Response of the Bronze Birch Borer to Pruning Wounds on Paper Birch

Abstract

Healthy appearing paper birch trees were pruned at the beginning of the bronze birch borer's emergence period. Some wounds were left exposed while others were treated with a commercial wound dressing. Bronze birch borer adults, particularly females, were attracted to fresh pruning wounds on paper birch. Treating the pruning wounds with a wound dressing did not reduce the wound's attractiveness to the borers.
