There are as yet no known cases in Europe of vector-spread diseases from a tiger mosquito. However, although at this moment they may not be harmful, there is cause for concern. The tiger mosquito can be a vector for a whole litany of major diseases including dengue and yellow fever and West Nile. Aedes albopictus began to spread out from its Asian homeland in the 1970s, above all thanks to the sea transport of tyres. Moreover, the parent species Aedes aegypti, present as a result of previous ship-borne invasions, was the vector which caused severe outbreaks of dengue and yellow fever several centuries ago throughout the Mediterranean, though it was later eradicated. Both Aedes albopictus and Aedes aegypti share a similar habitat type and bionomics and bear the same vector diseases.
