Dipteran Fauna Of An Abattoir And Its Contiguous Fallow Plot In A Guinea savanna Ecosystem

Abstract

The pitfall trap was used in the study of the dipteran populations of an abattoir and a contiguous fallow plot, in relation to their relative abundance and distribution. A total number of 140 adult species of Synydas and Stomorhina cribrata, and 400 dipteran larvae were captured at the abattoirusing pitall techniques, with correspondingly fewer species of similar dipterans trapped at the contiguous fallow plot. Significant difference existed in the trapping of the Diptera larvae with more trapped at the abattoir than the fallow plot using Student t-test. There was also a preponderance of calliphorid species at the abattoir when the sweep net was used, with these species implicated as being potential pests of medcal and forensic importance. The presence of Sarcophaga sp. and Fannia canicularis in the sweep net collection at the abattoir was also traced tothe presence of decaying fall-offs from carcass. Other possible implications of the collected dipteran species at the abattoir and its vicinity were also discussed.
