fauna and larval habitats of mosquitoes (diptera: culicidae) of west azerbaijan province, northwestern iran.

b a ckground: several important diseases are transmitted by mosquitoes. despite of the potential of the occurrence of some mosquito-borne diseases such as west nile, dirofilariasis and malaria in the region, there is no recent study of mosquitoes in west azerbaijan province. the aim of this investigation was to study the fauna, composition and dis- tribution of mosquitoes and the characteristics of their larval habitats in this province. m e t hods: larvae and adult collections were carried out from different habitats using the standard methods in twenty five localities of seven counties across west azerbaijan province. results: overall, 1569 mosquitoes including 1336 larvae and 233 adults were collected from 25 localities. the de- tails of geographical properties were recorded. five genera along with 12 species were collected and identified in- cluding: anopheles claviger , an. maculipennis s.l . , an. superpictus , culex pipiens , cx. theileri , cx. modestus , cx. hortensis , cx. mimeticus , culiseta longiareolata , ochlerotatus caspius s.l . , oc. geniculatus    and uranotaenia unguiculata . this is the first record of oc. geniculatus in the province. conclusion: due to the geographical location of the west azerbaijan province, it comprises different climatic con- dition which provides suitable environment for the establishment of various species of mosquitoes. the solidarity geographical, cultural and territorial exchanges complicate the situation of the province and its vectors as a threat for future and probable epidemics of mosquito-borne diseases.
