摘　　要：刺槐尺蠖(Napecheima robiniae Chu)是我国的特有种,除陕西外,还分布于山西、山东、河南、河北等省。60年代初开始在陕西省眉县、耀县等地连年爆发成灾,到80年代,年成灾面积竟达10万亩以上(据1983年普查资料),并在继续扩大。为了探讨经济有效的防治措施1984—1986年我们在永寿县槐平林场和渭南市桥南镇进行了防治试验,现将结果报道如下。Napocheima robiniae is a serious pest of the black locust in Shanxi, Shanxi, Shandong, Henan, Hebei Provinces of China. The area of serious damage was only about 10000 mu in Shanxi early in the sixties, but it is more than 100000 mu in the eigties. It was controlled with poison pencil that poisoned female moths over 80%. The number of larvae decreased 98% when bound band of plastic film on the trunk, and wiped out the eggs on it. The mortality of the first instar larvae reached 98.4-99.9% when sprayed dimilin to the eggs cluster, spraying the water suspension of Bacillus thuringiensis and Beauveria bassiana to the 3—4 instar and fullgrown larvae a 60.0—81.3% and 49.0—55.6% mortality was obtained respectively. The increment of timber reached 0.178—0.225m^3 per mu for the control.
