桃和八角林内主要害虫的天敌资源比较丰富,天敌的类群及数量与林木受病虫的危害程度有一定的相关性,即在危害严重的种植园中,天敌的数量也相对较多.利用天敌资源控制主要害虫应是可行的.Natural enemies of main pest insects of Carya illinoensis and Illicium verum were investigated at the main plantation regions of the two economic tree species in Yunnan. Twenty-five parasitoids and forty-five predatory natural enemies of the main pest insects of the two tree species were collected. Distri- bution features of these natural enemies were analyzed in the paper. The results provided basis data for utilizing natural enemies to control pest insects of the two economic tree species.
