COMPUTER SIMULATION OF POPULATION DYNAMICS OF THE ORIENTAL ARMY WORM (MYTH1MNA SEPARATA)
粘虫种群动态模拟的研究

This paper describles a new way of calculating the population dynamic of the oriental armyworm both in time and in number. Based on the difference equation of Ruesink (1976) with a slight modification, we use equation (2) in the text to simulate armyworm population dynamic under the daily varying natural temperature.Considering the fact the intervals between the appearance of max. temperature (at about 14:00) and that of min. temperature (at about 5:00) are not equal an asymmetrical sine function is propose...
