Safranyik and published by Canadian Museum of Civilization/Musee Canadien Des Civilisations. This book was released on 2009 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides the results of a specific part of an eight year study on spruce beetle populations, begun in 1972. In this part of the study, which was conducted from 1975 to 1979, emerged spruce beetles were collected each year and chosen at random from the collections to be examined for the presence of filamentous fungi, yeasts, bacteria, mites, and nematodes. The objective of this section of the study was to provide a survey of the presence and relative abundance of these organisms associated with newly emerged adult spruce beetles.--Includes text from document.

Book excerpt: In 1972 a field study of spruce beetle (Dendroctonus rufipennis) population dynamics was established in central British Columbia (BC) in two adjacent timber harvesting areas. Data from the 7-year field study was analysed with respect to the effects of spruce windthrow, stumps, and other logging residue on variation in the following factors of spruce beetle populations: adult emergence, adult size and sex ratio, brood development, and brood survival.--Includes text from document.

Available in PDF, EPUB and Kindle. Book excerpt: The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.
