Knowledge of mosquito vectors fauna is crucial to disease control measures. Entomological surveys were conducted in endemic areas of malaria and lymphatic filariasis at Ed Damazin locality, Blue Nile State, to investigate mosquito species composition. Mosquitoes were caught throughout the year, in dry and wet seasons during July 2007–August 2008. Mosquitoes were collected as larvae using WHO standard dipping method and as adults by CDC miniature light traps, a local made light traps (Madeni light trap; MLT 2008) and pyrethrum spray collections. A total number of 1953 collected adult mosquitoes; 191 using light traps and 1762 using pyrethrum spray collections, while 599 larvae specimens were collected. Nine species were recorded in the area namely; An. arabiensis, An. squamosus, An. pharoensis, An. rufipes, An. funestus, Cx. quinquefasicatus, Cx. univitatus, Cx. anntenatus and Cx. sitiens and the apparent density was compared.
