investigation on the occurrence of aedes species in borderline of iran and azerbaijan for control of arboviral diseases

Background: to investigate the diversity of the genus aedes present in the natural areas of ardabil province, north-west of iran. methods: this cross-sectional study was carried out from apr to oct 2016 in north-western of iran. thirty-three areas of 10 cities which are border areas were selected randomly. the larvae were collected 2 times in each month during the seasonal activities of mosquitoes and the larvae were identified morphologically according to the appropriate identification keys. results: overall, 694 larvae were collected from four counties, from which only 7.2% were aedes larvae. three species of aedes were identified which include ae. caspius, ae. vexans and ae. flavescens. aedes flavescens is reported from ardabil province for the first time. conclusion: aedes species were a high density in borderline of iran and azerbaijan. therefore, the north parts of ardabil province are a suitable habitat for aedes species mosquitoes. care should be taken for vector control in the case of occurrence of any arboviruses transmitted by aedes mosquitoes.
