沙柳是固沙造林的主要先锋树种之一,也是群众用作烧柴、编织、盖房、饲料的主要来源,在“三北”防护林建设和人民生产、生活中占有重要地位。近年来,由于遭受沙柳木蠹蛾为害,沙柳死亡十分严重。为探索有效的防治途径,尽快控制该虫继续扩散蔓延,从1981～1984年,我们以定边县长茂滩林场为基点,对该虫进行观察研究,并在横山、榆林、神木等县设点开展防治试验,取得明显效果。现将几年来观察研究结果整理如下:一、害虫名称及分布沙柳木蠹蛾(HoIcocerus sp.)属鳞翅目(Lepidoptere),木蠹蛾科(Cossidae),
Salix psammophila is one of the main pioneer tree species for afforestation and afforestation. It is also the main source of firewood, weaving, building houses and feedstuffs used by the masses. It occupies an important position in the construction of “Three Norths” shelterbelt and people’s production and living. In recent years, the Salix willow death is very serious due to the damage caused by Salix psammophila. In order to explore an effective control approach and control the spread of the pest as soon as possible, from 1981 to 1984, we observed and studied the pest on the basis of Changmaitan Beach in Dingbian County, and set up a pilot study in Yokoyama, Yulin and Shenmu counties To carry out prevention and control tests, achieved significant results. The results of several years of observational research are summarized as follows: I. Pest Names and Distribution HoIcocerus sp. Belongs to Lepidoptere, Cossidae,
