Table 1 Specifics of the reviewed studies, including monitoring trigger, scope and methods used. A “dynamically adjusted” area is given if monitoring efforts were expanded while the field work was conducted. In the column “Year of first detection”, if the presence of Ae. j. japonicus in the monitored country was already reported, the corresponding study is referenced

From: The Asian bush mosquito Aedes japonicus japonicus (Diptera: Culicidae) in Europe, 17 years after its first detection, with a focus on monitoring methods
