The dispersal pattern of Anoplophora glabripennis (Motsch.)adults was studied in Qintongxia,Ningxia autonomous region by mark recapture method.After the dispersal parameters have been worked out,the dispersal models were built.The results indicated that the adults population presented normal distribution from the estimation of deviation;the dispersal rate decreased with releasing time.The dispersal density reduced along with the increment of distance and duration;the population average dispersal distanc...
