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)."
