棉红铃虫是世界性的棉花大害虫。多年来,广大棉区一直使用剧毒农药防治,但效果不够理想,且易产生药害和环境污染。因此,急需寻找一种简便有效的防治手段,特别是从昆虫本身的习性特点的内在因素中去探索防治害虫的新方法和新途径。现介绍一种利用红铃虫雌蛾粗提物(能引诱雄蛾的天然粗制品)来诱杀红铃虫的新方法。经上海川沙县、安徽省巢县等地大田试验证明:棉田设置带有一张含有相当于5-10头红铃虫雌蛾粗提物纸蕊的简易盆式诱杀器,在红铃虫发蛾期间,一个晚上最多可诱杀800多头
Cotton bollworm is a worldwide cotton pest. Over the years, the vast cotton area has been using highly toxic pesticides for prevention and treatment, but the effect is not ideal and prone to injury and environmental pollution. Therefore, it is urgent to find a simple and effective means of prevention and control, especially from the inherent characteristics of the insect itself to explore new ways and new ways to control pests. A new method for trapping Helicoverpa armigera using a crude extract of the female N. moth, a natural crude that can induce male moths, is presented. Experiments in Chuansha County of Shanghai and Chao County of Anhui Province showed that the cotton field was set up with a simple pot trap containing a paper core of the crude extract of female moths of 5 to 10 heads of red bollworm, During the night, a maximum of 800 bells can be killed
