Abstract
The Black Hills beetle, Dendroctonus ponderosae Hopk. is the most destructive insect of ponderosa pine, Pinus ponderosa Laws., on the Dixie National Forest and in Bryce Canyon National Park in southern Utah. This beetle also attacks limber, whitebark, pinyon, lodgepole, bristlecone and Mexican white pines, and occasionally Englemann and blue spruces throughout its range in South Dakota, Wyoming, Colorado, Utah, northern Arizona and New Mexico. It seldom produces broods in spruces, because the parent and young brood are usually "pitched-out." This insect has been known to recur periodically in stands of overmature ponderosa pine.
