| 摘 要： | 利用昆虫飞行数据微机采集系统对粘虫Mytkimna separata(W&lker)蛾飞行能力的测定结果表明：产卵前，雌蛾的飞行能力随蛾龄的增长而增加；产卵后，以产卵l天后的飞行能力最强，之后随产卵历期延长和产卵量的增加而下降。产卵超过6天或1 200粒的成虫飞行能力已基本丧失。由此认为：粘虫蛾的迁飞是在产卵前进行；成虫的飞行能力与卵巢发育同步，因而在粘虫中可能不存在卵子发生飞行拮抗症。最后对粘虫产卵后仍具有一定飞行能力的生物学意义进行了探讨。

| Abstract: | The flight capacity of female adult in relation to oviposition in Oriental armyworm,Mythimna separata (Walker), one of the most detrimental migratory insect pests in China, was determined by the tethered-flight technique under laboratory condition. The females were more capable of flight as their age increased in days and reached a peak on the days immediately after ovipositon began, with an average of 10.1 hours in duration and 58.6 kilometers in distance during the 12-hour test. indicating that there is perhaps no oogenesis-flight syndrome in this species. The flight capacity of the female, however was significantly declined 2 days after oviposition (DAO) and almost ceased on 6 DAO. The flight capacity of female was also highly related to the number of egg they laid. About 55% of the moths flow over 36 kilometers when they laid less than 300 eggs while none of them could fly such distance when they laid more than 1200 eggs. It is therefore deduced that the incidence of migration is just at the post-teneral stage of the adult in M. teperato since the female's flight capacity was sharply declined as the ovipositional period extended and egg number increased. The flight capacity remained in the ovipositing female is of great significances in food and oyipositional site finding for its weekly ovipositional period both in the laboratory and in the field. |
