Alien species of aphids in Poland

Abstract

There are around 800 species and subspecies of aphids (Hemiptera: Aphidoidea), of which nearly 40 are alien to the local fauna. The number of new species has been growing, with phytophages often transferred accidentally with plants imported to Poland. Increase in the average annual temperature contributes to the widening of the occurrence range of thermophilic species of aphids influencing their life cycle and bionomy.
