豆天蛾Clanis bilineata是我国黄淮大豆产区主要害虫之一。近年来在淮北等地连年大量发生和为害,在生产上造成严重损失。以往防治主要依靠666等化学杀虫剂,对天敌等有益生物群落和环境造成不良后果。自从666停产禁用后,迫切要求提供比较理想的杀虫剂。经两年来室内外试验和1万5千亩大面积防治示范,证明青虫菌6号液剂对豆天蛾幼虫有非常好的防治效果,并对豆田几种主要捕食天敌基本上能起良好保护作用。
Bean moth Clanis bilineata is one of the major pests in Huanghuai Soybean Production Area in China. In recent years, large numbers of pests and injuries have taken place in various places in Huaibei and other places, causing serious losses in production. In the past, prevention and treatment mainly relied on chemical insecticides such as 666 to cause adverse effects on natural enemies and other beneficial biological communities and the environment. Since 666 was discontinued, there has been an urgent need to provide better pesticides. After two years of indoor and outdoor experiments and a large area of 15,000 mu of prevention and control demonstration, prove that No. 6 liquid worm on the bean moth larvae have very good control effect, and several main predators in soybean fields can basically play a good protection effect.
