Book Description
Bacillus thuringiensis (Bt) has been used as a biopesticide in agriculture, forestry and mosquito control because of its advantages of specific toxicity against target insects, lack of polluting residues and safety to non-target organisms. The insecticidal properties of this bacterium are due to insecticidal proteins produced during sporulation. Despite these ecological benefits, the use of Bt biopesticides has lagged behind the synthetic chemicals. Genetic improvement of Bt natural strains, in particular Bt recombination, offers a promising means of improving efficacy and cost-effectiveness of Bt-based bioinsecticide products to develop new biotechnological applications. On the other hand, the different Bacillus species have important biotechnological applications; one of them is carried out by producing secondary metabolites, which are the study object of natural product chemistry. The amazing structural variability of these compounds has attracted the curiosity of chemists and the biological activities possessed by natural products have inspired the pharmaceutical industry to search for lead structures in microbial extracts. Screening of microbial extracts reveals the large structural diversity of natural compounds with broad biological activities, such as antimicrobial, antiviral, immunosuppressive, and antitumor activities that enable the bacterium to survive in its natural environment. These findings widen the target range of Bacillus spp., in special B. thuringiensis, besides insecticidal activity and help people to better understand its role in soil ecosystem.

Book Description
This volume presents a comprehensive perspective of the biopesticides Bacillus thuringiensis and Lysinibacillus sphaericus, from their basic biology to agriculture, forestry and public-health applications. It covers their ecology, virulence factors, and genetic characterization. The topics related to agriculture and forestry include mode of action, receptors of insect pests, and heterologous expression of toxins in insect cells and plants. Public-health researchers will find information on vector control programs with an emphasis on the Neotropical region. The book also discusses new products and the global market.

Book Description
This book describes new strategies being used to combat disease agents and invertebrate pests. Outstanding experts from the United States, Belgium, China, Guatemala, Japan, Philippines, Singapore, and Thailand have contributed chapters that cover the latest achievements in genetic engineering, emphasizing the microbial and viral biological control agents that can provide environmentally safe, economical control systems. Topics discussed include genetic engineering of Bacillus thuringiensis and B. sphaericus, the development of insect resistance to microbial biocontrol agents, engineering of baculoviruses and nematodes, bioengineering of plants, plant transformation by particle bombardment, fusion of cultured insect cells, new immunodiagnostic assays and control measures against parasitic human diseases, and genetically engineered microbial agents for malaria control. The book also presents improved mass production procedures of microbial and viral biocontrol agents, as well as regulatory and environmental aspects of genetically engineered biocontrol agents. Biotechnology for Biological Control of Pests and Vectors will provide a valuable reference for researchers and students of biological control, microbiology, virology, and molecular biology.

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.

Book Description
Reviews recent research in eukaryotic, agricultural, environmental, and microbial biotechnology with a view to keeping scientists, government officials, and industrialists up to date on trends and advances in subspecialties adjacent to their own. Some of the specific topics are moveable elements in the human genome, agricultural applications of coat protein mediated protection, and the analysis of epitope in the cholera family of enterotoxins. The 29 papers were presented at a conference in Bangkok, Thailand, August 1990. Annotation copyright by Book News, Inc., Portland, OR

Book Description
Make the right decisions when it comes to pest control in agriculture! Bacillus thuringiensis: A Cornerstone of Modern Agriculture explores the impact that one of the most prominent biologically based pesticides has had on pest control technology—and the issues that surround its use. The book examines the development, use, and management of technologies derived from Bacillus thuringiensis (Bt), addressing the health, economic, environmental, and social concerns generated by the deployment of genetically engineered crops. Authors representing a diverse cross section of the international scientific community contribute review articles and research findings that address the use of Bt in microbial formulations and transgenic crops, technological advances in the genetic engineering of plants, advances in methodologies, and improved agricultural practices and productivity through the use of Bt cotton. Bacillus thuringiensis: A Cornerstone of Modern Agriculture examines the vital issues surrounding this Gram-positive bacterium. Contributors from academia, government, and industry address the safety of Bt for human consumption, its effects on non-target organisms, the role of microbial Bt products in crop production in the United States, and the utility and management of transgenic plants. The book also explores: engineering Bt transgenic rice for insect pest protection the Bt potato in developing countries Bt expression in sugarcane and cauliflower a comparative analysis of Bt cotton in Argentina the ecological impact, gene expression, and current resistance management requirements of Bt cotton in the United States and much more! Bacillus thuringiensis: A Cornerstone of Modern Agriculture is an essential resource for advanced students and technical specialists working in agriculture, biotechnology, entomology, pest management, and crop sciences. Stakeholders will also find it invaluable in regulatory decision making about genetically engineered crops, pesticide use, and crop protection.
