When will the tiger mosquito arrive in Germany?

The tiger mosquito is originally native to the South and Southeast Asian tropics. The mosquito is an epidemiologically important vector for the transmission of many viral pathogens, including Chikungunya and dengue fever.
The first isolated specimen of this mosquito type in Germany was found in the southwestern part of the state of Baden Württemberg back in 2007. Reports of sightings have increased there since 2011, and in 2012 the insects were discovered in southern Bavaria. In every case, the mosquitoes were found in the immediate vicinity of the main long-distance transit routes from southern Europe (Italy), which leads us to presume that the insects hitched a lift with vehicles travelling north. So far, we have no reason to presume that these insects have settled in Germany on a more permanent basis, but in view of the increased occurrence of individual sightings, this is surely just a matter of time.

Dr Andreas Krüger, entomologist at the Bernhard Nocht Institute for Tropical Medicine (BNITM), answered this question.
