This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
Download or read book Genetically Modified Pest Protected Plants written by National Research Council and published by National Academies Press. This book was released on 2000-08-23 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the risks and benefits of crops that are genetically modified for pest resistance, the urgency of establishing an appropriate regulatory framework for these products, and the importance of public understanding of the issues. The committee critically reviews federal policies toward transgenic products, the 1986 coordinated framework among the key federal agencies in the field, and rules proposed by the Environmental Protection Agency for regulation of plant pesticides. This book provides detailed analyses of: Mechanisms and results of genetic engineering compared to conventional breeding for pest resistance. Review of scientific issues associated with transgenic pest-protected plants, such as allergenicity, impact on nontarget plants, evolution of the pest species, and other concerns. Overview of regulatory framework and its use of scientific information with suggestions for improvements.

Download or read book Insect Resistance Management for Bt Corn written by Jennifer L. Price and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of Bt corn's efficacy in controlling European corn borer, farmers are required to implement an insect resistance management (IRM) program that constrains each farmer to plant no more than 80% of the farm's corn to Bt varieties. This refuge must be planted within a half-mile of Bt corn and must be contained on the same farm. Community refuge schemes, those which allow the refuge area to be planted on a neighboring farm, have been proposed. In this analysis, we estimate the potential gains to all farms in the community in two representative locations: Pennsylvania and Iowa. The results of a decision analysis model show that the potential gains are very small; the greatest is only $652 over a 2000-acre community ($0.33 per acre). This gain would almost certainly be offset by the costs of developing such a community.

This book was released on 1999 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition, planting Bt corn early in northern Iowa provided more economic benefits. Drought stress may affect the activity of the Bt protein in leaf tissue during reproductive stages of growth; lower mortality of 3rd instar 0. nubilalis was observed. Decreased efficacy from drought stress will affect management of certain Bt corn events. Larvae receiving a sublethal dose of Bt will have resistance management implications.

Download or read book Dispersal Behavior of Neonate European Corn Borer Ostrinia Nubilalis on Transgenic Bt Corn written by Jessica Ann Goldstein and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Most Lepidoptera disperse as adults, but in some groups the larvae disperse as well. Larval dispersal takes the form of ballooning; larvae use silk to hang off of plant surfaces and some get picked up by the wind. The longer the silk length, the greater the drag and the more likely the larva is to get picked up by the wind and the farther the larva will travel. The European corn borer (ECB), Ostrinia nubilalis, has been observed ballooning and is currently the target of a large control effort using transgenic Bt corn. I examined the differences between ECB larval dispersal on Pioneer 34K78 Mon 810 event Bt corn and Pioneer 34K77 non-Bt isoline corn. I tested plant abandonment, larval dispersal in artificial plots and ECB silking behavior. My results suggest that ECB larvae that hatch on a Bt corn plant abandon that plant with a higher frequency than ECB larvae that hatch on a non Bt corn plant and that ECB larvae are capable of reaching neighboring corn plants by ballooning. This dispersal behavior may play a significant role in resistance management, particularly in the spacing of non-Bt refuges. These experiments help us to better understand ECB neonate behavior and may apply to other insects under Bt selection pressure.

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
