| Abstract
Our study aimed at providing a comprehensive list of Aphididae alien to Europe. A total of 98 species originating from other continents have established so far in Europe, to which we add 4 cosmopolitan species of uncertain origin (cryptogenic). The 102 alien species of Aphididae established in Europe belong to 12 different subfamilies, five of them contributing by more than 5 species to the alien fauna. Most alien aphids originate from temperate regions of the world. There was no significant variation in the geographic origin of the alien aphids over time. The average introduction rate was 0.5 species per year since 1800. The mean number of newly recorded species per year decreased since 2000 but this pattern may change in the following years.
