棉蚜（ＡｐｈｉｓｇｏｓｓｙｐｐｉＧｌｏｖｅｒ）在棉花苗期普遍发生且危害严重。由于棉产区多年来频繁使用化学农药防治棉蚜，使棉蚜抗药性增强，同时大量杀伤天敌，造成环境污染，致使棉蚜更加猖獗在为害，对棉花产量影响很大．本试验是观察不同类型棉田棉蚜及其主要天敌的消长，以及天敌对棉蚜的控制效果，观察表明：棉田自然天敌对苗期棉蚜一般是可。控制其为害的；在生产活动中，要协调各项措施，尽量减少对天敌的影响，以提高其对棉蚜的自然控制能力。
Cotton aphid (Aphis gossyppiGlover) in the cotton seedling stage and serious harm. Due to the frequent use of chemical pesticides to control cotton aphids in cotton producing areas over many years, the resistance of cotton aphids is enhanced, and a large number of natural enemies are killed at the same time, resulting in environmental pollution, causing cotton aphids to be more rampant and harmful to cotton yield. This experiment is to observe the growth and decline of cotton aphid and its major natural enemies in different cotton fields, and the control effect of natural enemies on cotton aphid. The results showed that cotton aphid natural enemies are generally suitable for cotton aphid at seedling stage. Control their harm; in the production activities, to coordinate the various measures to minimize the impact on natural enemies in order to improve its natural control of cotton aphids.
