粘虫是一种世界性虫害,主要为害麦、粟、玉米、高粱、水稻、旱稻、青稞等禾谷类作物。然而其迁飞为害规律仍旧是个“谜”。我国农业科学工作者从五十年代初始,经过近30年的研究,现已发现、肯定粘虫南北往返迁飞为害的规律。 Army worm is a worldwide pest, mainly wheat, millet, corn, sorghum, rice, Upland rice, barley and other cereal crops. However, the law of its migration is still a “mystery.” After nearly 30 years of research, from the beginning of the 1950s, agricultural scientists in our country have discovered and confirmed the law that migratory insects migrate from north to south for a long time.
