    Abstract
    We discovered after some research that there had not been any comprehensive studies done on the mountain pine beetle, Dendroctonus ponderosae (Hopkins), infesting ponderosa pine, Pinus ponderosa (Laws), though it is mentioned extensively in the literature. The literature is extensive with analytical and statistical data concerning various aspects of the life cycle of D. ponderosae.and the nature of its infestation of P. ponderosa and other members of the genus Pinus. Our study attempts to correlate information found in the literature about this specific infestation problem, with an infestation occurring in the Grizzly Gulch area of the Helena National Forest, 2 miles south of Helena, Montana. We attempted to synthesize a general study on the life cycle of D. ponderosae in its attack on P. ponderosa, and did not stress definite numerical analyses, as we felt the literature adequate in this respect. A work somewhat along the same lines, is the excellent comprehensive study presented as a doctoral thesis by R.W. Reid in 1960 on D. monticolae (=D. ponderosae) in lodgepole pine near Radium, British Columbia. We borrowed extensively from his work and other excellent works done by researchers at the Northern Forest Research Centre at Edmonton, Alberta.We discovered after some research that there had not been any comprehensive studies done on the mountain pine beetle, Dendroctonus ponderosae (Hopkins), infesting ponderosa pine, Pinus ponderosa (Laws), though it is mentioned extensively in the literature.
