We studied dispersal and spatiotemporal dynamics of the Asian Longhorned beetle, Anoplophora glabripennis Motschulsky, in Gansu Province of north central China. We used mass mark-recapture methods and observed that at distances > 295 m from a release point, the recapture rate was < 5%, while the median dispersal rate for all recaptured adults was 30 m/d. Dispersal potential within the course of a season for males and gravid females was 2,394 and 2,644 m, respectively; however, more work is need to evaluate the potential of long distance dispersal events to initiate new colonies outside current U.S. quarantine boundary guidelines. Peak population abundance of unmarked beetles (i.e., background populations) in both 1999 and 2000 occurred between 800-900 degree days (base threshold=10 ºC) from 1 January. Background populations exhibited local spatial autocorrelation during peak abundance, with ranges of spatial dependence of 229-543 m.
