[Extension of the area of Aedes albopictus in Italy. 1st report of the species in central Italy].

A new infestation by Aedes albopictus was discovered in Civitavecchia, Central Italy, in October 1992. This follows previous records of the species in North Italy, where the first infestation was observed in 1990 in the city of Genoa. The present finding clearly indicates the capacity of Aedes albopictus to spread all over Italy and to become a permanent pest in Southern Europe. In spite of the expected embryonic diapause in October, larval breeding was observed in a fifteen-liter glass jar with a narrow neck, left outdoor.
