Abstract: Eriborus terebrans (Gravenhorst), the parasitoid of the European corn borer, Ostrinia nubilalis Hbn., was studied at four locations in central Europe during 1993-1995. Regular parasitism of O. nubilalis was found only at Blatnice in Moravia (eastern part of Czech Republic). At this location, the parasitism was 2.22% in 1993, 0.47% in 1994 and 0.06% in 1995. In 1994 and 1995, low parasitism (0.56 and 0.12% ,respectively) was found at Kráľovský Chlmec (eastern Slovakia). The records are the first from Czech Republic and Slovakia. The parasitoid was not found at Nitra (south-western Slovakia) and Wroclaw (south-western Poland). The first cocoons of E. terebrans developed in the first half of June. Parasitoid adults emerged from mid June to mid July. Results showed complete coincidence between bionomics of E. terebrans and bionomics of its host O. nubilalis.
