After the publication of the Diagnostic Manual for the Identification of Insect Pathogens, the authors received many queries asking why they had not included the larger metazoan parasites as well as the microbial forms. An examination of the literature indicated that pictorial guides to the identification of nematodes and the immature stages of insect parasites were unavailable. Consequently we decided to rewrite the sections cover ing insect pathogens and combine these with new sections on ento mogenous nematodes and the immature stages of insect parasites. The result is the present laboratory guide, which is unique in covering all types of biotic agents which are found inside insects and cause them injury or disease. Included as parasites are insects and nematodes. Among the pathogens included are viruses, rickettsias, bacteria, fungi, and protozoans. Emphasis is placed on identification with an attempt to use the most easily recognizable characters. Use of a certain number of technical terms is unavoidable, and explanations of these can be found in most biological dictionaries or the glossary of invertebrate pathology prepared by Steinhaus and Martignoni (1970).

This manual was prepared for the diagnosis of insect diseases caused by infectious agents. The agents (or pathogens) included here are fungi, protozoans, bacteria, viruses, and rickettsias. The present work was prepared after much deliberation and discussion with students and teachers who felt a guide of this type would be valuable for diagnosing the microbial diseases of insects. It was modeled after a seminar given on the same subject at Berke ley, which had as its major goal the recognition and identification of insect pathogens for practical purposes. The present work in cludes numerous timesaving "short cuts" which were developed after years of experience of diagnosing insect diseases. Although emphasis is placed on identification, general back ground information on the various pathogens is also included. Thus, under each of the five groups of pathogens, the following topics are discussed: (1) various types of associations with insects, (2) defini tion and classification, (3) general life cycle, (4) characteristics of diseased insects, (5) factors affecting natural infections, (6) methods of examination, (7) isolation and cultivation, (8) important taxonomic characters, (9) tests for infectivity, (10) storage, (11) an illustrated key to the genera (or group in the case of viruses), and (12) literature, especially that pertaining to identification. Although often included with insect pathogens, entomogenous nematodes are not covered here since illustrated keys to those gen era that infect insects are already available (Poinar, 1975, 1977).

Insect Pathology is designed for a broad spectrum of readers. Is should be useful to students, lecturers, and researchers requiring information about the principles in insect pathology and the biology of pathogens. It should serve as a resource for specialists to learn about other insect pathogen systems, for generalists to become aware of advances in insect pathology, and for scientists and students, beginning or otherwise, interested in learning about insect pathology. This book was originally intended to update the 1949 test by E. A. Steinhaus entitled Principles of Insect Pathology. The purpose for this book was twofold: To serve (1) as a text for an insect pathology and/or biological control class and (2) as a comprehensive reference source. Because this book summarizes much of the available information, its usefulness as a textbook for an insect pathology class is apparent. Although the literature citations are extensive, they are far from complete. The literature in insect pathology is voluminous and for the past decade has been expanding at an almost exponential rate. A complete review of the literature is beyond the scope of the book, and an omission of a reference does not preclude its importance. Our citations, however, should serve as a good starting point for those who wish to obtain further information. We have attempted to cover equally all subdisciplines, but shortcomings are unavoidable. For these, we take full responsibility.

Biological Techniques is a series of volumes aimed at introducing to a wide audience the latest advances in methodology. The pitfalls and problems of new techniques are given due consideration, as are those small but vital details not always explicit in the methods sections of journal papers. In recent years, most biological laboratories have been invaded by computers and a wealth of new DNA technology and this will be reflected in many of the titles appearing in the series. The books will be of value to advances researches and graduate students seeking to learn and apply new techniques, and will be useful to teachers of advanced undergraduate courses involving practical or project work. This manual describes the broad array of techniques that are used in insect pathology. It will provide biologists, insect pathologists, entomologists, and those interested in biological control, with the necessary information to work on a variety of pathogen groups. This book will be an essential laboratory reference for insect pathologists. Features include: * Step by-step instructions on how to isolate, identify, culture, bioassay and store the major groups of entomopathogens * Details of the practical knowledge needed by beginners to apply the techniques * Chapters written by an international group of experts * Discussion of safety testing of entomopathogens in mammals and also broader methods such as microscopy and molecular techniques * Provides extensive supplemental literature and recipes for media, fixatives and stains

