Abstract

Aedes albopictus in Italy and the possible spread of this species in the Mediterranean area.

Abstract

Aedes albopictus is reported from Italy for the first time. On 14 September 1990, many of the children attending a kindergarten in Genoa were bitten by mosquitoes, especially while in the playground. An investigation confirmed the infestation, and no further mosquito bites were recorded after permethrin was sprayed both inside and outside the school on 18 September. The mosquitoes were identified as A. albopictus following the examination of an adult female. On 16 October, tyres which had been left in the playground as toys for the children were identified as potential larval habitats; no treeholes were found in oak trees (Quercus ilex) in the playground. Because of the reproductive biology of A. albopictus (Genoa lies at 44.5°N, and it is thought that A. albopictus would not mate after September and would overwinter as eggs), further surveys for A. albopictus were planned for the spring of 1991 in Genoa, and in Liguria and other areas of Italy. It is suggested that A. albopictus (which has been reported from Albania - see J. Adhami & N. Murati (1987) Revista Mjekësore, No. 1: 13-16) may be spreading in the Mediterranean region.
