Book excerpt: Western Corn Rootworm, Diabrotica virgifera virgifera LeConte, has been a major economic pest of maize in the Americas for many years. However, since the early 1990's it has become an increasing threat to crops in Europe and is expected to spread to all maize growing areas of the continent. This book provides a comprehensive review of current knowledge of the biology and ecology of this insect pest and how it might be managed in order to limit its damage as it spreads into new agroecological areas. Cultural, biotechnical, and biological control measures are addressed, as are ecological baseline data such as population dynamics, economic thresholds and aspects of its behaviour. The book also examines the potential of plant protection techniques currently used in North America to be applied in Europe.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of the effect of alternate host plants on rootworm population dynamics is critical to the formulation of effective IRM programs. Three studies were conducted to evaluate the effects of alternate host plant phenology on the survivorship, growth, development, and host searching behavior of larvae, as well as the effect of initial feeding of larvae on an alternate host followed by movement to rootworm resistant transgenic corn on beetle emergence and reproductive fitness of emerged female beetles. Initial feeding on alternate hosts followed by movement to Bt maize increased beetle emergence from Bt maize, fecundity of those that survived, and the number of viable eggs produced. In greenhouse trials, western corn rootworm larvae had significantly greater survival on younger grassy weeds (4 to 6 weeks old) versus older grassy weeds. In behavioral tests, western corn rootworm larvae recognized younger roots (4 week old) as hosts but did not recognize older roots (7 or 10 week old) as hosts. Phenological changes in grassy weeds could encourage movement of larvae from weeds to transgenic maize.

Download or read book Insect Resistance Management written by David W. Onstad and published by Academic Press. This book was released on 2013-10-08 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. - Provides insights from the history of insect resistance management (IRM) to the latest science - Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues - Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research - Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The western corn rootworm (WCR - Diabrotica virgifera virgifera Coleoptera: Chrysomelidae) is an important maize pest worldwide and the most damaging part of the beetle's life cycle is the below ground feeding of the larvae on the maize roots. The larvae use CO2 to locate maize roots. This orientation cue can be incorporated into the chemical control of the larvae by attracting them to a soil insecticide (Tefluthrin) with CO2 emitting capsules, implementing an "Attract & Kill" (A&K) strategy. This mechanism is eventually aiming at enhancing insecticide activity and reducing the application ...

Download or read book Arthropod Management and Landscape Considerations in Large Scale Agroecosystems written by Michael J. Brewer and published by CABI. This book was released on 2024-08-16 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: For large-scale agroecosystems, patterns of pest population increases (graded increases or abrupt outbreaks) and declines (graded suppression or abrupt crashes) vary considerably and are influenced by factors within crop fields and across broader landscape scales. Better understanding of pest population dynamics and the implications of spatial interactions on the function and development of pest management approaches are the main themes of this important book. The book builds from a 60+ year history of field-based pest management by focusing on the drivers of pest management in large-scale agroecosystems and the landscape-scale processes that affect these drivers and contribute to variation in pest outbreaks and suppression. These drivers include abiotic and biotic influences such as weather, spatial composition and arrangement of landscape elements, and widely applied managed inputs such as planting and crop rotation schedules, crop varietal selection, and land and soil conservation efforts. The book introduces general concepts, opportunities, and challenges of arthropod management in large-scale agroecosystems. The book is essential reading for researchers in applied entomology and ecology and for pest management practitioners.
