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.
