Abstract: A survey of mosquitoes population and breeding sites was conducted in Gadau campus of Bauchi state university, Nigeria. Dipping method was used for the sampling using a dipper or pipette based on container types. All the breeding sites or sources of mosquito larvae were grouped into four different container types: Reservoir A, natural container B, drainage C, & plastic containers D. A total of 188 mosquitoes were identified belonging to two genera (Culex and Anopheles spp) using dipping method. From the result site A had a total abundance of 48 (25.53%), site B had 68 (36.17%), site C had 43(22.87%) and site D had 29 (15.43%). Anopheles had a total abundance of 41 (21.81%) and Culex had a total abundance of 147 (78.19%). Out of the 188 mosquitoes sampled, 170 of the mosquitoes were separated into male Culex (51) and female Culex (78), male Anopheles (13) and female Anopheles (28) and female using the identification keys. The Shannon Index diversity of the mosquitoes was H 1.21 and the evenness was E 0.87, and the richness of the Anopheles spp. (0.49) mosquitoes was found to be lower than that of Culex spp (0.72). There is a significant difference between Anopheles and Culex mosquito species sampled in the four sites at (p<0.05). The abundance and richness of the mosquitoes was high due to the higher mosquitoes sampled, hence the risk of transmitting diseases was very high.
