Book excerpt: This field handbook has been prepared to provide information on western forest insects. The discussions are limited to the insects and the problems which they raise in the management and protection of the forests of the Western States, although the general principles of control are applicable to other forest regions as well. It is hoped that the information assembled will add timber owners and foresters in recognizing the work of important western forest insects, in applying suitable control measures, or in adjusting forest practices so as to reduce losses from this source to the lowest possible point.

Download or read book Harry E. Burke and John M. Miller, Pioneers in Western Forest Entomology written by Boyd E. Wickman and published by . This book was released on 2005 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This history was compiled from the memoirs, diaries, and other personal documents of the two forest entomologists in charge of the first forest insect laboratories on the west coast. It traces the lives of the two pioneers from 1902 to 1952 as they pursued their careers in the USDA Bureau of Entomology, Division of Forest Insect Investigations. Cooperative bark beetle control projects with the USDA Forest Service, Park Service, and private timber owners guided much of their early activities. Later, when the laboratories were located on university campuses, cooperative research was undertaken with Forest Service Research Stations. The focus shifted to more basic research and, particularly, studies on the silvicultural management of bark beetle populations.

Available in PDF, EPUB and Kindle. Book excerpt: This publication is a companion volume to Miscellaneous Publication 273, Insect Enemies of Western Forests, but Keen. Its purpose is to treat in a practical manner the more important forest insects in that part of the United States lying east of the Great Plains or treeless areas, roughly the 100th meridian. There is necessarily some overlapping of the eastern and western regions, particularly in the more arid parts of Texas and the Southwest and along the watercourses traversing the Great Plains where the eastern hardwoods extend westward.

Download or read book The Forest Ecosystem of Southeast Alaska written by John S. Hard and published by . This book was released on 1974 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southeast Alaska's remaining virgin forests have few insect pests. The black-headed budworm and the hemlock sawfly, both western hemlock defoliators, are the most important species. They kill some trees, kill tops in others, and cause growth loss, but stands survive their attacks. Extensive conversion of virgin stands to second growth may result in an increase in pest problems as it has in similar areas such as coastal British Columbia. ??Widespread use of insecticides to control major outbreaks is not practical because of risk of contaminating salmon-spawning and trout-rearing streams; but insecticide use may be justified in local, high value areas. Weather, diseases, and parasites control outbreaks naturally. Damage-prone stands should be identified and harvested before insect attack or salvage-logged following outbreaks. Ideally, second-growth stands should be managed for resistance to insect pests.

Download or read book Forest Entomology written by William Ciesla and published by John Wiley & Sons. This book was released on 2011-03-08 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are the most abundant and diverse organisms that inhabit our planet and are found in all the world’s forest ecosystems. Many feed and/or breed on parts of trees. Some perform important functions, such as pollination or break-down of dead vegetation. Others weaken, deform or kill trees, and compete with humans for the many goods and services that trees and forests provide. Forest Entomology: A Global Perspective examines forest insects in a global context and reviews their dynamics, interactions with humans and methods for monitoring and management of species that damage forests. Also provided are 235 profiles of forest insects, worldwide. A series of tables provides summaries of the distribution and hosts of many more species. Included are those that damage forests, others that are simply curiosities and some that are beneficial. This book is designed as a reference for students, practicing foresters and forest health specialists, especially for those who work internationally or are concerned with species that have the potential to expand their ranges via international trade, travel or environmental changes.

This book was released on 2013-06-29 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a great honor and indeed a privilege for me to write the Foreword to this book, the first of its kind from the Forest Products Research Institute The study of forest insects is now becoming a matter of great concern to many people all over the world because insects damage the already depleted forests and forest resources. In Ghana very little interest was shown in the insects of forest trees and products. But as forest practices have become more intensive so also have the pests on the crops increased and the damage caused increased to alarming proportions. Foresters are now becoming in creasingly aware of the immense havoc that some of these insects can cause. To aid the fight against the pests they have to be fully identified and studied so that effective control measures can be implemented. It is in an effort to bridge this gap in our knowledge that one welcomes this book by Professor Michael R. Wagner, Dr. S.K.N. Atuahene and Dr.
