The Asian tiger mosquito again in Sardinia

Aedes (Stegomyia) albopictus (Skuse, 1894) (Diptera Culicidae), the Asian tiger mosquito, was detected in Cagliari, in the South of Sardinia, in 1994-95, but the prompt intervention of the local public health agency achieved the eradication of the introduced population. In autumn 2006, the Asian tiger mosquito has been detected again on the island. It is present in two important port cities, Cagliari in the South and Olbia in the North-East. In the latter location, Ae. albopictus seems to have reached a high population density in contrast to the south of the region where the climactic conditions are not so favourable for this species.
