This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years many of the conventional methods of insect control by broad spectrum synthetic chemicals have come under scrutiny because of their unde sirable effects on human health and the environment. In addition, some classes of pesticide chemistry, which generated resistance problems and severely affected the environment, are no longer used. It is against this background that the authors of this book present up-to-date findings-relating to biochemical sites that can serve as targets for developing insecticides with selective prop erties, and as the basis for the elucidation of resistance mechanisms and countermeasures. The book consists of eight chapters relating to biochemical targets for insec ticide action and seven chapters relating to biochemical modes of resistance and countermeasures. The authors of the chapters are world leaders in pesti cide chemistry, biochemical modes of action and mechanisms of resistance. Biochemical sites such as chitin formation, juvenile hormone and ecdysone receptors, acetylcholine and GABA receptors, ion channels, and neuropeptides are potential targets for insecticide action. The progress made in recent years in molecular biology (presented in depth in this volume) has led to the iden tification of genes that confer mechanisms of resistance, such as increased detoxification, decreased penetration and insensitive target sites. A combina tion of factors can lead to potentiation of the resistance level. Classifications of these mechanisms are termed gene amplification, changes in structural genes, and modification of gene expression.

Download or read book Insecticides with Novel Modes of Action written by Isaac Ishaaya and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of insect control looked very bright in the 1950s and 1960s with new insecticides constantly coming onto the market. Today, however, whole classes of pesticide chemistry have fallen by the wayside due to misuse which generated resistance problems reaching crisis proportions, severe adverse effects on the environment, and public outcry that has led to increasingly stricter regulation and legislation. It is with this background, demanding the need for safer, environmentally friendly pesticides and new strategies to reduce resistance problems, that this book was written. The authors of the various chapters have a wealth of experience in pesticide chemistry, biochemical modes of action, mechanism of resistance and application, and have presented concise reviews. Each is actively involved in thedevelopment of new groups of pesticide chemistry which led to the development of novel insecticides with special impact in controlling agricultural pests. Emphasis has been given to insecticides with selective properties, such as insect growth regulators hormone mimics, ecdysone agonists), (chitin synthesis inhibitors, juvenile chloronicotinyl insecticides (imidacloprid, acetamiprid), botanical insecticides (neem, plant oils), pymetrozine, diafenthiuron, pyrrole insecticides, and others. The importance of these compounds, as components in integrated pest management programs and in insecticide resistance management strategies, is discussed. The data presented are essential in establishing new technologies and developing novel groups of compounds which will have impact on our future agricultural practices.

