Abstract: Knowing diversity and distribution of mosquitoes, vectors of numerous drastic diseases in a particular locality is as important key for development a sustainable strategy to control efficaciously these insects and the diseases they can transmit. In that context, mosquito population survey was conducted from September to November 2012 in three localities including Dang, Onaref and Sabongari III in Ngaoundere. Mosquito larvae were collected twice in a month from gutters, lakes and rivers and reared until their emergence into adults and were kept in the Eppendorf tube containing silica gel for identification. In results, a total of 1619 mosquitoes collected from the different breeding sites of Ngaoundere and 10 mosquito species grouped in 6 genera were identified. Culicinae sub-family (90.11%) was the most represented and included Culex quinquefasciatus (56.39%), Eretmapodite chrysogaster (27.67%), Aedes aegypti (0.25%), Coquilletidia maculipennis (2.66%), Culex annuliotris (0.25%), Culex pipiens (0.19%), Culex tigripes (2.10%) and Mansonia africana (0.62%). The sub-family Anophelinae (9.89%) rate was low and comprised Anopheles gambiae (8.96%) and An. funestus (0.93%). The locality of Dang was the richest in mosquito proportion (51.30%) and species (8 species). Cx. quinquefasciatus was the most abundant in the three localities. Mosquitoes were highly collected from the gutters (49.80%) and lake (10 species) was the richest in mosquito species. During the sampling period, a high mosquitoes collection was registered in October (44.20%) compared to September (29.50%) and November (26.30%). From these results, Ngaoundere is well diversified in mosquito species, especially with the presence of the malarial vectors Anopheles species and communities should mostly focused on mosquito vector control measures especially during September-November period.
