栗山天牛Mallambyx raddei Blessig是紫金山栎林的主要蛀干害虫,林木受害后生长衰弱,形成枯枝、导致风拆,严重影响林地卫生状况和风景区的景观。1989—1990年我们根据该虫成虫趋光性强的习性,采用黑光灯进行林间虫情监测和诱杀成虫试验,取得了较好的效果。现总结于下。 Malus bambusae, Mallambyx raddei Blessig is the main stem borer in the Quercus aliena var.mongolica forest. After the trees have been damaged, the trees grow weak and become litter, leading to wind-clearing and seriously affecting the health status of the forestland and the landscape of the scenic area. From 1989 to 1990, based on the habit of phototacticity of adult worms, we tested the insect monitoring and trapping adults with black light, and achieved good results. Now summarized in the next.
