Download or read book Fitness and Pathogenicity of the Fungi Associated with the Mountain Pine Beetle and Other Secondary Beetles in Green Attack written by Colette Breuil and published by . This book was released on 2008 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (MPB), Dendroctonus ponderosae Hopkins, is the most destructive bark beetle in western Canada. Fungi, particularly those of the Ophiostomatoid group, can aid the beetle in successfully attacking and colonizing trees. This report concerns experiments to characterize the instraspecific variation in virulence indicators of ophiostoma clavigerum, and to compare two time periods for growth inside trees in relation to virulence indicators. The researchers examined the optimal temperature and pH for growth and the effects of fatty acids, terpenes and oxygen on the growth of the different strains.--Includes text from document.

Book Synopsis The Pathogenicity of Blue-stain Fungi on Lodgepole Pines Attacked by Mountain Pine Beetle by : Richard Grant Ballard

This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the western regions of North America, mountain pine beetle, Dendroctonus ponderosae Hopk., infestations take a tremendous toll of pines , especially lodgepole pine, Pinus contorta Dougl. var. latifolia Engelm.. Mass attack by the beetles is a devastating event for the trees. As well as girdling the tree, a massive inoculation of blue stain fungus "complex" (composed of several species of Ceratocystis, numerous yeasts and other mycelial fungi) is made beneath the bark. These fungi colonize and destroy the parenchyma tissue system of the host sapwood, primarily the ray parenchyma and resin duct epithelium. A blue stain is produced in the sapwood as a consequence of destruction of the sapwood parenchyma. The stain develops inward through the sapwood, and the transpiration stream is cut off. As more and more sapwood is stained, foliar water stress begins to increase. Foliage however, remains green and apparently healthy for up to 10 months after inoculation. When spring bud break begins the year following beetle attack, terminal buds of blue-stained trees begin to expand, then abort. Soon after, the needles of these trees fade to a reddish brown color. Transpiration stream disruption was not caused by penetration of tracheids by fungal hyphae; tyloses were not observed; nor was microconidial blockage of bordered pits seen. Though resin duct epithelium was eventually destroyed, little resin soaking was observed in the initial blue stained regions. Many bordered pits of tracheids in stained regions appeared to be aspirated, suggesting introduction of embolisms.

This book was released on 2005 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report highlights past delivery of the land-based programs and progress of mountain pine beetle research during 2003 & 2004 by the Mountain Pine Beetle Initiative, a six-year program established to address the mountain pine beetle epidemic in western Canada and to reduce the risk of future such epidemics. After an introduction on the epidemic and the Initiative, the report summarizes the accomplishments of the Private Forestlands Rehabilitation Program, the Federal Forestlands Rehabilitation Program (First Nations, National Parks, and Other Federal Forestlands components), and the research & development program (including research on ecology, forest economics, socio-economic processes & risk reduction). Finally, the next steps in the land-based and research & development programs are discussed.

Download or read book Decay Fungi and Associated Rates of Decay in Standing Trees Killed by Mountain Pine Beetle written by Colette Breuil and published by . This book was released on 2008 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. The purpose of this report is to identify and characterize the fungal species that may potentially damage wood and decrease its market values. It focuses on the characterization of 40 different basidiomycetous fungi that were isolated form 12 different sites across British Columbia. Fungi were isolated from mountain pine beetle-infested lodgepole pine trees in green, red, and grey stages from each of the 12 sites.--Includes text from Government of Canada publications site and from document.
Book Synopsis Considering the Effectiveness of Mountain Pine Beetle Mitigation Strategies by : Nicholas C. Coops
Download or read book Considering the Effectiveness of Mountain Pine Beetle Mitigation Strategies written by Nicholas C. Coops and published by . This book was released on 2008 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the broad range of mitigation strategies associated with the management of mountain pine beetle (Dendroctonus ponderosae Hopkins), including methods that are currently utilized or proposed for controlling beetle populations, the manner in which the effectiveness of these approaches is monitored and assessed and, finally, the role that remotely sensed data may play in a large-area monitoring system. To this end, the authors first review the goals of effectiveness monitoring and introduce a general classification system to clarify the purpose and practice of efficacy monitoring. Based on these principles, the review is then structured around effectiveness evaluations for managing forest pests, primarily mountain, southern, and western pine beetles throughout North America. These evaluations are grouped by management strategy: silvicultural treatments; prescribed burns; and the use of attractants, repellants, and insecticides. Finally, the authors propose the use of remotely sensed data as a complementary tool for monitoring changes in the extent and severity of mountain pine beetle damage across large areas.--Document.
Book Synopsis Mountain Pine Beetle Attack in Ponderosa Pine: Comparing Methods for Rating Susceptibility by : David C. Chojnacky
Download or read book Mountain Pine Beetle Attack in Ponderosa Pine: Comparing Methods for Rating Susceptibility written by David C. Chojnacky and published by . This book was released on 2000 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two empirical methods for rating susceptibility of mountain pine beetle attack in ponderosa pine were evaluated. The methods were compared to stand data modeled to objectively rate each sampled stand for susceptibly to bark-beetle attack. Data on bark-beetle attacks, from a survey of 45 sites throughout the Colorado Plateau, were modeled using logistic regression to estimate the probability of attack on individual trees from tree and stand variables. The logistic model allowed flexibility to easily scale results up to a stand level for comparison to the empirical methods. The empirical method, developed by Munson and Anhold, most closely correlated to the logistic regression results. However, the Munson/Anhold method rated all 45 study sites as either moderately or highly susceptible to bark-beetle attack, which raises concern about its lack of sensitivity. Future work on evaluating risk of bark-beetle impact should consider more than stand characteristics.

Book Synopsis Ponderosa Pine Mortality Resulting from a Mountain Pine Beetle Outbreak by : William F. McCambridge
Download or read book Ponderosa Pine Mortality Resulting from a Mountain Pine Beetle Outbreak written by William F. McCambridge and published by . This book was released on 1982 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1965 to 1978, mountain pine beetles killed 25% of the pines taller than 4.5 feet in a study area in north-central Colorado. Average basal area was reduced from 92 to 58 square feet per acre. Mortality increased with tree diameter up to about 9 inches d.b.h. Larger trees appeared to be killed at random. Mortality was directly related to number of trees per acre and presence of dwarf mistletoe, but not to site index, elevation, and percent Douglas-fir in the stand.
