| 摘 要： | 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。

| Abstract: | Repeated chemical control of cotton aphid (Aphis gossypii Glover)often results in subsequent serious infestations of the bollworm of even the cotton aphid itself in Chaoyang,Liaoning Province,China.Twelve species of native spiders (and other aphidophagous insect species) have been observed controlling effectively aphids below crop-damaging levels in an unsprayed cotton field for six consecutive cotton seasons(1975-1981).The area left unsprayed increased from 50 to 7817 mu in these experimental seasons. |
