First report of Xiphinema rivesi in Slovenia

Xiphinema rivesi (EPPO A2 quarantine pest) is a member of the X. americanum group, and is able to transmit at least four North American nepoviruses (Cherry rasp leaf, Tobacco ringspot, Tomato ringspot and Peach rosette mosaic nepoviruses). So far, its presence had been reported in Europe only from a few limited sites in France, Germany, Portugal and Spain. In spring 2002, X. rivesi was detected in soil samples taken near roots of peach trees, in an orchard at Bilje, near Nova Gorica, Slovenia. Resampling in June and September on the same site and its immediate vicinity confirmed the presence of the nematode in relatively high numbers (5 per 100 mL of soil). The identity of the nematode was confirmed by the Dutch NPPO in Wageningen. The origin of this infestation is unknown. As the nematode was found near the river Vipava, in an area of extensive stone and pome fruit production, it is thought that X. rivesi might also be present in other orchards in this region. This is the first report of X. rivesi in Slovenia.
The situation of Xiphinema rivesi in Slovenia can be described as follows: Present, found in a limited area near Nova Gorica.
