The beech leaf mining weevil, Orchestes fagi, is a pest of beech in Europe and is now established in Nova Scotia in the Halifax area as well as Cape Breton. Both adults and larvae damage the foliage of American beech, making the crowns appear scorched when damage is severe. The adults overwinter in cracks and crevices of beech boles infested with beech bark disease and under scales of other trees as well (e.g., maple, spruce) making firewood movement a potential pathway for artificial spread. I will briefly describe highlights of recent research on biology, survey and control of the beech weevil in Nova Scotia.
