In the English edition of his landmark book Endosymbiosis of Animals with Plant Microorganisms (1965), Professor Paul Buchner is probably the most prominent founder of systematic symbiosis research. Summarizing the most up-to-date information available on bacterial symbionts of arthropods, this text provides an overview of primary symbionts as well as the most abundant secondary symbionts known to date. To encourage the integration of theory and practice in efforts to find innovative routes to pest and disease management, the editors bring together entomologists and microbiologists to create a full picture of the complex systems. Including diagrams, tables, graphs, pictures, and chemical structures, the text offers comprehensive information and a unique perspective on a fast-growing field.
