Flight activity and dispersal of the spruce bark beetle Ips typographus (Col., Scolytinae)

The knowledge of the actual weather conditions and the wind speed at the time of beetle swarming from the release site and their recapture in the various traps will allow evaluating the influence of single weather parameters on beetle flight directions and distances depending on the topographic situation of the locality. By combining the data from different sites under different topographic and weather conditions, a model will be developed which may be used to forecast the beetle’s dispersal from infested sites to vulnerable sites predisposed for new infestation by including weather forecast data for the near future.
