EXPERIMENTS ON THE FLIGHT ACTIVITY OF THE ORIENTAL ARMYWORM MOTHS, MYTHIMNA SEPARATA (WALKER)
粘虫迁飞模拟试验

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...
