Download or read book Use of the Multi Pher Trap to Monitor Spruce Budworm Populations written by Luc Joseph Jobin and published by Sainte-Foy, Québec : Forestry Canada, Quebec Region. This book was released on 1993 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Multi-Pher insect trap was first manufactured and marketed in 1984. In 1985, it was used in the development of a detection and monitoring system for the spruce budworm over a major part of the distribution area of the species in North America. From 1984- 89, 12 experiments to assess and optimize trap effectiveness were conducted in balsam fir stands infested by spruce budworm in the Gaspe Peninsula. Three models of the trap were compared and the number of males captured was considered an adequate measure of trap effectiveness. Testing compared lure brand and holder, insecticide, funnel, baffle, colour and trap placement, cleanliness, and holder.

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 Chemical Ecology of Insects written by William J. Bell and published by Springer. This book was released on 2013-11-27 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.
Download or read book Insect Chemoreception written by M.F. Ryan and published by Springer Science & Business Media. This book was released on 2002-01-31 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume encompasses and unites all the major topics relating to Insect Chemoreception. Part 1 addresses topics such as plant/insect interactions, pheromones, ultrastructure, electrophysiology and the biochemistry of chemoreceptors. Part 2 embraces applications of plant chemicals and cultivars in insect pest control, host plant resistance and pheromones. A concluding chapter discusses the scope and potential of genetic engineering. This comprehensive account of the major aspects of sustainable insect pest control, together with the key references cited, will point the way to relevant research projects, and provide an up-to-date awareness of recent developments in the field. Audience: Graduate students and researchers in insect chemoreception, chemical ecology and sustainable pest control.
Download or read book Biological Control Measures of Success written by G. Gurr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.
Download or read book Bark and Wood Boring Insects in Living Trees in Europe a Synthesis written by François Lieutier and published by Springer Science & Business Media. This book was released on 2007-08-24 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, a synthesis on the research work done in Europe on all Bark And Wood Boring Insects In Living Trees (BAWBILT) is presented. As final product of a four-year research project gathering together 100 scientists from 24 countries, the book is the fruit of a real collective synthesis in which all European specialists have participated. It reviews and comments on all the European literature, while considering the biological (trees, insects, associated organisms, and their relationships) and forest management aspects. However, although focused on the European forest, it also compares the available information and interpretations to those concerning similar species in other continents. It ends with propositions of research priorities for Europe. The book is directed to all scientists and students concerned with forest entomology and ecology, as well as to forest managers and all scientific public interested in forest biology.
