Abstract
Eight species of Brachycerous flies were found associated with pig manure; represented in five families viz Muscidae (Musca domestica Linnaeus, Thricops sp. Rondani), Chloropidae (Siphunculina sp. Rodani), Sphaeroceridae (Coproica ferruginata Stenhammar), Ulidiidae (Physiphora clausa Macquart) and Stratiomyidae (Hermetia illucens Linnaeus , Microchrysa flavicornis meigen, Microchrysa flaviventris Wiedemann). The most dominant family was Stratiomyidae, with three species comprising the group. Higher population of flies was recorded in the covered state than of the xposed ones with a single species difference in th total number of species realized. Fly fauna in pig manure was characterized by the occurrence of large numbers of C. ferruginata occurring the longest of time. Results suggest that fly faunal community in manure ecosystem changes over time both in terms of population and in species composition. This study also suggests that species involved in the succession do not vary from that of the species present from nearby localities with similar climatic condition and geographic orientation.
