Available in PDF, EPUB and Kindle. Book excerpt: A Textbook of Plant Virus Diseases deals with a discussion of different plant viruses, their properties, and the corresponding diseases these viruses cause. It includes a list of host plants of every virus arranged alphabetically. The book discusses the new types of disease vectors, such as root-infesting fungi, nematode worms, mites, and insects that are both biting and sucking. It also discusses the development of new techniques in electron microscopy that is used to characterize in detail the causal viruses of a number of plant virus diseases. Furthermore, it presents the development of plant virus serology, as well as the improved methods of virus isolation that allow the classification of viruses into related groups. The book includes a Bibliography and an Index of Synonyms that can be used in identifying given virus name. In addition, cross-references are included for searching a particular virus under the alternative names. This book will be invaluable to ecologists, environmentalists, agriculturalists, and other scientists interested in plant viruses. Biology students will also find this reference helpful.

Download or read book Biology of the Plant Bugs Hemiptera Miridae written by Alfred George Wheeler and published by Cornell University Press. This book was released on 2001 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant bugs--Miridae, the largest family of the Heteroptera, or true bugs--are globally important pests of crops such as alfalfa, apple, cocoa, cotton, sorghum, and tea. Some also are predators of crop pests and have been used successfully in biological control. Certain omnivorous plant bugs have been considered both harmful pests and beneficial natural enemies of pests on the same crop, depending on environmental conditions or the perspective of an observer.As high-yielding varieties that lack pest resistance are planted, mirids are likely to become even more important crop pests. They also threaten crops as insecticide resistance in the family increases, and as the spread of transgenic crops alters their populations. Predatory mirids are increasingly used as biocontrol agents, especially of greenhouse pests such as thrips and whiteflies. Mirids provide abundant opportunities for research on food webs, intraguild predation, and competition.Recent worldwide activity in mirid systematics and biology testifies to increasing interest in plant bugs. The first thorough review and synthesis of biological studies of mirids in more than 60 years, Biology of the Plant Bugs will serve as the basic reference for anyone studying these insects as pests, beneficial IPM predators, or as models for ecological research.
