This study was conducted to assess the Awba reservoir insects’ communities and the health status
through the determination of insects’ abundance, composition, distribution and water qualities parameters.
Water samples and insects were collected bi-weekly from August through December, 2009. Insects were
sampled using standard entomological methods, while water samples was analyzed using standard Winkler’s
titrimetric and APHA methods to determine the chemical properties. Water analyses and insects’ identifications
were conducted in the laboratory in Department of Zoology, University of Ibadan, Oyo State. The results show
that only DO and phosphate-phosphorus had significant difference (p<0.05). A total of 1,154 insects were
recorded, Chironomidae and Culicidae were most abundance. The chemical properties and the distinct taxa
found in the water suggest that the water body is polluted and may be dangerous to the health of people around
the reservoir.
