棉蚜是朝阳棉区的重要害虫,由于单纯依靠化学杀虫剂防治,结果虫害越来越重。朝阳县十二台公社自1975～1981年以来,采取了利用和保护当地天敌,积极开展综合防治棉蚜,几年来收到了明显的效果。1980年全公社9249亩棉田中7817亩棉田完全未用杀虫剂,1107亩棉田基本没有使用化学杀虫剂,仅点片阶段点涂1～2次,就是在棉蚜特大发生的1981年,全社12240亩棉田中5225亩棉田完全未用杀虫剂,5220亩棉田也仅仅点涂1～2次,这两年都有效地控制了棉蚜的危害。几年来防治费用大大降低,仅十二台公社3年就节省用药资金十万多元。皮棉单产接近或略高于同类地块的纯化防棉田。实践证明这种方法是可行的。
Cotton aphid is an important pest in Chaoyang cotton area. As a result of purely chemical insecticide control, insect pests are heavier and heavier. Twelve communes in Chaoyang County have taken effective measures to prevent and control cotton aphids by utilizing and protecting native predators since 1975 ~ 1981, and have achieved remarkable results in recent years. In 1980 9249 acres of cotton fields in the communes community 7,817 acres of cotton fields completely without pesticides, 1107 acres of cotton fields basically no use of chemical pesticides, spot-point stage coating 1 or 2 times, is a cotton aphid occurred in 1981, The whole community 12240 acres of cotton fields in 5225 acres of cotton fields completely insecticide, 5220 acres of cotton fields are only coated 1 or 2 times, the past two years are effectively control the harm of cotton aphids. In recent years, the cost of prevention and treatment has been greatly reduced. Only three communes of twelve communes have saved over one hundred thousand yuan of medication funds. Lint yield close to or slightly higher than the same type of pure anti-cotton fields. Practice has proved that this method is feasible.
