Aedes albopictus Skuse (Diptera:Culicidae) is a mosquito species of major importance involved in the transmission of several diseases (Dengue, Yellow Fever, Chikungunya, West Nile Fever). Ae. Albopictus is considered as the most efficient vector of Chikungunya virus and second for the dengue. This species has a high dispersal ability and is considered as an invasive species. Following the Chikungunya outbreak in 2006 at La Réunion island, the biology of Aedes albopictus is under investigation. The dispersal of male Ae aAlbopictus must be understood in a SIT programme in order to optimize the release of sterilized males using landscape ecology tools.
