Recent Discoveries Concerning the Biology of the Mountain Pine Beetle and their Effect on Control in Western White Pine Stands
Abstract:This paper is a summary of the studies during 1930, 1931 and 1932 in the white pine stands of eastern Washington and northern Idaho, of the biology and habits of Dendroctonus monticolae Hopk. Previous studies have never fully accounted for the rapid increase in the number of infested trees during outbreaks, nor have they adequately explained increases which have occurred subsequent to control work in several instances. Factual knowledge along such lines is essential to the efficient planning and execution of future control projects.
