棉蚜(Aphis gossypii Glover)是新疆近年严重发生的一种害虫,以吐鲁番、喀什、阿克苏等地发生最重.特别是6—8月,棉株上“伏蚜”虫口密集,蜜露粘稠,严重影响光合作用,从而影响现蕾、开花和棉铃的生长.受害轻者叶片卷曲,生长受阻,重者植株调萎.为了给预报和防治工作提供依据,我们于1987年在乌鲁木齐老满城对棉蚜生活历期、繁殖与温度的关系进行了观察研究,现简报于下. Aphis gossypii Glover is one of the most serious pests in Xinjiang in recent years, with Turpan, Kashgar and Aksu occurring the heaviest, especially from June to August, , Seriously affecting the photosynthesis, thus affecting the budding, flowering and boll growth.Slight damage leaves crimp, growth retardation, severe plant wilting.In order to provide a basis for forecasting and prevention work, we in 1987 in Urumqi, Lao Mancheng The relationship between cotton aphid life cycle, reproduction and temperature were observed and studied.
