ABSTRACT. The first occurrence of the invasive mosquito species Aedes koreicus outside the endemic area was reported in Belgium in 2008. In subsequent years, this species was recorded in several countries of central Europe. In Russia, Ae. koreicus was first recorded in 2013, but data on its distribution remain scanty. The aim of this study was to determine the current range and habitat preferences of Ae. koreicus in Krasnodar Krai and Crimea. The study is based on the materials collected in 2019–2022. The distribution of Ae. koreicus is located in the zone of humid subtropical climate. In Krasnodar Krai, the dispersal of Ae. koreicus occurred within coastal-marine terraced landscapes with humid broad-leaved forests. In Crimea, the mosquitoes dispersed in mountain meadows and steppes of summit plateaus and southern coastal sparse forests, which are characterized by Mediterranean climate. All sites where the presence of Ae. koreicus is confirmed in Crimea are located along a major federal highway, which allows us to assume that the spread of Ae. koreicus could have occurred passively by ground vehicles. The altitudinal distribution of Ae. koreicus ranges from 60 to 1025 m a.s.l.
KEY WORDS: mosquitoes, climate zones, habitat specificity.
