Abstract
During May and June more overwintering adults of Hylurgopinus rufipes (Eichhoff) were caught on American elms, Ulmus americana L., that had been pruned than on those that were not pruned. Fewer beetles were caught on pruned elms whose wounds were treated with dressing compound than on pruned elms with no wound dressing. The number of H. rufipes that were caught also varied with height above the ground; more beetles were caught at 3 m on elm trunks than at 2 or 4 m. After mid-July, there was no significant difference in the number of summer-emerging H. rufipes caught on pruned elms compared with that on unpruned elms.
