Abstract:This article is a reply to one by A. R. Gobeil in which he questioned whether the eastern spruce bark-beetle can be classified as economically injurious. The author disagrees with this view and emphasizes the damage caused by the insect not only through the amount of material destroyed but in adversely modifying the composition of the forest, in increasing the fire hazard, and in making logging more difficult. The importance of sound silvicultural management in preventing serious outbreaks is stressed.
