超低容量喷雾杀虫是六十年代初发展起来的一门新技术,目前在非洲、美国、日本及西欧等地区已普遍采用。我国从七十年代开始使用这一技术,并取得一定效果。但到目前为止,国内外均未见过应用白僵菌进行超低容量治虫的报道。为了克服农药对环境的污染,害虫的抗药性和在防治过程中杀伤天敌等缺点,解决应用白僵菌粉剂治虫存在的菌粉运输量大、保存时间短、粘着力差,耗菌多等问题,我们从1979年起开展白僵菌超低容量防治松毛虫的研究工作,试图通过研究,把白僵菌防治森林害虫的技术水平提高一步。
Ultra-low volume spray insecticide is a new technology developed in the early 1960s and is currently widely used in Africa, the United States, Japan and Western Europe. Our country started to use this technology from seventies, and achieved some results. But so far, no application of Beauveria bassiana to ultra-low-volume pest control has been reported at home and abroad. In order to overcome the pollution of pesticides to the environment, the resistance of pests and the natural enemies in the process of prevention and treatment and other shortcomings, to solve the application of Beauveria bassiana powder pest management of large transport capacity, storage time is short, poor adhesion, consumption and more problems , We carried out the research on the ultra-low capacity Beauveria bassiana against pine caterpillars since 1979, trying to improve the technical level of Beauveria bassiana against forest pests through research.
