草蛉是多种农林害虫的天敌。根据草蛉成虫有较强的趋光性的特点,我们试制了一种手提式简易灯光诱蛉箱。据试验,晚上每只箱每小时可诱集草蛉300多头,比用圆筒扑虫网提高工效5倍,同时没有机械损伤,成活率可达99％,是人工助迁草蛉,防治棉田害虫较理想的一种工具。诱蛉箱的结构分为: 1.诱蛉口:诱蛉口是草蛉趋光后汇集成群的地方。口长6、0尺、宽3.0尺、高4.5尺,口前有遮蛉布,防止草蛉诱满后飞出,后口钉有窗纱,隔离趋光而来的草蛉,以免草蛉趋集灯光周围,减弱光线,影响诱蛉数量。 2.电源箱:电源箱是用来安装电源发
Grass is a variety of natural enemies of agricultural and forestry pests. Based on the strong phototaxis characteristics of adult weeds, we experimented with a hand-held simple light trap box. According to the test, at night, each box can trap more than 300 heads of grass per hour at night, which is 5 times more ergonomic than that of cylindrical insects net. At the same time, there is no mechanical damage and the survival rate can reach 99% A pest more ideal tool. The structure of the bait box is divided into: 1. Induced 蛉 mouth: induced 蛉 mouth is the convergence of grass 蛉 light after a group of places. Length of 6,0 feet, 3.0 feet wide, 4.5 feet high, the front of the cover cloth, to prevent the cattail after the full flight out, after the mouth nailed gauze, isolated from the light of the lawn, to avoid the lawn Set the light around, weaken the light, affecting the number of inducement. 2. Power Box: Power box is used to install the power hair
