本文用吊飞装置测定了棉铃虫成虫不同日龄的飞行能力，测得３日龄雌蛾平均飞行速度为０．９２ｍ／ｓ，平均飞行时间为９．７２±３．６２ｈ，并与其他迁飞性和非迁飞性昆虫作了比较。在实验室条件下研究了温度和食料对生殖前期及繁殖的影响，证实此虫适于迁飞的生理时期较短，最多仅１～２个夜晚。用雌蛾卵巢解剖方法比较了江苏丰县和辽宁朝阳两地二代和三代的虫源性质，分析了两地的发蛾特征。证实朝阳１９９５～１９９６年的二代和部分三代成虫均从外地迁入，但与粘虫不同，迁入种群无突增现象，蛾群稀疏而持续不断。而江苏丰县则在１９９４～１９９６年均无明显迁入现象，以本地虫源为主。讨论了中国棉铃虫的迁飞势能和兼性迁飞的特性。
In this paper, the flying ability of adult cotton bollworm at different days of age was measured with a flying device. The average flying speed of 3-day-old female moths was 0.92 m / s and the average flight time was 9.72 ± 3.62 h, Flies and non-migratory insects were compared. The effects of temperature and foodstuff on pre-breeding and reproduction were studied under laboratory conditions. The physiological period of migration of this pest was confirmed to be short, with a maximum of only 1-2 nights. The anatomy of female moth ovary was used to compare the characteristics of the second and third generations of insect pests in Fengxian, Jiangsu Province and Chaoyang, Liaoning Province. It was confirmed that the second generation and some third generation adults of Chaoyang migrated from other places during 1995-1996. However, unlike the armyworm, there was no sudden increase in the population and the population was sparse and continuous. However, Fengxian County, Jiangsu Province, did not see any obvious migration from 1994 to 1996, mainly local insect pests. The migratory potential and facultative migration characteristics of Chinese cotton bollworm were discussed.
