The Western Bark Beetle Research Group by Anonim Pdf

"The compilation of papers in this proceedings is based on a symposium sponsored by the Insect and Diseases Working Group (D5) at the 2007 Society of American Foresters (SAF) convention in Portland, Oregon. The selection of topics parallels the research priorities of the Western Bark Beetle Research Group (WBBRG) (USDA Forest Service, Research and Development), which had been recently formed at the time of the symposium. Reflecting a unique partnership within the Forest Service, each paper was jointly prepared by a research scientist with the WBBRG and one or more entomologists with Forest Health Protection (USDA Forest Service, State and Private Forestry). Among these papers is a description of the currently elevated impacts of bark beetles in the Western United States; descriptions of the current state of knowledge of bark beetle response to vegetation management and also to climate change; discussions of the complex interactions of bark beetles and fire and of the complex ecological and socioeconomic impacts of infestations; an overview of the use of semiochemical (behavioral chemicals)-based technology for conifer protection; and a case study exemplifying efforts to assess risks posed by nonnative invasive bark beetles." --

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.

The Insatiable Bark Beetle by Reese Halter Pdf

"In our ever-warming world, trillions of indigenous bark beetles are killing billions of mature conifers throughout the forests of western North America and around the world, as they embark on their largest and most destructive feeding frenzy in modern times. In areas where cold temperatures traditionally prevented these insects from thriving, our once-healthy but now water-starved trees are becoming more and more vulnerable to the voracious appetites of these destructive pests. With aspects of both our environment and the economy at stake, Dr. Reese Halter's second RMB Manifesto provides information on the various types of beetles negatively impacting trees, descriptions of the ecosystems they currently inhabit, and an accessible look at the future humanity may face if we do not find ways to control greenhouse gas emissions and climate change, which are contributing factors to the ongoing spread of bark beetles." -- Publisher.

Western Bark Beetle Strategy by U.s. Forest Service Pdf

The Western Bark Beetle Strategy identifies how the Forest Service is responding to and will respond to the western bark beetle epidemic over the next five years. The extent of the epidemic requires prioritization of treatments, first providing for human safety in areas threatened by standing dead hazard trees, and second, addressing dead and down trees that create hazardous fuels conditions adjacent to high value areas. After the priority of safety, forested areas with severe mortality will be reforested with the appropriate species (Recovery). Forests will also be thinned to reduce the number of trees per acre and create more diverse stand structures to minimize extensive epidemic bark beetle areas (resiliency). This is a modest strategy that reflects current budget realities, but focuses our resources in the most important places that we can make a big difference to the safety of the American public. This strategy covers Fiscal Year (FY) 2011 through 2016. The western United States is experiencing the largest bark beetle outbreak in recorded history. Although western forests have experienced regular infestations throughout their history, the current epidemic is notable for its intensity, extensive geographic range, and simultaneous occurrence in multiple ecosystems. Since 1997, infestations of bark beetle species have escalated resulting in more than 41.7 million acres across all ownerships sustaining some level of conifer tree mortality. The past decade's epidemic is unprecedented in its environmental and social impacts. Various parts of the west experienced bark beetle population peaks at different times over the past 14 years. The Forest Service and the Natural Resources Conservation Service undertook a focused safety and recovery effort that was supported by approximately $138 million in agency and supplemental appropriations. From 2000 through 2009, the intermountain west experienced bark beetle caused mortality over an estimated 21.7 million acres across all ownerships, 17.7 million acres on national forests. The situation is further complicated by the fact that more and more people live and recreate in areas affected by the epidemic. This strategy incorporates our current understanding of available scientific research and presents a science-based path forward. The strategy will be achieved through well-defined goals, objectives, and action items, to address each of the three prongs of the bark beetle problem: human safety, forest recovery, and long-term forest resiliency. A successful approach to mitigating the impact of bark beetle must address actions for all three goals. While safety of human communities and infrastructure protection is paramount, there is also a critical need to restore the function and structure of our forests. Bark beetle is a natural part of our forests and as such will regularly impact our forests and the adjacent communities. Conducting resiliency treatments now and in the future will help minimize the potential for new outbreaks of bark beetles or make future outbreaks less intense. Although there has been much work accomplished to date for bark beetle management, this report focuses on the future. Honing our continuing response will seek to integrate various vegetation management activities across all jurisdictions to address bark beetle concerns in prioritized areas. Now is the time to act. Forest Service resources are in a position in which they can effectively respond and address this issue with increased effort. Public safety and economic impacts and costs will only increase if we delay.

Log Bioassay of Residual Effectiveness of Insecticides Against Bark Beetles by Richard Harrison Smith Pdf

Residual effectiveness of nine insecticides applied to bark was tested against western, mountain, and Jeffrey pine beetles. Ponderosa and Jeffrey pine trees were treated and logs cut from them 2 to 13 months later, and bioassayed with the three beetles. The insecticides were sprayed at the rate of 1 gal (3.8 l) per 40- or 80-ft2 (3.6 or 7.2 m2) bark surface at varying concentrations. Effectiveness of treatment was based on reduction in length of egg galleries 2 to 3 weeks after initiating bioassay. All chemicals were quite effective for 2 to 13 months, except for malathion and Imidan which were relatively ineffective, depending largely on concentration and application rate. On the basis of equivalent amounts of lindane, the ranking ofeffectiveness ofinsecticides tested was as follows: (a) on western pine beetle: decamethrin> permethrin> lindane> Reldan> Dursban Sumithion> Sevin; (b) on mountain pine beetle: decamethrin> permethrin> lindane> Dursban Reldan> Sevin> Sumithion; (c) on Jeffrey pine beetle: decamethrin> permethrin> lindane> Sevin. The residual effectiveness of lindane was about doubled by adding 2 percent molasses, and high pH of water reduced effectiveness of Sevin. Other application parameters had little effect.

Biology and Control of the Western Pine Beetle by John Martin Miller Pdf

Excerpt from Biology and Control of the Western Pine Beetle: A Summary of the First Fifty Years of Research This beetle undoubtedly was a factor in the ecology of ponderosa pine stands long before it became known to science. Pine stands that approached maturity were thinned by beetle epidemics, and new trees grew up to replace those that were killed. But, as long as Indians used the forest only for hunting grounds and the first white men were interested only in trapping and livestock ranching, no one cared what happened to the trees. The beetle was of no economic importance until the advent of the lumber industry. Then, as the realization developed that the supply of virgin pine stumpage was limited and that the beetle was hastening exhaustion of the old stands, the western pine beetle became a problem of great importance. The beetle upset logging programs and short ened the life of sawmill communities because it often became active in the woods before loggers reached the timber. It killed the very trees that the lumberman preferred to cut and mill into high quality lumber. Its work earned it the epithet The Pine Beetle Logging Company.
