Environmental Effects on Host Selection and Dispersal of Mountain Pine Beetle by Mary Lynn Reid Pdf

This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. It summarizes the results of a study on the landscape variation in lodgepole pine constitutive defences, primarily measured as resin production, but also as phloem monoterpene concentration. The response of pioneer mountain pine beetles to those defences is reviewed, measured by experimentally placing beetles on trees and by attacks of free-flying beetles; effects of beetle quality (size, condition) on the beetles' responses are also examined. Finally, the results on the dispersal of mountain pine beetles through a mature lodgepole pine stand and a burned stand are presented.--Includes text from Government of Canada publications site and from document.

Biology and Control of the Western Pine Beetle by John Martin Miller,Frederick Paul Keen Pdf

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.

Forecasting Mountain Pine Beetle Overwintering Mortality in a Variable Environment by Barry Cooke Pdf

Climatic fluctuations are known to be a critical factor in the risk of mountain pine beetle (MPB) outbreaks and overwintering mortality caused by cold exposure is one of the key factors in the population dynamics of MPB. A conceptual model of MPB overwintering survival was developed based on supercooling point (SCP) estimation, where MPB cold tolerance varies daily as a function of daily fluctuations in air and tree phloem temperatures. The model described MPB overwintering survival as exhibited by MPB in the southern Rocky Mountains of the U.S. during the early 1990s. The purpose of the project described in this report was to test this model for use in the northern Rocky Mountains of Canada, and to move quickly toward development of an operational tool that provincial pest managers, especially those in Alberta Sustainable Resource Development, could use with confidence.--Includes text from document.
