Update of Re-evaluation of Bacillus Thuringiensis


Book Description

Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act and Regulations, has completed a re-evaluation of Bacillus thuringiensis and has concluded that continuing registration for this active ingredient and associated end-uses is acceptable, provided that certain mitigation measures are adopted. Additional data requirements are identified. Summaries of the data and information reviewed during the re-evaluation and the proposed regulatory decisions were published in the Proposed Acceptability for Continuing Registration document PACR2006-09, Re-evaluation of Bacillus thuringiensis, dated 16 November 2006, and the decision statement (RVD2008-18), which was published on 6 May 2008. Following the decision statement publication, some mitigation measures such as label statements have been revised. The revised labelling statements describing the acceptable uses and conditions of use for Bacillus thuringiensis end-use products are summarized in Appendix I.--Document.




Microbial Megaplasmids


Book Description

Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside. Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.




Use of Microbes for Control and Eradication of Invasive Arthropods


Book Description

This is a diverse presentation about the use of arthropod-specific pathogens for control and eradication of invasive arthropod species. Basic concepts supporting use of pathogens for microbial control are covered as well as societal and environmental concerns.

Bacillus Thuringiensis


Book Description

Provides a definitive source of information on the environmental, non-target and human safety aspects of using the bacterium Bacillus thuringiensis (B.t.) as a biological control agent. B.t. is used worldwide as an effective agent for controlling many species of insect pest, either by crop spraying or genetic engineering of crop plants. Recently questions have been raised due to health concerns over inhalation of the bacterial spores, and fears of gene-swapping. This reference provides a well-balanced comprehensive discussion on the subject.







Insect Resistance Management


Book Description

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




Integration of Insect-Resistant Genetically Modified Crops within IPM Programs


Book Description

Insect pests remain one of the main constraints to food and fiber production worldwide despite farmers deploying a range of techniques to protect their crops. Modern pest control is guided by the principles of integrated pest management (IPM) with pest resistant germplasm being an important part of the foundation. Since 1996, when the first genetically modified (GM) insect-resistant maize variety was commercialized in the USA, the area planted to insect-resistant GM varieties has grown dramatically, representing the fastest adoption rate of any agricultural technology in human history. The goal of our book is to provide an overview on the role insect-resistant GM plants play in different crop systems worldwide. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production.
