Citizen science data on the presence of invasive mosquitoes in Hungary

Climate change, intensified tourism and trade activity result in several exotic mosquito species invading the temperate zone, which has considerable ecological and economic consequences and threatens human health due to the pathogen-transmitting role of these organisms. Accordingly, three invasive mosquito species (Aedes albopictus, Ae. japonicus, and Ae. koreicus) have been described in the last decade in Hungary, a Central European country. It is crucial to understand how invasive species are introduced and their distribution is expanded at the country-level, for which intense surveillance programs are needed.
We have established a citizen science program, in which we asked the public to submit reports on their observations of invasive mosquitoes. During a three-year campaign, we have collected and taxonomically validated about 3,000 reports that can be arranged along both the temporal and spatial scales. We aggregated these observations into 35 km2 quadrats and examined if these can..., Citizen science dataset on the presence of invasive mosquito species spreading in Hungary (2019–2021).
