Abstract:In order to explore the dispersal pattern and the dynamics of Anoplophora glabripennis population in the nature, the authors studied the dispersal regulations of A. glabripennis by using the mark-recapture method in Yongjing County, Gansu Province. On the basis of collecting the dispersal data by the time-series process of A. glabripennis adult population, the dispersal pattern of A. glabripennis adults in poplar shelter forest network was studied and the factors effecting the dispersal were analyzed. The results indicated that the population dispersal had obvious direction was caused mainly by the environment. Meteorological factor analysis showed that the dispersal pattern was affected mainly by the wind direction. The amount of recapture at all direction had negative relationship with the same wind direction and positive relationship with the opposite wind direction, while it had no close relationship with wind speed, temperature and relative humidity. The dispersal density of adults decreased with the increase of distance and time, the relationship between the dispersal distance and the amount of adults could be described by the mathematic model y=4 203.568 3x-1.117 56. The population average dispersal distance was 423.7 m. There was no difference of dispersal direction and distance between male and female adults, only the recapture rate of male was higher than female. Adults could disperse to more than 2 000 m and even more. The farthest dispersal distance observed was 2 644 m.
