This introduction is the first to be reported in the Iberian
Peninsula and it is also the first time that an exotic mosquito
species has been detected and found to be established
in recent times in Spain. It does not seem to be associated
with the storage of used tyres or the transport of Lucky
Bamboo, the usual means of transportation of immature
stages (Knudsen, 1995; Madon et al., 2002). Other possible
means of dispersal include transportation of adult
mosquitoes in cars or lorries, although this has not been
investigated. There are two major motorways, however, in
the area of the infestation.
We consider these data to be of value to research on new
means of dispersal and to the development of strategies of
detection in threatened areas.
