Parasitic fauna of grapes in Martuninsk District of Nagorno-Karabakh is in-vestigated. Soil samples were collected at the deepness of 10–20 and 20–40 cm. Release of nematodes from soil was carried out using standard methods. Plant roots were examined for nematodes under a binocular microscope. Identification of the genus and species was conducted using temporary and permanent glycerin drugs. Parasitic fauna of examined grapes is represented by 5 genera (Xiphinema, Lon-gidorus, Helicotylenchus, Rotylenchus, Macroposthonia). 7 species were indenti-fied: Helicotylenchus digonicus, H. dihistera, H. pseudorobustus, Macroposthonia xenoplax, Xiphinema brevicolle, X. index, X. pachtaicum. Nematodes Xiphinema – transmitters of viruses are detected in rhizosphere of damaged grape plants; these plant-parasitic nematodes are of a great economic importance because of their spe-cific pathogenic effect; besides their direct harmful effect on plant’s root system they transmit various virus infections: grapevine leafroll virus, Arabis mosaic virus etc.
