Handbook for the Identification of Leafhoppers and Planthoppers of Rice


Book Description

Rice is the most important cereal grown in tropical countries and sapsucking leafhoppers and planthoppers (Homoptera: Auchenorryncha) reduce yields either by direct feeding or by transmitting virus and virus-like pathogens. Effective rice pest management requires the accurate identification of any pest species and this handbook provides keys to identify over 70 leafhopper and planthopper species recorded in the major rice growing regions. All the major pest species are included, as well as others that are frequently found but not yet considered important. A comprehensive account of all these species with descriptions, diagnoses, distributions and notes on biology is given, as well a key to nymphal stages of common Asian species and details of the separation of different instars. An introduction to the morphology and taxonomic grouping of the Auchenorryncha and four pages of colour plates are also included, and the volume is completed by a comprehensive and wide-ranging bibliography.

Leafhopper Vectors and Plant Disease Agents


Book Description

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.




Ultrastructure of the Digestive Tract


Book Description

When established four years ago, the scope of this international series in electron microscopy essentially was to provide an opportunity for the pUblication of selected review contributions by specialists in ultrastructural research. Previous volumes presented over the last three years have focused on special topics of present interest in ~'ontemporary biomedicine such as endocrine cells, reproduction, and connective tissues. In these fielCls, in fact, integrated methods of electron microscopy have contributed much to generate new ideas and concepts of general value in both basic and clinical applications. The Ultrastructure of the Digestive Tract basically follows the same guidelines and style of the other books in the series and is an invited collection of selected contributions of authors from various laboratories active in the field of electron microscopy. Therefore, although the various chapters consist of individual topics, they nevertheless should be considered as interrelated contributions of specific subjects in the field. The idea was to have critical reviews of aspects previously published elsewhere by experts in the field who, as a rule, include other relevant information in their articles in order to update and enrich the subject. This book contains fifteen chapters by renowned electron microscopists. Each chapter, according to the policy of the editors, reviews a particular topic in great detail, providing updated information, study methods and results, authors' ideas on future investigative approaches, and possible guidelines for forthcoming work. We hope that this book will be useful to cell biologists, morphologists, physiologists, and pathologists.







What Bugged the Dinosaurs?


Book Description

Millions of years ago in the Cretaceous period, the mighty Tyrannosaurus rex--with its dagger-like teeth for tearing its prey to ribbons--was undoubtedly the fiercest carnivore to roam the Earth. Yet as What Bugged the Dinosaurs? reveals, T. rex was not the only killer. George and Roberta Poinar show how insects--from biting sand flies to disease-causing parasites--dominated life on the planet and played a significant role in the life and death of the dinosaurs. The Poinars bring the age of the dinosaurs marvelously to life. Analyzing exotic insects fossilized in Cretaceous amber at three major deposits in Lebanon, Burma, and Canada, they reconstruct the complex ecology of a hostile prehistoric world inhabited by voracious swarms of insects. The Poinars draw upon tantalizing new evidence from their amazing discoveries of disease-producing vertebrate pathogens in Cretaceous blood-sucking flies, as well as intestinal worms and protozoa found in fossilized dinosaur excrement, to provide a unique view of how insects infected with malaria, leishmania, and other pathogens, together with intestinal parasites, could have devastated dinosaur populations. A scientific adventure story from the authors whose research inspired Jurassic Park, What Bugged the Dinosaurs?? offers compelling evidence of how insects directly and indirectly contributed to the dinosaurs' demise.
