Available in PDF, EPUB and Kindle. Book excerpt: This publication reviews the results of research on the western pine beetle up to July 1, 1952. It shows the progress that has been made in over a half-century of study of this one bark beetle. It also records the trials and errors--the research that ran into blind alleys. The record of this pioneer effort in the field of forest entomology in the United States should be of great help to research workers who are faced with similar problems.

Available in PDF, EPUB and Kindle. Book excerpt: Nearly 70 years of research and application are reviewed and assessed. Results of direct control projects can be characterized as generally effective, temporary, quite variable, and unpredictable in reducing subsequent tree mortality. Some causes of this characterization are variable and difficult stand conditions and logistics, lack of good beetle population measurements and prediction, unknown attributes of tree and stand dynamics and of beetle population dynamics, and unforeseen post-application factors. The control method used did not appreciably change this characterization: fell-peel-bum, salvage logging, penetrating oil, residual toxic sprays, or attractive pheromones. Use of attractive pheromones was never thoroughly analyzed, and use of baited toxic trap trees was never adequately tested; both should be done.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Biology and Control of the Western Pine Beetle: A Summary of the First Fifty Years of Research This beetle undoubtedly was a factor in the ecology of ponderosa pine stands long before it became known to science. Pine stands that approached maturity were thinned by beetle epidemics, and new trees grew up to replace those that were killed. But, as long as Indians used the forest only for hunting grounds and the first white men were interested only in trapping and livestock ranching, no one cared what happened to the trees. The beetle was of no economic importance until the advent of the lumber industry. Then, as the realization developed that the supply of virgin pine stumpage was limited and that the beetle was hastening exhaustion of the old stands, the western pine beetle became a problem of great importance. The beetle upset logging programs and short ened the life of sawmill communities because it often became active in the woods before loggers reached the timber. It killed the very trees that the lumberman preferred to cut and mill into high quality lumber. Its work earned it the epithet The Pine Beetle Logging Company.
