Mosquitoes are a large diverse group of insects, with members being most important as vectors of diseases. The correct identification of mosquitoes is crucial to the control of the mosquito-borne diseases. This study was designed to provide baseline data on the species composition and distribution of members of the Anophelines and Culicines genera in ten selected localities in Kosti region, White Nile State, Central Sudan. Global Positioning System (GPS) was used to select collection sites. Adult mosquitoes were collected by pyrethrum spray catch (PSC) from randomly selected houses in Allia, Alnsr, Alskahdeed, Almrabie, Alshati, Althwrat, Alraba, Block 26, Block 32 and Khadugli in Kosti region during September 2014-August 2015. The Anophelines and Culicines mosquitoes were identified using standard morphological keys. Two Anopheles species and three Culex species were morphologically identified. These were An. gambiae s.s.; An. pharoensis; Cx. quinquefasciatus; Cx. univittatus and Cx. pipiens. This is the first report of An. pharoensis in the study area. The Highest mosquito abundance was observed in the September followed by October, while the lowest mosquito abundance was in July. An. gambiae s.s and Cx. quinquefasciatus were the predominant species which has importance as they indicate the presence of Malaria and arboviral infections in the study areas; respectively. These findings are of importance in the planning and implementation of vector control strategy in the Kosti region, White Nile state.
