Abstract
The invasive species Aedes (Stegomyia) albopictus (Skuse 1894) (Diptera: Culicidae) has reached several European countries, including Albania, Belgium, Bosnia and Herzegovina, Croatia, France, Greece, Israel, Italy, Montenegro, Serbia, Slovenia, Switzerland, The Netherlands, and recently Spain (Med. Vet. Entomol. 20: 150-152, 2006). Here, we present the initial characterization of the distribution of Ae. albopictus in the municipality of Sant Cugat del Vallès, Barcelona, Spain, where it was found for the first time in the Iberian Peninsula. An ovitrap sampling campaign was developed from September to December 2004 to assess the spatial distribution and abundance of Ae. albopictus to evaluate the potential of an eradication attempt. The population of Ae. albopictus in the whole area was shown to be widespread within the municipality, and it included at least another one neighboring town, so authorities were advised to develop large-scale control measures. Some indirect evidence was collected on the introduction means and date.
