Download or read book Low concentration of lindane plus induced attraction traps mountain pine beetle written by R. H. Smith and published by . This book was released on 1976 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain pine beetles were induced to attack lodgepole pine sprayed with 0.2 percent or 0.3 percent lindane emulsion. Large numbers of beetles were killed and fell into traps at the base of the tree. The few successfully attacking beetles caused the sprayed trees to remain attractive to beetles for about two months. The incidence of attacked trees in the immediate area of the sprayed trees was apparently reduced.

Book Synopsis Direct Control of Western Pine Beetle (Dendroctonus Brevicomis LeConte) by : Richard H. Smith
Download or read book Direct Control of Western Pine Beetle (Dendroctonus Brevicomis LeConte) written by Richard H. Smith and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly 70 years of research and application are reviewed and assessed. Results of direct control projects can be characterized as generally effective, temporary, quite variable, and unpredictable in reducing subsequent tree mortality. Some causes of this characterization are variable and difficult stand conditions and logistics, lack of good beetle population measurements and prediction, unknown attributes of tree and stand dynamics and of beetle population dynamics, and unforeseen post-application factors. The control method used did not appreciably change this characterization: fell-peel-bum, salvage logging, penetrating oil, residual toxic sprays, or attractive pheromones. Use of attractive pheromones was never thoroughly analyzed, and use of baited toxic trap trees was never adequately tested; both should be done.
Book Synopsis Surveying Marbled Murrelets at Inland Forested Sites by :
Download or read book Surveying Marbled Murrelets at Inland Forested Sites written by and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The marbled murrelet (Brachyramphus marmoratus), a seabird, nests in forested stands from southeast Alaska south to Santa Cruz, California. Because of this species' close association with old-growth forests, researchers and land managers need a method to assess murrelet distribution and use patterns throughout its range. This guide describes a standardized method for surveying marbled murrelets used by researchers in California and Oregon during 1988 and 1989. Transects can be used to assess activity patterns over large blocks of land, such as States or counties. Stationary counts using an intensive inventory method can be used to survey small acreages, such as individual timber sales. In addition to bird counts, vegetation and physical data should be collected at each census point. The guide includes a form that can be used to design studies and determine activity patterns and potential use.

Download or read book Proceedings of the Symposium on Sandalwood in the Pacific written by and published by . This book was released on 1990 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sandalwood (Santalum spp.) trees grow in a variety of climates around the world and are culturally and economically important to about 15 countries. Exploitation of the fragrant heartwood for carvings, oil, and incense in the past has led to the need to conserve and manage the genus. The first substantial logging of sandalwood in Hawaii in 150 years generated local controversy in 1988, uncovered misinformation and speculation about the genus, and eventually led to the symposium in 1990. Papers in this proceedings cover history, distribution, status, ecology, management, propagation, and use of sandalwood. A synthesis paper summarizes the state-of-knowledge of the symposium participants. Research is needed to fill gaps in information on various aspects of sandalwood in many of the countries where it grows.

Book Synopsis Management of Insect Pests with Semiochemicals by : Everett Mitchell
Download or read book Management of Insect Pests with Semiochemicals written by Everett Mitchell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perhaps the best expression of our intent in organ~z~ng this gathering is found in the definition of the word colloquy and its derivations. A gathering allowing familiar and informal conversation among colleagues with similar interests was our objective. Our motives were, of course, complex. Our main intent was not, however, to add to the list of books competing for the time of the scientific community at-large. However, while informality was our objective, a lasting document exists in the form of this publication of the presentations forming the skeleton on which we built less formal but meatier communications. We hope you can reconstruct on these bones a perception of the state of the art in the subject at hand. The members of this assemblage are specialists in one or more subdisciplines. Their formal communications are found in texts and journals appropriate to their broader disciplines. Often their friends alone are privy to their less formal thoughts, intuitions, hopes, and especially fears and failures. We hoped by organizing this colloquium to develop familiar and informal conversation among those most interested and active in applying semiochemicals in pest control. That community, like others also shared by Gainesville entomologists, has little or no formal organization or means for assemblage. We proposed on this and future occasions to offer the opportunity to this and similar groups to gather, though we do not presume too much to lead but rather to facilitate conversation.

Book Synopsis Forest Insects by : Alan A. Berryman
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.
