Studies on Malaria Vector Population Density in Three Selected Areas in Sokoto Metropolitan, Sokoto State - Nigeria

This study is conducted to determine the population density of mosquitoes in three selected area (Kofar Taramniya, Mabera and Bello Way) in Sokoto metropolis. To identified and count the population of mosquito, different breeding sites were investigated for the preferences of mosquitoes. Mosquito larvae were collected using dipper, ladle spoon from drainages, stagnant water, gutters, open wells, local pots, water tanks and cattle sheds. A total population of 4,764 mosquito larvae were collected and identified From the three (3) selected areas larvae and pupae were encounters in abundance. In Mabera area, a total of 1799 (37.7%) larvae are collected in which 1199 (45.8%) belonging to Anopheles genera and 600 (27.9%) belong to culex genera. In kofar Taramniya a total of 1649 (34.6%) larvae are collected in which 1000 (38.2%) belong to Anopheles genera and 649 (30.2%) belong to culex genera, in Bello Way, A total of 1317 (27.5%) larvae were collected, 417 (15.9%) belong to Anopheles genera and 900 (41.9%) belong to culex genera. Statistical analysis conducted indicated a significant difference (p<0.05) between the three collections. Mosquitoes encountered belong to two genera of Anopheles and Culex. The predominant genus was Anopheles with a total of 2,615 larvae while Culex has a total of 2149 larvae in all the three study areas. Considering the medical importance of mosquitoes, the information provided from this study will serve as a basis for understanding the implication of mosquitoes nuisance and provide effective control strategies against the vector and to reduce mosquitoes born disease.
