Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the "First International Symposium on Insect Pheromones," which was held at Wageningen, The Netherlands, from March 6 to March 11, 1994. Eighty participants from 17 countries attended the symposium, which turned out to be a unique forum for the exchange of the latest worldwide findings on insect pheromones, an opportunity to discuss and debate unsettled issues, and a mechanism to define new directions in pheromone research and foster interdisciplinary collaborations. The meeting comprised five sessions representing the breadth of disciplinary interest in pheromones, a typical charac teristic of this research area. In the sessions the following topics were presented: (1) control of pheromone production (organized by W. L. Roelofs), (2) sensory processing of pheromone signals (T. L. Payne), (3) neuroethology of pheromone mediated responses (T. C. Baker), (4) use of pheromones in direct control (A. K. Minks and R. T. Card6), and (5) evolution of pheromone communication (c. LOfstedt). All sessions started with a series of 30-minute lectures, after which ample time was reserved for discussion. In each session some participants were asked to serve as discussants and to initiate and stimulate discussion, and a rapporteur was recruited to make notes of these discussions and to summarize the general trends emerging from the session. The general program ming of the symposium was in the hands of R. T. Carde, A. K. Minks, and T. L. Payne.

Book excerpt: "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." --

Download or read book A History of Forest Entomology in the Intermountain and Rocky Mountain Areas 1901 1982 written by Malcolm M. Furniss and published by . This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This account spans the time from A.D. Hopkins' trip to the Black Hills, SD, in 1901 to my retirement in 1982. The focus is on personnel and the work of the Division of Forest Insect Investigations, USDA, and the Forest Service experiment stations in the Rocky Mountain and Intermountain areas. Information for the Intermountain and Northern Rocky Mountain station areas is derived from my experience there and as chairman of the history committee of the Western Forest Insect Work Conference (WFIWC). Information on the Rocky Mountain and Southwestern station areas came primarily from the WFIWC archives, University of Idaho, and from retired forest entomologists.
Download or read book Techniques in Pheromone Research written by Hans E. Hummel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been suffi ciently ironed out to permit students to master the manipulations in a few lab oratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomo logical problems, and (3) to describe experiments which may be applicable for use in biology laboratory co~rses.
Download or read book Forest Insects written by Alan A. Berryman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a general text for undergraduates studying the manage ment of forest insect pests. It is divided into four parts: insects, ecology, manage ment, and practice. Part I, Insects, contains two chapters. The first is intended to provide an overview of the general attributes of insects. Recognizing that it is impossible to adequately treat such a diverse and complex group of organisms in such a short space, I have attempted to highlight those insectan characteristics that make them difficult animals to combat. I have also tried to expose the insects' weak points, those attributes that make them vulnerable to manipulation by human actions. Even so, this first chapter will seem inadequate and sketchy to many of my colleagues. Ideally, this book should be used in conjunction with a laboratory manual covering insect anatomy, physiology, biology, behavior, and classifica tion in much greater depth-in fact, this is how I organize my forest entomology course. It is hoped that this first chapter will provide nonentomologists with a general feel for the insects and with a broad understanding of their strengths and weaknesses, while Chapter 2 will provide a brief overview of the diverse insect fauna that attacks the various parts of forest trees and their products.