Download or read book Native Speaker written by Chang-rae Lee and published by Penguin. This book was released on 1996-03-01 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: ONE OF THE ATLANTIC’S GREAT AMERICAN NOVELS OF THE PAST 100 YEARS The debut novel from critically acclaimed and New York Times–bestselling author of On Such a Full Sea and My Year Abroad. In Native Speaker, author Chang-rae Lee introduces readers to Henry Park. Park has spent his entire life trying to become a true American—a native speaker. But even as the essence of his adopted country continues to elude him, his Korean heritage seems to drift further and further away. Park's harsh Korean upbringing has taught him to hide his emotions, to remember everything he learns, and most of all to feel an overwhelming sense of alienation. In other words, it has shaped him as a natural spy. But the very attributes that help him to excel in his profession put a strain on his marriage to his American wife and stand in the way of his coming to terms with his young son's death. When he is assigned to spy on a rising Korean-American politician, his very identity is tested, and he must figure out who he is amid not only the conflicts within himself but also within the ethnic and political tensions of the New York City streets. Native Speaker is a story of cultural alienation. It is about fathers and sons, about the desire to connect with the world rather than stand apart from it, about loyalty and betrayal, about the alien in all of us and who we finally are.
Download or read book New Types of Persistent Halogenated Compounds written by Jaakko Paasivirta and published by Springer. This book was released on 2008-01-26 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.
Download or read book Effect Directed Analysis of Complex Environmental Contamination written by Werner Brack and published by Springer. This book was released on 2013-05-29 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today more than 5 million chemicals are known and roughly 100,000 of them are frequently used, with both numbers rising. Many of these chemicals are ultimately released into the environment and may cause adverse effects to ecosystems and human health. Effect-directed analysis (EDA) is a promising tool for identifying predominant toxicants in complex, mostly environmental mixtures combining effect testing, fractionation and chemical analysis. In the present book leading experts in the field provide an overview of relevant approaches and tools used in EDA. This includes diagnostic biological tools, separation techniques and advanced analytical and computer tools for toxicant identification and structure elucidation. Examples of the successful application of EDA are discussed such as the identification of mutagens in airborne particles and sediments, of endocrine disruptors in aquatic ecosystems and of major toxicants in pulp and paper mill effluents. This book is a valuable, comprehensive and interdisciplinary source of information for environmental scientists and environmental agencies dealing with the analysis, monitoring and assessment of environmental contamination.
Download or read book Chitin and Benzoylphenyl Ureas written by James E. Wright and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: The opportunity to explore a developing new technology in a single biological system, chitin, from the molecular basis and with the inter relationship of the utilization of benzoylphenyl ureas in effective pest agroecosystem management strategies, represents a new evolution for integration of knowledge in this highly complex area. The degree of great progress and interest in the understanding of the interaction of chitin uItrastructures, biochemistry, and the unique ben zoylphenyl ureas attest to the timeliness of this effort. The purpose of the book that follows is to provide up-to-date and well illustrated details of current research knowledge including the latest of research results. The combination of the basic to the applied aspects rarely occurs specifically at the levels presented by the international contributors within. The original contributions composed the symposium "Chitin and Ben zoylphenyl Urea" organized by the co-editors at the International Con gress of Entomology in Hamberg, Germany, August 1984. We extend our appreciation to everyone who made the conference an outstanding success and highlight of the Congress, as well as making this book possible. We thank the authors, especially for their excellent international presenta tions, discussions, and preparation of the manuscripts. The knowledge evolved from many areas in chitin research, as well as the intricate com plexity of successful utilization of specific knowledge involving benzoylp henyl ureas in system management strategies for insects will continue to be in the forefront throughout the world's agroecosystems; and hopefully this book will enhance further research and development.
Download or read book Insect Hormones and Bioanalogues written by K. Slama and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of organic insecticides in the agrotechnical praxis resulted in a great and unexpected progress in the control of insect pests, and was of a great economical value all over the world. The widespread application of these agents, however, is also accompanied by negative effects. The principal drawback of classical insecticides consists in the lack of their specificity, the useful insects being killed together with insect pests. Furthermore, the broad-scale application for many years led to the formation of more resistant insect strains requiring higher and higher doses of insecticides. The residues of the mostly used chlorinated compounds accumulate in human and animal foods producing directly or indirectly harmful effects in human sub jects. The critical situation led in many developed countries to the restriction in the usage of some types of classical insecticides. Under these circumstances it is quite natural that novel routes for the control of insect pests are investigated. In this connection, attention has been paid especially to the insect endocrinology and insect hormones which regulate the admirable and in many regards specific development from the egg to the adult insect. The recent successful discoveries in this field are thus in close relation to the practical requirements. Isolation and identification of moulting hor mones and juvenile-hormone-like naturally occurring substances not only made possible an exact investigation of their physiological effects but also stimulated the chemical research.
Download or read book Sublethal and Chronic Effects of Pollutants on Freshwater Fish written by Rudolf Müller and published by Wiley-Blackwell. This book was released on 1994-01-01 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen much greater emphasis placed on the monitoring and measurement of sublethal aspects of pollution on fish. Tests and subsequent measurements have been made over the whole range of biological organisation – from the subcellular to changes at community structure level. Studies at the lower levels attract considerable scientific interest but, in many cases, it is still difficult to interpret the results of tests in terms of predicted harmful effects on individual fish. Conversely, it has been difficult to attribute the effects measured at higher levels to specific pollutants. This major new volume of immense scientific importance to fisheries managers, fish biologists, ecotoxicologists and those working in the area of fisheries and pollution, contains thirty–two papers presented at the Symposium hosted by the European Inland Fisheries Advisory Commission. Contributions come from an international team of distinguished experts and, together, the papers represent a detailed overview of work which is currently being undertaken in this area. Unlike many Symposia which simply report proceedings, this volume integrates the results of various areas of research and offers solid recommendations for future research and control.

Download or read book Alpine Waters written by Ulrich Bundi and published by Springer Science & Business Media. This book was released on 2010-02-04 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the world’s mountains are rich in water and, as such, play a pivotal role in the global water cycle. They provide water for diverse human uses and ecosystems. Growing water demands as well as climate change will lead to ever-increasing pressure on mountain waters. Overcoming water-use conflicts and maintaining the ecological functioning of mountain waters presents a highly challenging task and is indispensable for sustainable development. This book extensively portrays the highly diverse attributes of mountain waters and demonstrates their paramount importance for ecological and societal development. The extensive summaries on the scientific basics of mountain waters are supplemented with considerations on the diverse water uses, needs for management actions, and challenges regarding sustainable water management. This overview concerns not only the mountain areas themselves but also downriver reaches and their surrounding lowlands, and, therefore, the relationship between mountain and lowland water issues.
