摘要
玉米每年因病虫危害损失产量约占总产量的１／３左右。中国对玉米病虫害的防治研究始于本世纪初期；５０年代以后取得较大的进展，确立了“预防为主，综合防治”的植物保护方针，玉米螟生物防治研究居世界领先水平；８０年代以来全国玉米病虫害防治协作攻关研究取得显著成绩。
The reduction of corn output is about one third of the total amount because of diseases and pests. In China, the study on the prevention and control of corn diseases and the elimination of pests started in the early part of the 20th century, and has made great progress since the 1950s. The principle of plant protection was determined, which consists of 'giving first place to prevention, and adopting comprehensive prevention and control.' China's biological prevention and control of the corn borer took the lead in the world. The cooperative study of China on the prevention and control of corn diseases and the elimination of pests since the 1980s has achieved remarkable success.
