Book excerpt: Excerpt from Biology and Control of the Engelmann Spruce Beetle in Colorado From 1939 to 1951 the beetles destroyed billion board-feet of timber in western Colorado billion board-feet of Engelmann spruce and 500 million board-feet of lodgepole pine. This infestation was directly correlated with large numbers of trees that were blown down by a severe Windstorm on June 20, 1939. Some of the roots were still covered and functioning; others were completely severed. In many of the trees the bole was left standing with the crown blown off by the wind or broken off by falling trees. Apparently the beetles were present in endemic numbers and attacked the wind-damaged trees. By the summer of 1941 tremendous beetle populations had developed. The adults emerging from the wind-fallen and wind broken trees attacked standing green trees in the surrounding area.

Each tree must be inspected carefully around the base for red dust from borings.
