Forty plant parasitic nematode species were identified in soil of fruit orchards in the southeastern and southwestern areas of the Danubian Lowlands and East Slovak Lowland, characterised by light sandy soil of riverine origin, locally combined with drift sand landscape. They were Ditylenchus dipsaci, Helicotylenchus canadensis, H. digonicus, H. dihystera, H. multicinctus, Rotylenchus agnetis, R. fallorobustus, R. goodeyi, Rotylenchulus borealis, Pratylenchus crenatus, P. penetrans, P. pratensis, P. thornei, Zygotylenchus guevarai, Pratylenchoides laticauda, Meloidogyne hapla, Bitylenchus dubius, Tylenchorhynchus cylindricus, Merlinius nanus, Macroposthonia antipolitana, M. rustica, M. xenoplax, Paratylenchus bukowinensis, P. elachistus, P. nanus, P. projectus, Longidorus elongatus, L. euonymus, L. juvenilis, unidentified Longidorus sp., Xiphinema diversicaudatum, X. italiae, X. pachtaicum, X. taylori, X. vuittenezi, Trichodorus primitivus, T. sparsus, T. viruliferus, Paratrichodorus macrostylus and P. pachydermus. Many of the observed species are phytopathologically important parasites of fruit trees and some are also vectors of plant viruses. The frequency of occurrence, dominance and abundance of individual species were determined.
