This book was released on 2005 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically-modified corn hybrids that contain a cry gene from the bacterium Bacillus thuringiensis (Bt) are gaining popularity for controlling the corn pest, Ostrinia nubilalis. Continuous use of Bt corn, however, could select for O. nubilalis that are resistant to Bt corn. Monitoring for insect resistance is important because it could help maintain the Bt technology. A monitoring method is needed that is cost effective, not too labor intensive, and will allow sampling of large areas. A proposed method of collecting resistant insects in seed-corn drying bins, i.e., bin monitoring, could overcome these barriers. This method takes advantage of the existing system used in hybrid seed production. Seed production fields are planted in alternating strips of two rows of non-Bt corn (male) and four rows of Bt corn (female). After anthesis, male rows are destroyed. Ears of female plants are harvested and dried in bins. Some O. nubilalis larvae in the ears may move during the drying and fall underneath a partition to the bin floor, where they are collected. These larvae are brought into the laboratory and their progeny undergo a diagnostic-dose bioassay. The objectives of this study were to first find which combination of planting date and destroy date produces the least number of larvae that move from non-Bt male plants to Bt female plants; and then determine how far larvae move from downed male plants into Bt female plants. These questions are important because larvae that are captured in drying bins and escape exposure to Bt toxin (called false positives) reduce monitoring efficiency. Field studies in 2002 and 2003 were designed to simulate a hybrid seed production field. Results suggest that movement of O. nubilalis larvae from male corn are minimized when corn is planted early and male plants are destroyed by two weeks post-anthesis. This reduces the likelihood of false-positives by reducing the number of susceptible larvae moving from the non-Bt male plants to female Bt plants. Also larvae will move to all four female rows, but there were significantly more larvae found in row one than all other rows. These results can be used in developing a monitoring program to find O. nubilalis larvae with resistance to Bt corn in field populations of European corn borer.

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
