Abstract
An update of the mosquito fauna of 15 settlement areas in Kaduna metropolis within the
Northern Guinea Savannah zone of Nigeria was made from November 2004 - November
2005. Larval samples were obtained and 15 species of mosquitoes identified comprising
of the following; Aedes aegypti L, 138 (1.97%), Ae. vittatus Bigot,103 (1.47%), Ae.
simpsoni Theobald, 12 (0.17%), Anopheles species, 4 (0.06%); Culex pipiens molestus
Forskal, 3307 (47.30%), Cx. pipiens quinquefasciatus Say, 1836 (26.26%), Cx. pipiens
pipiens, 456(6.52%), Cx. decens Theobald, 868 (12.42%), Cx. tigripes Grandpre,31
(0.44%), Cx. univittatus Theobald, 34 (0.49%), Cx. horridus Edwards, 115 (1.64%), Cx.
musarum Edwards, 40 (0.57%), Cx. nebulosus Theobald, 4(0.06%), Cx. macfei
Edwards,41(0.59%), Cx. duttoni, 2 (0.03%). The most abundant species encountered in
all the 15 settlements sampled were Culex. p. molestus and Cx. p. quinquefasciatus.
Mosquito species bred in eight different sites identified as major breeding habitats in
Kaduna metropolis; the proportion of total catch from these habitats is indicated:
Concrete gutters (38.23%), Stagnant pool/pond (29.92%), Peridomestic runoffs (PDRF)
(22.3.4%), Clay pot (0.86%), Metal containers (0.59%), Abandoned tyres (2.73%),
Plastic containers (1.22%) and Roadside potholes (3.61%). Significant difference in
breeding populations was noticed among habitats (P=0.024). Concrete gutters, Stagnant
pool/ponds and PDRF were encountered in all settlement areas. There was no significant
difference in the total mosquito species sampled among the 15 settlements (P=0.436).
The old settlement areas had more mosquito species;(13) in comparism to 11 species in
the new settlement areas. Diversity in the mosquito species breeding observed during the
wet months was significantly higher than those of the dry months (P=0.004); with the
highest species diversity of 11 species in August. There was a preponderance of Culex
breeding habitats for Culicine
mosquitoes, particularly Culex. p. molestus and Cx. p. quinquefasciatuspipiens complex (Cx. p molestus and Cx. p quinquefasciatus) over other mosquito species
and this suggests that environmental degradation by human activities associated with
rapid urbanization, has provided numerous insanitary
