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.
Book Synopsis Insect-Plant Biology by : Louis M. Schoonhoven
Download or read book Insect-Plant Biology written by Louis M. Schoonhoven and published by Oxford University Press. This book was released on 2005-12 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Synopsis Grassland Farming and Land Management Systems in Mountainous Regions by : European Grassland Federation. International Symposium
Download or read book Grassland Farming and Land Management Systems in Mountainous Regions written by European Grassland Federation. International Symposium and published by . This book was released on 2011 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountainous regions, which cover nearly half of the continent’s area, are in many ways of vital importance for the European population. They supply much of the continent ́s water, are centres of biological and cultural biodiversity, provide various opportunities for recreation/ farmers. But mountainous regions are characterised by permanent natural handicaps due to topographic and climatic restrictions on economic and agricultural activity. Because of the geographical constraints to farming, work productivity is on average lower by 28% in mountain areas compared with less favoured areas, and by 40% compared with lowlands. Agriculture in mountainous regions can therefore, in general, not compete with agriculture in advantaged lowlands and, with very few exceptions, cannot hope to become competitive in adopting intensive models in response to the growing global competition.
Book Synopsis Fundamentals of Weed Science by : Robert Zimdahl
Download or read book Fundamentals of Weed Science written by Robert Zimdahl and published by Academic Press. This book was released on 2012-12-02 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.
Book Synopsis Handbook of Biological Control by : T. W. Fisher
Download or read book Handbook of Biological Control written by T. W. Fisher and published by Elsevier. This book was released on 1999-09-20 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years the use of chemical agents such as pesticides and herbicides has been effective in controlling the many varieties of pests that infest both agricultural crops and backyard gardens. However, these pests are gradually becoming resistant to these agents, because the agents themselves are acting as selective factors making the pests better and better able to resist and persist. As a result, the use of biological controlling agents is increasing. This book is a comprehensive and authoritative handbook of biological control.
Book Synopsis An Introduction to Biological Control by : A.P. Gutierrez
Download or read book An Introduction to Biological Control written by A.P. Gutierrez and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a revision of Biological Control by R. van den Bosch and P. S. Messenger, originally published by Intext Publishers. In the revision, I have attempted to keep the original theme, and to update it with current research findings and new chapters or sections on insect pathology, microbial control of weeds and plant pathogens, population dynamics, integrated pest management, and economics. The book was written as an undergraduate text, and not as a complete review of the subject area. Various more comprehen sive volumes have been written to serve as handbooks for the experts. This book is designed to provide a concise overview of the complex and valuable field of biological control and to show the relationships to the developing concepts of integrated pest management. Population regulation of pests by natural enemies is the major theme of the book, but other biological methods of pest control are also discussed. The chapter on population dynamics assumes a precalculus-level knowledge of mathematics. Author names of species are listed only once in the text, but all are listed in the Appendix. Any errors or omissions in this volume are my sole responsibility. A. P. Gutierrez Professor of Entomology Division of Biological Control University of California, Berkeley vii Acknowledgments Very special thanks must be given to my colleagues, Professors C. B. Huffaker and L. E. Caltagirone, for the very thorough review they provided and for the many positive suggestions they gave. Dr.

Book Synopsis Insects on Nettles by : B. N. K. Davis
Download or read book Insects on Nettles written by B. N. K. Davis and published by Pelagic Publishing Limited. This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stinging nettles harbour a characteristic community of insects that are widespread, abundant, and rewarding to study. This book describes the natural history of the insects in that community, and describes the way they coexist using different parts of a stinging nettle plant. It discusses the feeding habits of herbivores and predatory insects, and the parasites that feed on them, as well as the seasonal distribution of the life cycles of the different members of the community. For a nettle-dwelling insect species, a nettle patch is an island in a sea of unsuitable habitat, and this book discusses the relationship between the size and isolation of the nettle patch and the nature of its community. Keys are provided for identification, and many of the commoner species are illustrated in colour. Techniques are described for investigating insect fauna. A three page addendum draws attention to the changes in the nettle community that may be expected to result from global warming.

Book Synopsis Weed Control Economics by : Bruce Archibald Auld
Download or read book Weed Control Economics written by Bruce Archibald Auld and published by . This book was released on 1987 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE: Weeds reduce agricultural output and/or add to the costs of production and are therefore important economically. Moreover weed research scientists, administrators, and farmers make decisions about allocating resources (i.e. make economic decisions) every day. Weed control and economics are inseparable in an agricultural production context and the economic effects of weeds are diverse and complex. In this book we have endeavoured to present a broad but penetrating view of the impact of weeds and assessment of their control. The book is aimed to provide agricultural scientists, administrators, advisors, and students with a greater appreciation of the economic impact of weeds and of the economic assessment of weed control strategies and methods. For agricultural economists, the book will provide an agronomic background and an economic framework for tackling issues in weed control and research.
