abstract
Reemergence of adult Ips avulsus from bark slabs occurred at 15-35C., with >95% of all beetles reemerging in the 25-35C range. Reemergence declined to 68% at 15C. The relationship of adult residence time to temperature formed a backward J-shaped curve, with the longest residence time occurring at 15C (84.4 d) and the shortest time at 32C (8.2 d). -from Authors
