Study on population dynamics of black flies imagos

Abstract

A study was conducted on three dates in three different months and four micro-niches at Assop falls to identify the species of Black flies, ascertain the relative abundance/distribution of black flies in various micro niches based on reproductive pattern, to ascertain if environmental and anthropological factors associated with ponds/rivers is important for accurate predictions at the generic levels. There was a P0.05) based on sexual dimorphism at various points was established. The results when compared to previous studies carried out in same vicinity about three decades ago indicated that the distribution and abundance of black flies in Assop falls were influenced by environmental changes and by human activities.
