Leafhopper Vectors and Plant Disease Agents is the second in a multivolume series on vectors, vector-borne disease agents, and plant disease spread. This text aims to collect findings in leafhopper vector research, to suggest promising frontiers for further research, and to call attention to possible practical applications of understanding of leafhopper-pathogen-plant interactions. This book is organized into five parts. Opening chapters on the taxonomy, bionomics, and worldwide importance of leafhopper and planthopper vectors are appropriately relegated to Parts I and II. Part III focuses on vector-virus interactions of leafhopper-, planthopper-, and aphid-borne viruses and virus-induced, cytopathological changes in vectors. This part also explains the interactions of mycoplasmalike organisms (MLOs) and viruses in dually infected leafhoppers, planthoppers, and plants, as well as the transitory vector-virus interactions. The artificial and aseptic rearing of vectors, microinjection technique, vector tissue culture, and spiroplasmas and its vectors are all covered in Part IV. Part V contains chapters on specific leafhopper-borne viruses and MLOs, leafhopper and planthopper vector control, leafhopper-borne pathogens of corn-stunting diseases, Western X disease, and leafhopper-borne xylem-restricted pathogens. This text will be valuable for students, teachers, and researchers of vector-pathogen-plant relationships. Its in-depth coverage of leafhoppers and planthoppers as vectors makes this book ideally suited as a supplemental text in graduate entomology and plant pathology courses on insect transmission of plant disease agents.

This is a comprehensive up-to-date treatise including information on virus-, viroid-, and phytoplasma-induced potato diseases. The chapters of this book were written by internationally well-known experts and include novel techniques of detection, virus isolation, transmission, and epidemiology of the pathogens.

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.

The practical need to partition the world of viruses into distinguishable, universally agreed upon entities is the ultimate justification for developing a virus classification system. Since 1971, the International Committee on Taxonomy of Viruses (ICTV) operating on behalf of the world community of virologists has taken on the task of developing a single, universal taxonomic scheme for all viruses infecting animals (vertebrate, invertebrates, and protozoa), plants (higher plants and algae), fungi, bacteria, and archaea. The current report builds on the accumulated taxonomic construction of the eight previous reports dating back to 1971 and records the proceedings of the Committee since publication of the last report in 2005. Representing the work of more than 500 virologists worldwide, this report is the authoritative reference for virus organization, distinction, and structure.

In the past 15-20 years major discoveries have been concluded on potato biology and biotechnology. Important new tools have been developed in the area of molecular genetics, and our understanding of potato physiology has been revolutionized due to amenability of the potato to genetic transformation. This technology has impacted our understanding of the molecular basis of plant-pathogen interaction and has also opened new opportunities for the use of the potato in a variety of non-food biotechnological purposes. This book covers the potato world market as it expands further into the new millennium. Authors stress the overriding need for stable yields to eliminate human hunger and poverty, while considering solutions to enhance global production and distribution. It comprehensively describes genetics and genetic resources, plant growth and development, response to the environment, tuber quality, pests and diseases, biotechnology and crop management. Potato Biology is the most valuable reference available for all professionals involved in the potato industry, plant biologists and agronomists. - Offers an understanding of the social, economic and market factors that influence production and distribution - Discusses developments and useful traits in transgenic biology and genetic engineering - The first reference entirely devoted to understanding new advances in potato biology and biotechnology
