Abstract

Observations were made in Ceylon from March 1970 to February 1971 on the post-mortem incidence of Oestrus ovis L. in goats. The incidence of O. ovis was 30−2% in Jamnapari goats but 16−2% in a South Indian breed. Peaks in incidence, seen only in Jamnapari goats, and peaks in the numbers of larvae per carcase, followed the monsoons. There was a significant association between O. ovis attack and symptoms of pleuropneumonia.
