New mosquito species, such as the Asian tiger mosquito (Aedes albopictus)—known as a vector of tropical diseases—and the Asian bush mosquito (Aedes japonicus), will continue to establish themselves in Saxony. “The models, including those for the tiger mosquito, indicate that it will become firmly established here,” entomologist Matthias Nuß told the German Press Agency. The head of the Department of Zoology at the Dresden Natural History Collections is certain that it is only a matter of time before additional sightings occur within Dresden as well as in other towns. Increasingly milder winter temperatures are further contributing to this trend.
Where do the mosquitoes find the best conditions?
So far, the new mosquito species have been found primarily in urban areas. There have been no reports of them “out in nature” so far. In densely populated areas, the insects find ideal conditions, Nuß explained.
Through an information campaign—such as a flyer published in April—the Saxon Ministry of Health and the State Research Institute for Health and Veterinary Affairs (LUA) aim to raise public awareness about the new mosquito species and the associated risks. This is because, “Only if potential breeding sites for the Asian tiger mosquito are removed—even on private property—can it be successfully contained,” said a spokeswoman. The tiger mosquito uses even the smallest pools of water as breeding grounds—such as flowerpot saucers, children’s toys, and rain barrels.
Unlike in Southern Europe—such as France—no local transmission of pathogens like the dengue or chikungunya virus by the tiger mosquito has been reported in Germany so far, according to the ministry. However, experts believe this is only a matter of time. The tiger mosquito can only transmit pathogens if it has first become infected itself by feeding on an infected host.
