As a consequence of the climate crisis, exotic ticks or gnat species such as the Asian tiger mosquito and new pathogens such as the West Nile virus are increasingly appearing throughout Europe and thus also in Austria. For this reason, AGES has been monitoring alien gnats and new pathogens for 10 years. As the problem of the spread of alien gnat species is Europe-wide, the EU project AIM-COST was initiated with the aim of establishing a transboundary network of partners across Europe. In 2020, 22 participating countries carried out a monitoring project for the first time according to a uniform scheme. In Austria, this study was organized by AGES in cooperation with the University of Veterinary Medicine Vienna and carried out with the help of several project partners (Biological Station Illmitz, Gelsenbekaempfung Leithaauen, Inatura, Landesmuseum Klagenfurt, Museum Joanneum (Graz), University of Innsbruck, University of Salzburg, Verein Biologische Gelsenregulierung March-Thaya-Auen). Within the framework of this monitoring, the occurrence and distribution of alien species of catfish are recorded using ovitraps ("egg traps") according to uniform European standards. For the first time, an overview of the distribution of the Japanese bush mosquito in the country could be generated. The Asian tiger mosquito has meanwhile been detected in Tyrol, Lower Austria, Styria and Vienna. 10th International Conference of the European Mosquito Control Association Abstracts of the event
