Abstract:
Aedes caspius has a wide distribution throughout the world and can transmit Chikungunya virus, West Nile Virus (WNV), Tahyna virus and the bacterium Francisella tularensis. Sequences of the mitochondrial cytochrome C-oxidase subunit 1 (COI) and cytochrome C-oxidase subunit 2 (COII) genes have been widely used to estimate phylogenetic relationships at different taxonomic levels among this species. Adult collections were carried out by human bait, Center for Deseases Control Light Traps (CDC-LT) and aspirator during February/April, June and October/December 2013-2015 from different southern provinces of Iran and then identified morphologically with reliable keys. A total of 3,570 adult mosquitoes were collected and identified as belonging to three genera, including five species of Culex, six species of Aedes and one species of Culiseta. In this study, 1,796 specimens of Aedes caspius were identified from four provinces. Based on the COI and COII sequences obtained for Ae. caspius population, 12 and 11 haplotypes were identified, respectively. The present study evidenced a high degree of intraspecific variation among these populations of Ae. caspius.
