Download or read book Vectors of Plant Pathogens written by Kerry F. Harris and published by Academic Press. This book was released on 2013-10-02 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
