Book excerpt: Excerpt from Estimating Engelmann Spruce Beetle Infestations in the Central Rocky Mountains Newly infested trees are difficult to recognize even at short distances, because pitch tubes at the points of attack generally are very small or absent. Each tree must be inspected carefully around the base for red dust from borings. Engelmann spruce is the primary host of the beetle although lodgepole pine and blue spruce also are attacked uhen mixed with Engelmann spruce. Although many lodgepole pines die, the insect broods usually do not develop to maturity. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
