English. In 2008, a lucerne aphid parasitoid Aphidius ervi Haliday was first recorded in Slovenia. This oligophagous parasitoid is used as biological control agent against bigger aphid species. By sampling aphid mummies on different locations in Slovenia in 2008, we found parasitoid Aphidius ervi on nine host plants (corn, pea, alfalfa, red clover, winter wheat, oat, onion, potato and winter barley). Among 1812 primary parasitoids found in Slovenia in 2008, there were 46 individuals of Aphidius ervi; 21 male and 25 female parasitoids. In the present paper description of the species, its geographic distribution and host plant-aphid-parasitoid associations are given.

Ta oligofagni parazitoid se uporablja kot biotični agens večjih vrst listnih uši. Parazitoida Aphidius ervi smo v letu 2008 našli na 9 gostiteljskih rastlinah (koruza, grah, lucerna, črna detelja, ozimna pšenica, oves, čebula, krompir in ozimni ječmen) v Sloveniji, in sicer med vzorčenjem ušjih mumij. V letu 2008 smo nabrali 1812 primarnih parazitoidov, med njimi je bilo 46 osebkov vrste Aphidius ervi; 21 je bilo samcev in 25 samic. V prispevku je opisana vrsta, njena geografska razširjenost in povezava med gostiteljsko rastlino, ušjo ter parazitoidom.
