DOWNLOAD EBOOKThis 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.
