Abstract

Mountain pine beetles (Dendroctonus ponderosae Hopkins) were released and recaptured using pheromone-baited Lindgren traps at various distances from the release point to determine the effects of distance on trapping effectiveness. Very few beetles were recaptured more than 500 m from the point of release, although this may have been due to interference by intervening traps. Trapping effectiveness depended on trap location, date of release, wind speed and distance from the point of release. Between 2 and 3% of the released beetles were recaptured in total.

Key words: Mountain pine beetle; pheromone trapping; dispersal
