Major Chikungunya and Dengue fever outbreaks occurring the last 10 years have coincided with the expansion of the mosquito vector Aedes albopictus to nearly all the continents. We characterized the ecological (larval development sites, population dynamics, insemination and daily survival rates) and genetic (diversity, gene flow, population structure) features of two Aedes albopictus populations from distinct environments (rural and urban) on Reunion Island, in the South-West Indian Ocean. Microsatellite analysis suggests population sub-structuring Ae. albopictus populations. Two genetic clusters were identified that were significantly linked to natural versus urban habitats with a mixed population in both areas. Ae. albopictus individuals prefer urban areas for mating and immature development, where hosts and containers that serve as larval development sites are readily available and support high population densities, whereas natural environments appear to serve as reservoirs for the mosquito. specialized REUNION 052 020 080 7 3 e2111 2013 1935-2735 https://www.documentation.ird.fr/hor/fdi:010060796 10.1371/journal.pntd.0002111 1935-2735 [F B010060796] https://www.documentation.ird.fr/hor/fdi:010060796 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers17-10/010060796.pdf IRD - Base Horizon / Pleins textes 2013-05-31 2018-06-09 fdi:010060796 fre
