| Résumé : | The Yellowheaded Spruce Sawfly (YHSS), Pikonema alskensis (Rohwer), (Hymenoptera : Tenthredinidae), defoliates spruce, Picea sp., throughout the Northern United States and Canada. The objectives of the document are to review and summarize the literature pertaining to YHSS, identify research gaps, and use existing information to develop long-term silvicultural management strategies for YHSS and perhaps similar defoliators. This research paper is divided into five major parts: 1) YHSS biology, distribution, hosts, and the signs and symptoms of damage; 2) Ecology and dynamics of YHSS populations; 3) Prevention and control tactics; 4) Survey procedures to assess YHSS populations and defoliation; and 5) Guidelines for selecting appropriate management strategies. |
