罕山林场一九八二年舞毒蛾发生面积达三万二千亩,为害较为严重的有百分之六十。为了及时有效地扑杀,在害虫猖獗的作业区,用高压电网杀虫灯进行诱杀,效果较为理想。高压电网杀虫灯设置在背风、虫口密度较大、控制面积较广的山坡中部。每个灯的防治半径可达二百五十米,高度超过树冠一至二米,两灯间距离四百至五百米。为了扩大杀虫面积,中间可移动灯位。
In 1982, Gansu Moth occurred in Han Shan Forest Farm with an area of 32,000 mu and the more serious damage was 60%. In order to promptly and effectively culling, in the pest rampant operation area, using high-voltage grid insecticidal lamp trapping, the effect is more satisfactory. High-voltage grid insecticidal lamp set in the leeward, insect population density, control a wide area of the central hillside. Each lamp has a radius of up to 250 meters and a crown height of 1-2 meters. The distance between two lamps ranges from 400 to 500 meters.
