Download or read book Outbreaks of the Western Spruce Budworm in the American Northern Rocky Mountain Area from 1922 Through 1971 Classic Reprint written by Philip C. Johnson and published by Forgotten Books. This book was released on 2017-11-08 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Outbreaks of the Western Spruce Budworm in the American Northern Rocky Mountain Area From 1922 Through 1971 Research on the western spruce budworm in recent years has been concerned chiefly with its population dynamics, behavior, genetic characteristics, and chemical control. Few investigations have been directed specifically to its relationship with its host tree species or to the patterns of its outbreaks. Such studies must ultimately be made. Fortunately, much basic information useful for these studies exists in numerous reports that document details of the chronology, geographic distribution, and general severity of many of the budworm outbreaks in the two Forest Service Regions. The general purpose here is to review this information (mostly unpublished) as a background for continuing biological and ecological studies of this important forest insect pest and as an appropriate reference for investigations into its epidemiology. Specifically, our intent here is to (1) consolidate, summarize, and present information about the location, host types, duration, effects, and measures for control applied in past outbreaks; (2) discuss factors thrt appear to relate to the location, duration, and probable effect of budworm outbreaks in the the Regions; and (3) identify problems for further study to more accurately assess the impact possibilities of outbreaks of the budworm in host forests managed for specific uses.

Download or read book Biological Control Measures of Success written by G. Gurr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.

Available in PDF, EPUB and Kindle. Book excerpt: Vector-borne infectious diseases, such as malaria, dengue fever, yellow fever, and plague, cause a significant fraction of the global infectious disease burden; indeed, nearly half of the world's population is infected with at least one type of vector-borne pathogen (CIESIN, 2007; WHO, 2004a). Vector-borne plant and animal diseases, including several newly recognized pathogens, reduce agricultural productivity and disrupt ecosystems throughout the world. These diseases profoundly restrict socioeconomic status and development in countries with the highest rates of infection, many of which are located in the tropics and subtropics. Although this workshop summary provides an account of the individual presentations, it also reflects an important aspect of the Forum philosophy. The workshop functions as a dialogue among representatives from different sectors and allows them to present their beliefs about which areas may merit further attention. These proceedings summarize only the statements of participants in the workshop and are not intended to be an exhaustive exploration of the subject matter or a representation of consensus evaluation. Vector-Borne Diseases : Understanding the Environmental, Human Health, and Ecological Connections, Workshop Summary (Forum on Microbial Threats) summarizes this workshop.
