Abstract
Only the sylvatic and zoophilic population of Aedes aegypti was formerly identified in southeastern Senegal. A newly established anthropophilic population was detected in the urban area of the Kedougou city. Because of its new behavior, this species could play a primary role in the transmission of dengue and other arboviruses in this area. Because these arboviruses have no vaccine and specific treatments, vector control remains the only effective way to control their outbreaks. Effective vector control strategies require to understand some aspects of the bioecology of the vector, specially resting behavior. The aims of this study were to investigate the sites and resting behavior of Ae. aegypti in southeastern Senegal. Mosquitoes were collected in several potential resting places (rooms, tires, bricks and scrap metal) by two technicians using a CDC back-pack aspirator in the Kedougou bus station and other sites within the city and the nearby rural area. Collected mosquitoes were identified and classified. A total of 1291 mosquitoes belonging to 6 genera and 20 species were collected. Aedes aegypti was the dominant species in all the resting places investigated. This species was found resting equally in rooms, bricks, tires and ...Continue Reading
