摘要
对苹果绵蚜Eriosoma lanigerum(Hausmann)在伊犁河谷的越冬生物学及迁移规律进行了分析,结果表明,在伊犁河谷苹果绵蚜无翅孤雌蚜越冬主要位于根蘖部,其次在树干和枝条上。全年只有一次迁移高峰期并靠若蚜来进行。无翅孤雌蚜在1d的迁移高峰在16:00至17:00,阴天活动量少。在温度25-28℃的条件下完成一代所需要的时间平均为12.04d。
The paper has researched overwinter biology and remove rule of the woolly apple aphid Eriosoma lanigerum (Hausmann)in Ili River Valley. E. lanigerum mainly lives at the root, tree trunk and branches for overwinter. There is only one remove peak in one year by the nymphae. The move peak of E. lanigerum is from 16.00--17.00 p.m. in one day, the number of nymphae which move on cloudy day are less than that on sunny day. Under the temperature of 25--28 ℃ ,it takes average 12.04 d for finish one generation.
