Book excerpt: Present water hyacinth control programs provide at best only short-term control, and thus are of short-term benefit as far as productivity of the environment is concerned, whereas successful biological control will provide long-term benefits to productivity, with a concomitant reduction in the use of chemical or mechanical disturbances of the environment. Once a biological control agent is established, it becomes an integral part of the environment and as such may properly be considered a self-renewable resource, and a beneficial addition to our environment. It is a hope that Neochetina eichhorniae will prove to be just that, and that it will, alone or in conjunction with other native or introduced natural enemies, bring about the alleviation of the problems caused by water hyacinth in the southeastern United States.

Available in PDF, EPUB and Kindle. Book excerpt: Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.

Available in PDF, EPUB and Kindle. Book excerpt: The waterhyacinth weevil 'Neochetina eichhorniae Warner' was introduced into quarantine in Puerto Rico in anticipation of future release of the insect to aid in the control of its host aquatic plant 'Eichhornia crassipes (Mart.) Solms'. The insect is being tested for host specificity by subjecting many native plant species to it; these species include many which are of particular ecological or economic significance in Puerto Rico. Although the results are preliminary, this insect species appears to be host specific to waterhyacinth as it proved to be in the continental United States. (Author).

This book was released on 1977 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1975 growing season a field experiment was begun on Lake Concordia, La., to test the potential effectiveness of selected organisms as control agents against waterhyacinths, Eichhornia crassipes (Mart.) Solms. Floating frames, each approximately 2 m square, were anchored on the lake in open water and planted with locally growing waterhyacinths. Sixty of these frames (plots) were selected for treatment with various combinations of two insects (Arzama densa Walker and Neochetina eichhorniae Warner) and two fungi (Acremonium zonatum (Sawada) Gams and Cercospora rodmanii Conway) in a random block factorial arrangement with four replications per treatment, and four frames were designated as control (no-treatment) plots. All plots were weighed at 2-week intervals throughout the growing season, flowering stalks were counted, and plant heights were measured at each weighing date. Observations were also made on insect and pathogen populations on the plots during the season. Preliminary indications are that significant reductions in the growth rate or total accumulation of waterhyacinth mass in the test plots were not achieved by any of the treatment combinations during the first season's tests, but the potential for some of the treatments to effect the desired control began to emerge during the second year.

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.

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 Book "e;Biological Control of Insects Pests"e; illustrates how to control biologically the insect's pests. It is important to know when numbers are great enough to justify artificial control and to evaluate the effectiveness of control. The text has been organized very systematically to meet the long-felt needs of increasingly large number of readers. Biological control is the use of living organisms to maintain pest populations below damaging levels. Natural enemies of arthropods fall into three major categories: predators, parasitoids, and pathogens. Predators catch and eat their prey. Some common predatory arthropods include ladybird beetles, carabid (ground) beetles, staphylinid (rove) beetles, syrphid (hover) files, lacewings, minute pirate bugs, nabid bugs, big-eyed bugs, and spiders. Biological control is the beneficial action of parasites, pathogens and predators in managing pests and their damage. Biocontrol provided by these living organisms, collectively known as natural enemies. It is especially important for reducing the number of pest insects and mites. Biological control is the beneficial action of parasites, pathogens, and predators in managing pests and their damage. Biocontrol provided by these living organisms, collectively called "e;natural enemies,"e; is especially important for reducing the numbers of pest insects and mites. Use of natural enemies for biological control of rangeland and wildland weeds is also effective. Plant pathogens, nematodes, and vertebrates also have many natural enemies, but this biological control is often harder to recognize, less well understood, and/or more difficult to manage. Conservation, augmentation, and classical biological control are tactics for harnessing natural enemies' benefits. The book will be highly useful for general entomologists, students of agricultural entomology, teachers and research scholars of zoology, especially entomology.
