Report of diagnoses of diseased insects 1951-1961

Hilgardia, 1962, vol. 33, issue 9

Abstract: During the eleven-year period from January 1, 1951, through December 31, 1961, our diagnostic laboratory received a total of 1,257 accessions of diseased insects. (This is in addition to 575 accessions received prior to this time and already reported in a previous publication.) The diagnoses reported in the present paper are essentially brief statements as to the source of the diseased insect and the identity of the etiology involved. In order to provide a more detailed diagnosis, a new approach to diagnosis has been initiated which involves the use of more precise procedures, the use of more detailed forms for recording the results of the various examinations and tests, and a more efficient method of collating the data obtained. Accordingly, the report of past diagnostic findings is preceded by a section explaining the new methods of recording diagnostic data and of keeping diagnostic records.
