Diagnostic Manual for the Identification of Insect Pathogens by Poinar and Thomas :: 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 Berkeley, which had as its major goal the recognition and identification of insect
pathogens for practical purposes. The present work includes numerous timesaving “short cuts” which were developed after years of experience of diagnosing insect diseases.
Although emphasis is placed on identification, general background 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) definition and classification, (3) general life cycle, (4) characteristic 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 genera that infect insects are already available (Poinar, 1975, 1977).
