Abstract

Nine species in 3 families of Diptera were determined as the prey of the common yellow dung-fly Scathophaga stercoraria. Eight of these species were recorded as the prey for the first time. Preys for three species of yellow dung-flies, S. scybalaria, S. stercoraria and S. suilla, were serologically determined by the use of micro-Ouchterlony method. Positive reactions were observed against Musca domestica, M. bezzii, M. hervei and Morellia saishuensis in both male and female S. scybalaria and female S. stercoraria, and against M. domestica and M. hervei in male S. stercoraria. No positive reactions were found against these muscid flies in S. suilla. No distinct seasonal changes in the blood source were found in any species of dung-flies examined.
