Abstract:
Anopheles culicifacies s.s and An. subpictus were the most predominant
species found in this study area and accounted for 31.2% and 41.4% respectively of
the total mosquitoes collected from the cattle - baited hut collections during the 3-
yr period. The relative adult densities of An. culicifacies s.s recorded during cooler
and rainy conditions were significantly higher than those recorded during hot
periods (p < 0.013) indicating a tendency to increase the vector density during the
cool, rainy seasons. Screening of 364 mosquitoes collected from four sampling
methods namely cattle - baited hut collection (CBHC), human baited night collections
(HBNC), larval collections (LC) and hand collections (HC) using Rp2l7 and
Rp234 DNA probes showed the absence cf sibling species A.
