Mosquito Alert
Mosquito Alert is a citizen science project that makes it easy to report tiger mosquitoes and other mosquitoes using a free app. Tiger mosquitoes are always smaller than a 1 cent coin, have a white stripe on their black dorsal shield and white stripes on their body and legs. The photos sent in are scrutinised by national and international experts and the findings are then displayed anonymously on a publicly accessible map.
Why is it important to report tiger mosquitoes?
Tiger mosquitoes are alien gnats that originally come from Asia. In recent decades, this species has spread rapidly in Europe. This species has also been found occasionally in Austria. Tiger mosquitoes are not only a nuisance, they can also transmit a variety of pathogens (e.g. the Zika virus or the dengue virus). If tiger mosquitoes spread in Austria, these diseases could also spread in our country.
Other types of gnats
In addition to tiger mosquitoes, the app can also be used to report other mosquito species. These are the Japanese bush mosquito, the Korean bush mosquito and the yellow fever mosquito, which has not yet been detected in Austria. These species are also capable of transmitting certain pathogens and could displace native species. Furthermore, findings of the native common mosquito can be reported. Of the native species, this is the one that is most important in the spread of pathogens (e.g. West Nile virus).
