“…After its first detection in Belgium in 2008 (Versteirt et al, 2012), the mosquito Aedes koreicus, commonly known as the invasive Korean bush mosquito, has invaded and established in several states in Europe and European neighbouring countries (ECDC, 2022). In some areas, such as Italy, the species is currently expanding its distribution (Gradoni et al, 2021;Negri et al, 2021;Arnoldi et al, 2022), but in others, such as Germany, it has shown a relatively low tendency to spread despite suspected repeated introductions (Hohmeister et al, 2021;Kurucz et al, 2022).…”
