由于棉铃虫是一种杂食性害虫,除为害棉花外,也为害青椒、西红柿、大葱等多种蔬菜。多年来蔬菜害虫防治多采用化学农药防治,常造成污染,危害人们身体健康,同时易造成抗药性.导致防效降低。为寻找更科学的方法,既杀虫又防止污染,生产出无公害产品。昆虫学家应用高科技原理从棉铃虫雌蛾腹部提取了雌性性诱剂物质,通过加工制成棉铃虫雌性诱芯,供生产上防治棉铃虫使用。现将其防治效果、作用机理及作用方法简介如下。
As the cotton bollworm is a omnivorous pest, in addition to harm cotton, but also harmful green peppers, tomatoes, green onions and other vegetables. Over the years vegetable pest control and more use of chemical pesticide control, often resulting in pollution, endanger people’s health, but also easy to cause resistance, leading to reduced control efficiency. To find a more scientific way, both insecticidal and prevent pollution, to produce pollution-free products. Entomologists using high-tech principles extracted from the female H. armigera abdominal female lure material, processed into a female Helicoverpa armigera induced for the production of control bollworm use. Now its control effect, mechanism and role of the method described below.
