Available in PDF, EPUB and Kindle. Book excerpt: The Theory and Practice of Biological Control covers conventional biological control achievement in the major crop types and in public health problems. Composed of five sections encompassing 28 chapters, this book discusses the basic information concerning developments in other biologically based alternatives to chemical pesticides. The first two sections discuss the philosophy, theory, scope, history, and the biological and ecological bases of biological control. These sections also deal with the impact of predators and the host relationships of parasitoids and pathogens. The following section presents the methodological aspects of biological control. Discussions on the variability of natural enemies as encountered in biological control work; the fitness of individuals and populations; the ways fitness is being or can be influenced by importation procedures; and the ability of imported natural enemies to adapt to the new environment are included. The fourth section outlines the accomplishments of conventional biological control in various types of crops, forests, and public health areas. Lastly, the various components of integrated pest control other than conventional biological control that forms the essential ways used in the integrated control approach are covered in the last section of the book. This book is an ideal source for plant pathologists and researchers, microbiologists, parasitologists, and public health professionals.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The explosive increase in the world's human population, with conse quent need to feed an ever-increasing number of hungry mouths, and the largely resultant disturbances and pollution of the environment in which man must live and produce the things he needs, are forcing him to search for means of solving the first problem without intensifying the latter. Food production requires adequate assurance against the ravages of insects. In the last three decades short-sighted, unilateral and almost exclusive employment of synthesized chemicals for insect pest control has posed an enormous and as yet unfathomed contribution to the degradation of our environment, while our insect pest problems seem greater than ever. Properly viewed, pest control is basically a question of applied ecology, yet its practice has long been conducted with little regard to real necessity for control, and in some cases, with little regard to various detrimental side-effects or long-term advantage with respect, even, to the specific crop itself. This book deals fundamentally with these questions. The development of pesticide resistance in many of the target species, against which the pesticides are directed, has occasioned an ever-increasing load of applications and complexes of different kinds of highly toxic materials. This has been made even more "necessary" as the destruction of natural enemies has resulted, as a side effect, in the rise to pest status of many species that were formerly innocuous. The application of broad-spec trum pesticides thus has many serious and self-defeating features.

Download or read book Integrating Biological Control into Conservation Practice written by Roy van Driesche and published by John Wiley & Sons. This book was released on 2016-05-17 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species have a critical and growing effect upon natural areas. They can modify, degrade, or destroy wildland ecosystem structure and function, and reduce native biodiversity. Landscape-level solutions are needed to address these problems. Conservation biologists seek to limit such damage and restore ecosystems using a variety of approaches. One such approach is biological control: the deliberate importation and establishment of specialized natural enemies, which can address invasive species problems and which should be considered as a possible component of restoration. Biological control can be an effective tool against many invasive insects and plants but it has rarely been successfully employed against other groups. Safety is of paramount concern and requires that the natural enemies used be specialized and that targeted pests be drivers of ecological degradation. While modern approaches allow species to be selected with a high level of security, some risks do remain. However, as in all species introductions, these should be viewed in the context of the risk of failing to reduce the impact of the invasive species. This unique book identifies the balance among these factors to show how biological control can be integrated into ecosystem restoration as practiced by conservation biologists. Jointly developed by conservation biologists and biological control scientists, it contains chapters on matching tools to management goals; tools in action; measuring and evaluating ecological outcomes of biological control introductions; managing conflict over biological control; and includes case studies as well as an ethical framework for integrating biological control and conservation practice. Integrating Biological Control into Conservation Practice is suitable for graduate courses in invasive species management and biological control, as well as for research scientists in government and non-profit conservation organizations.
