BOOK EXCERPT:
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.

BOOK EXCERPT:
Plant Diseases and Vectors: Ecology and Epidemiology is the fourth in a five-volume series of books on vectors of plant disease agents. It is comprised of 10 chapters representing the expertise of 13 outstanding scientists from a total of seven different countries. This book begins with a discussion on the ecological involvement of wild plants in plant virus pathosystems. This is followed by the principles and applications of enzyme-linked immunosorbent assay (ELISA) in diagnosing plant viruses and monitoring their movement in the environment. The next two chapters detail the epidemiologies of diseases caused by leafhopper-borne viruses, mollicutes, and rickettsia-like organisms. This book also covers the developments in understanding the importance of helper agents to the transmission ecologies of many aphid-borne plant viruses. It also encompasses the factors that can contribute to the epidemiology and control of a disease affecting a major agricultural crop of the world. A vector of plant viruses not covered in earlier volumes of the series (the host plant, itself) and the man-made epidemiological hazards in major crops of developing countries are also described. This volume will broaden the knowledge of transmission ecology and disease epidemiology, not only by serving as a valuable supplemental textbook, reference work, and bibliographical source, but also by catalyzing novel syntheses of thinking and stimulating further research in the area.

BOOK EXCERPT:
Only 14 years have passed since the first publication appeared which implicated mycoplasmas as agents of plant disease. The diseases them selves have been known for much longer; indeed clover phyllody, a typical example, was described in the seventeenth century, well before any animal mycoplasma diseases had been documented. The early history of plant mycoplasmas is described in Chapter 2 and one obvious conclusion to be drawn from the frustrating experiences of the earlier workers is that the experimental methods at their disposal were simply inadequate for the task. Progress in science depends critically upon the development of new methods. Although important advances have been made in plant and insect mycoplasmology, notably in the discovery of spiroplasmas, many intractable problems remain. Most plant myco plasmas cannot yet be cultured in vitro, and their natural plant habitat, the phloem, is one of the most difficult plant tissues for the experi menter to handle, placing severe restrictions on the type of experiments which can be performed in vivo. It is clear that radically new methods may be required to solve these problems. A survey of the progress which has been made shows that application of techniques from a wide range of disciplines has been necessary. A successful individual or group of workers must possess the skills of a plant pathologist, a plantsman, a plant physiologist, a light-and electron microscopist, a bacteriologist, a biochemist, an immunologist, an ento mologist, a virologist and a molecular geneticist.

BOOK EXCERPT:
Volume Two of the new guide to the study of biodiversity in insects Volume Two of Insect Biodiversity: Science and Society presents an entirely new, companion volume of a comprehensive resource for the most current research on the influence insects have on humankind and on our endangered environment. With contributions from leading researchers and scholars on the topic, the text explores relevant topics including biodiversity in different habitats and regions, taxonomic groups, and perspectives. Volume Two offers coverage of insect biodiversity in regional settings, such as the Arctic and Asia, and in particular habitats including crops, caves, and islands. The authors also include information on historical, cultural, technical, and climatic perspectives of insect biodiversity. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and examine the consequences that an increased loss of insect species will have on the world. This important text: Offers the most up-to-date information on the important topic of insect biodiversity Explores vital topics such as the impact on insect biodiversity through habitat loss and degradation and climate change With its companion Volume I, presents current information on the biodiversity of all insect orders Contains reviews of insect biodiversity in culture and art, in the fossil record, and in agricultural systems Includes scientific approaches and methods for the study of insect biodiversity The book offers scientists, academics, professionals, and students a guide for a better understanding of the biology and ecology of insects, highlighting the need to sustainably manage ecosystems in an ever-changing global environment.

Mycoplasma are the smallest free-living prokaryotes lacking a cell wall and are, therefore, highly pleomorphic. This book is a contribution toward an understanding of the complex problems of tree diseases caused by mycoplasma-like organisms and their relatives.
