Vectors of Plant Pathogens is a collection of papers that discusses the interrelationship of plant pathogens with their vectors. This collection deals with the numerous vector groups associated with plant pathogens. One paper describes the biology, feeding behavior and distribution of aphids, leafhoppers, plant hoppers, mealy bugs, whiteflies, psyllids, membracids. Another paper addresses the virus transmission characteristics of the mealy bugs during preliminary fasting or feeding, acquisition access time, post-acquisition fasting or feeding, and the inoculation access time. Other papers also discuss the involvement of insects in transmitting bacterial and fungal pathogens; the authors list unresolved issues such as the role of insects in overwintering of bacterial pathogens or the association of the fungus with a particular vector. One author describes some suspected fungi transmission such as the pea stem necrosis virus, red clover necrotic mosaic virus, and the tomato bushy stunt virus. Another paper examines the fate of plant viruses in mite vectors and convectors particularly the viruses found in wheat, barley, or brome grass. Agriculturists, botanists, and researchers in the field of botany, conservation, and plant genealogy will find this book useful.

Authored by experts in the field, this updated edition covers techniques and approaches, viruses, TSEs, bacteria, parasites, vectors, and broader health issues seen in production systems, including metabolic diseases. The book will be an essential reference for professionals in the field, scientists and researchers, students, breeders, veterinarians, agricultural advisors and policy makers.
Authored by an integrated committee of plant and animal scientists, this review of newer molecular genetic techniques and traditional research methods is presented as a compilation of high-reward opportunities for agricultural research. Directed to the Agricultural Research Service and the agricultural research community at large, the volume discusses biosciences research in genetic engineering, animal science, plant science, and plant diseases and insect pests. An optimal climate for productive research is discussed.
The use of drugs in food animal production has resulted in benefits throughout the food industry; however, their use has also raised public health safety concerns. The Use of Drugs in Food Animals provides an overview of why and how drugs are used in the major food-producing animal industriesâ€"poultry, dairy, beef, swine, and aquaculture. The volume discusses the prevalence of human pathogens in foods of animal origin. It also addresses the transfer of resistance in animal microbes to human pathogens and the resulting risk of human disease. The committee offers analysis and insight into these areas: Monitoring of drug residues. The book provides a brief overview of how the FDA and USDA monitor drug residues in foods of animal origin and describes quality assurance programs initiated by the poultry, dairy, beef, and swine industries. Antibiotic resistance. The committee reports what is known about this controversial problem and its potential effect on human health. The volume also looks at how drug use may be minimized with new approaches in genetics, nutrition, and animal management.
Phytoplasma-associated diseases are a major limiting factor in the context of the quality and productivity of many ornamental, horticultural and other economically important agricultural crops worldwide. Annual losses due to phytoplasma diseases vary, but under pathogen-favorable conditions they have disastrous consequences for the farming community. As there is no effective cure for these diseases, the management options focus on their exclusion, minimizing their spread by insect vectors and propagation materials and on the development of host plant resistance. This book discusses the latest information on the epidemiology and management of phytoplasma-associated diseases, providing a comprehensive, up-to-date overview of distribution, occurrence and identification of the phytoplasmas, recent diagnostics approaches, transmission, losses and geographical distribution as well as management aspects.
Biology of Disease Vectors presents a comprehensive and advanced discussion of disease vectors and what the future may hold for their control. This edition examines the control of disease vectors through topics such as general biological requirements of vectors, epidemiology, physiology and molecular biology, genetics, principles of control and insecticide resistance. Methods of maintaining vectors in the laboratory are also described in detail.No other single volume includes both basic information on vectors, as well as chapters on cutting-edge topics, authored by the leading experts in the field. The first edition of Biology of Disease Vectors was a landmark text, and this edition promises to have even more impact as a reference for current thought and techniques in vector biology.Current - each chapter represents the present state of knowledge in the subject areaAuthoritative - authors include leading researchers in the fieldComplete - provides both independent investigator and the student with a single reference volume which adopts an explicitly evolutionary viewpoint throuoghout all chapters. Useful - conceptual frameworks for all subject areas include crucial information needed for application to difficult problems of controlling vector-borne diseases
Parasiticide Discovery: In Vitro and In Vivo Tests with Relevant Parasite Rearing and Host Infection/Infestation Methods, Volume One presents valuable screening methods that have led to the discovery of the majority of parasiticides commercialized in the animal health industry. As much of the knowledge of parasiticide discovery methods is being lost in the animal health industry as seasoned parasitologists retire, this book serves to preserve valuable methods that have led to the discovery of the majority of parasiticides commercialized in animal health, also giving insights into the in vitro and in vivo methods used to identify the parasiticide activity of compounds. - Addresses current issues of resistance, along with combination uses for resistant parasites - Presents useful, authoritative information (chemical, pharmaceutical, clinical, etc.) for the pyrantel family of compounds - Includes a discussion on screening methods in combination therapies - Provides cutting-edge material for an evolving area of scientific discussion - Includes in vitro and in vivo screens and parasite maintenance and culture methods
The World Livestock 2013: Changing disease landscapes looks at the evidence of changing disease dynamics involving livestock and explores three key areas: the Pressure, including drivers and risk factors that contribute to disease emergence, spread and persistence; the State, describing the disease dynamics that result from the Pressure and their subsequent impact; and the Response, required both to adapt and improve the State and to mitigate the Pressure. The report argues that a comprehensive approach for the promotion of global health is needed to face the complexities of the changing disease landscapes, giving greater emphasis on agro-ecological resilience, protection of biodiversity and efficient use of natural resources to ensure safer food supply chains, particularly in areas worst afflicted by poverty and animal diseases. Speeding up response times by early detection and reaction – including improved policies that address disease drivers – is key. Forging a safer, healthier world requires engagement in the One Health approach, which involves all relevant actors and disciplines spanning animal, human and environmental health sectors.
The confirmed case of "mad cow" disease (BSE) in June 2005 illustrates the economic impact of disease outbreaks, as additional countries closed their markets to U.S. beef and beef products. Emerging diseases also threaten public health-11 out of 12 of the major global disease outbreaks over the last decade were from zoonotic agents (that spread from animals to humans). Animal Health at the Crossroads: Preventing, Detecting, and Diagnosing Animal Diseases finds that, in general, the U.S. animal health framework has been slow to take advantage of state-of-the-art technologies being used now to protect public health; better diagnostic tests for identifying all animal diseases should be made a priority. The report also recommends that the nation establish a high-level, authoritative, and accountable coordinating mechanism to engage and enhance partnerships among local, state, and federal agencies, and the private sector.
