Distribution and history of Russian wheat aphid, Diuraphis noxia (Kurdj.) in the Carpathian basin (Hom., Aphididae)

Abstract

The Carpathian Basin has been classified as one of the model areas of Russian wheat aphid (=RWA), Diuraphis noxia (Kurdj.), expansion from the southeast to Central Europe. Explorations in 2002 as well as the summarized information published earlier centered the evidence for RWA in the northern and northeastern parts of the area and its occurrence was detected and verified in the area up to the sub-mountains of the Carpathian Mountain Range. The history and distribution peculiarities of RWA in the Carpathian Basin and area are reviewed and discussed.
