First record of Aphidius ericaphidis (Hymenoptera, Braconidae) in Europe: North American hitchhiker or overlooked Holarctic citizen?

Abstract

Aphidius ericaphidis, an aphid parasitoid originally described from North America, is recorded in Europe for the first time, based on morphological and molecular analyses. The species is recorded in Serbia, the Netherlands, Sweden and the United Kingdom. It was formerly recorded as Aphidius sp./Ericaphis latifrons/Vaccinium uliginosum from the Alps (France). The possible origin of A. ericaphidis, as well as its likely distribution, is discussed in relation to its host. As it is a specific parasitoid of Ericaphis aphids, especially the invasive aphid Ericaphis scammelli on blueberries, its potential as a biocontrol agent is also discussed.