Both volumes of Parasites and Pathogens of Insects provide in-depth coverage of the interface between insect parasites and pathogens and hosts, and explore the relationships between these partners. They emphasize biochemical and molecular interactions, basic biology, and the roles of hormones, receptors, and other cellular components in modulating interactions between host insects and attacking agents. These topics also are assessed in relation to biotechnology and biological control. In the short term, these volumes fill a void in current literature by emphasizing basic interactions at the biochemical and molecular levels. In the long term, these interactions may provide avenues for exploitation to enhance the rate of "beneficial" parasitism or to reduce the rates of disease transmission and infection of vertebrate hosts. Key Features * Presents the latest information on insect parasites and pathogens * Describes biochemical and molecular host-parasite and host-pathogen relationships * Covers mechanisms of insect pathogenicity and resistance * Provides exceptional breadth of coverage and authoritative reviews * Special topics * Transposable elements in insect pathogens * Co-evolution and gene transfer between hosts and invaders * Biological control

Novel Aspects of Insect-Plant Interactions Edited by Pedro Barbosa and Deborah K. Letourneau Focusing on three trophic levels, this study widens the current understanding of the ecological interactions between plants, herbivores, and their parasitoids and predators. Emphasized are the mediating effects of plant-derived allelochemicals on those interactions. The book also covers microorganisms as mediators of intertrophic and intratrophic interactions; theory and mechanisms: plant effects via allelochemicals on the third trophic level; and key roles of plant allelochemicals in survival strategies of herbivores. 1988 (0 471-83276-6) 362 pp. Plant-Animal Interactions Evolutionary Ecology in Tropical and Temperate Regions Edited by Peter W. Price, Thomas M. Lewinsohn, G. Wilson Fernandes and Woodruff W. Benson An outgrowth of an international symposium on Evolutionary Ecology of Tropical Herbivores held at UNICAMP, Brazil, this unique collaborative effort from leading scientists worldwide is the first comparative analysis of the existing ecological systems of temperate and tropical regions. In-depth and timely, the book's manifold analyses includes a discussion of tropical and temperate comparisons; mutualistic relationships between plants and animals; antagonistic relationships between plants and animals; plant-butterfly interactions; specificity in plant utilization; and community patterns in natural and agricultural systems. Amply illustrated with 150 detailed graphics, the book provides a fascinating visual tour of the flora and fauna described. 1991 (0 471-50937-X) 639 pp. Integrated Pest Management Systems and Cotton Production Edited by Raymond E. Frisbie, Kamal M. El-Zik and L. Ted Wilson This work sheds light on the link between the thriving U.S. cotton crop and integrated pest management. It offers a unique theoretical and conceptual framework for studying the cotton-IPM system. Other relevant issues such as the development and use of pest models, quantitative sampling principles in cotton IPM, economic injury levels and thresholds for cotton pests, and strategies and tactics for managing weeds, plant pathogens, nematodes, and insects are also described. Covering every facet of IPM technology, this is a significant contribution to the literature of pest management. 1989 (0 471-81782-1) 437 pp.

Insect Pathology: An Advanced Treatise, Volume 2 reviews the significant progress that has been made in insect pathology, as well as the major research trends in the field. This book is concerned with bacterial, fungus, protozoan, and parasitic diseases, along with the epizootiology of infectious diseases, diagnosis, methodology, and microbial control. Organized into 17 chapters, this volume begins with a brief consideration of the taxonomy of entomogenous bacteria, including common problems of bacterial taxonomy as a whole. The book then discusses diseases caused by certain spore-forming bacteria, such as clostridial pathogens and pathogens of the genus Bacillus. The text also explains milky diseases and their development within the insect host; nonsporulating bacterial pathogens that cause diseases in insects; and infections caused by Coelomomyces and Entomophthorales. The book also introduces the reader to insect diseases caused by hyphomycetous Fungi Imperfecti (Deuteromycetes) not usually associated in nature with a perfect stage, diseases associated with Cordyceps, and infections attributed to parasites belonging to the group Sporozoa. This book is essential reading for entomologists.

This handbook gives a comprehensive and copious illustrated description, with original art work, of the most common diseases in laboratory reared insect colonies, comprising Viruses (Baculoviridae, Reoviridae, Poxviridae, Iridoviridae); Bacteria (Bacillaceae, Pseudomonadaceae, Enterobacteriaceae); Rickettsia; Fungi and Microsporidia and Protozoa. Gregarine and Coccidian parasitoids are also depicted. Manuals for the diagnostic of insect diseases have been published in the 90’s, however, these were intended for professional insect pathologists or for proficient training in invertebrate pathology, hence requiring some scientific background in insect pathology. Currently, most guides are web based, not comprehensive and solely addressing the most common diseases in a particular insect, or group of insects, reared in laboratory facilities. A comprehensive and proficient practical handbook for students and technicians working with insect reared colonies is lacking in the current literature.

Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.
