The western region of Bahia undergoes accelerated agricultural development, which has generated infrastructure problems as the lack of sanitation and waste collection. Thus these problems play an important role in increasing the supply of breeding places of mosquitoes. Considering the possibilities of contacts between the vector and human population, the objective of this work was to study the adult Culicidae fauna in an urban area of western Bahia and to verify species of public health concern. The captures of adults were performed in Municipality of Barreiras during the period of February 2009 to January 2010, from 5:30 p.m. to 9 p.m. A total of 1,744 adults mosquitoes were capture and eight genera were identified: Aedes, Coquilletidia, Culex, Limatus, Mansonia, Ochlerotatus, Psorophora and Uranotaenia. The predominant species belong to Culex quinquefasciatus. Others species found with potential epidemiological importance were Aedes aegypti and Ochlerotatus scapularis. Whereas many species collected in Barreiras have epidemiological importance and occur even during the dry season due to lack of sanitation, it is important that municipalities of western Bahia be kept under constant epidemiological surveillance.
