Ecological factors associated to the invasion by alien Aedes species in the province of Trento, northern Italy

Aedes albopictus, Ae. koreicus and Ae. japonicus are of increasing public health concerns in Europe. In Trentino province (northern Italy), an established population of Aedes albopictus is reported since late 90’ (1) whilst Ae. koreicus was detected for the first time in 2013 (2). The most recently introduced IMS in our province is Ae. japonicus, recorded in 2022 (Arnoldi D., personal communication). To get an insight into the ecological process affetting IMS abilty to establish into new areas and to obtain a number of parametrs of utility to develop risk maps and predictive mathematical models, we carried out a series of investigation combining filed observation and laboratory experiments. Here we summarise some of the results so far obtained.
