The programme aims to continuously assess and monitor the mosquito population in Hungary. Monitoring invasive mosquitoes is of paramount importance because these invasive species have the potential to spread a number of pathogens that are dangerous to both humans and domestic animals, thus posing a continuing epidemiological threat. We collect data on the distribution and activity of the different species throughout the year through citizen observation reports and field trap sampling. The collected samples are continuously screened for various pathogens by genetic methods, and we create distribution maps of the results, which are then made available to everyone.
