在害虫的综合治理中,诱杀法不仅具有良好的杀虫效果,而且省药、省力、省时,可以大大减少农药的施用量,降低农药对环境的污染。针对不同害虫,常用的诱杀方法有:1.黑光灯诱杀法利用害虫的趋光性,每2~3公顷地设置一盏黑光灯,每晚9点至次日凌晨4点开灯,可诱杀小菜蛾、斜纹夜蛾、甜菜夜蛾、小地老虎、烟青虫、豆荚螟、蝼蛄、金龟子、棉铃虫、蟋蟀等数百种害虫,尤其在天气闷热、无月光、无风的夜晚,诱杀效果更好。需要说明的是,灯光诱虫必须大面积进行才能收到良好效果,否则反而会造成局部地块受害加重。
In the comprehensive management of pests, the trapping and killing method not only has a good insecticidal effect, but also saves medicine, saves labor and saves time, can greatly reduce the application amount of pesticides and reduce the pollution of pesticides to the environment. For different pests, commonly used trapping methods are: 1. Black light trap method to use pest phototaxis, every 2 ~ 3 hectares to set a black light, every night 9:00 to 4:00 the next day to turn on the light, the trap Plutella xylostella , Spodoptera litura, Beet armyworm, Land tiger, tobacco budworm, pod borer, slug, beetle, cotton bollworm, crickets and other hundreds of pests, especially in the hot weather, moonless, windy night, the trapping effect is better . It should be noted that the light trap must be a large area to get good results, but otherwise it will result in increased partial land damage.
