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.

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.

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.

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.
