Book excerpt: The insects presented in this book are among the most common and the most destructive found on what are considered to be the most important tree species; namely, spruce, larch, pine, oak, maple and poplar.It is intended for use by both scientists and by practising foresters. To make the information contained in this volume more easily accessible, insects are grouped according to the tree species that they attack rather than by their entomological classification, and, for this reason, insects found on a given tree species are presented in the same chapter. The annual reports of the Forest Insect and Disease Survey have provided most of the information on history of outbreaks that is found in the text.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Some Insects Injurious to Forests: The Western Pine-Destroying Barkbeetle The object of this paper is to give available information on. This insect and methods of combating it, with special reference to the results of investigations by the writer during the summer of 1905 in central Idaho. The need of the investigations was suggested in a letter dated August 10, 1904, from Mr. Gifford Pinchot, forester of the U. S. Department of Agriculture, to Dr. L. 0. Howard, chief of the Bureau of Entomology, as follows: I learn from the Payette Lumber and Manufacturing Company, one of the Weyerhaeusers, whose land lies on the Payette River north of Boise, that the pine in their holdings is said to be dying from the attacks of insects. If it were possible for you to assign Doctor Hopkins, or one of his assistants, to make examination of this region, unless it has already been done, I should greatly appreciate it, and I should likewise appreciate your sending to Mr. Edgar M. Hoover, general manager of that company at Boise, any information you may have bearing on this subject. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insects Injurious to Forests and Forest Products: Damage to Telephone and Telegraph Poles by Wood-Boring Insects The writer on October 3, 1909, inspected some chestnut telegraph poles which had been standing for about twelve years on New York avenue, in Washington, D. C. The poles had been taken down under orders from the city authorities, which necessitated the placing of wires in conduits under ground, and they had been lying in piles for about a month before they were inspected. The chestnut telephone pole borer had been working in the base of the poles, and white ants, or termites, were associated with them. Twelve out of the 103 poles examined had been damaged, some more seriously than others. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
