USDA Forest Service, Forest Insect and Disease Leaflet 122, 5 pp.
In the western United States, the pine engraver is a significant and frequent pest of ponderosa pine. In some localities it is also an important killer of lodgepole and Jeffrey pines and can be a serious pest in plantations of jack and red pines in the Midwest. In rare instances it may infest pinyon, Coulter, limber, sugar, western white, southwestern white pines, and probably most other pine species occurring within its range.
