粘虫迁飞模拟试验

粘虫是我国禾谷类作物的主要迁飞性害虫之一。近十多年来,我国昆虫学者在迁飞问题上作了大量研究工作。迄今已基本摸清了我国东部粘虫的远距离迁飞、迁飞方向及路线(林昌善等,1963;林昌善、张宗炳,1963),分析了粘虫迁飞的生理生态机制(马世骏,1963)和迁飞与气流场的关系(林昌善,19632 赵圣菊等,1981),开展了一些粘虫飞行的观察和

EXPERIMENTS ON THE FLIGHT ACTIVITY OF THE ORIENTAL ARMYWORM MOTHS, MYTHIMNA SEPARATA (WALKER)

This paper gives a brief account of the results of our experiments on the effects of the age, physiological condition (e. g. hunger), and wind speed on the flight activity of the Oriental armyworm moths. Our experiments show that the flying ability of armyworm moths varies with their maturity after the emergence of the pupa. The flight capacity of moths is at the highest peak during 3-5 days of age. The duration of their continuous flying varies from 0.27 to 11.23 hours per day during 1-8 days of age. The a...
