Morphometrics of Xiphinema rivesi Dalmasso, 1969 (Nematoda: Dorylaimida) from Slovenia.
X. americanum nematodes were found in soil samples collected near the roots of peach trees from an orchard at Bilje near Nova Gorica, Slovenia, during the spring of 2002. Re-sampling in different locations in the same area confirmed their presence in high numbers (from 5 up to 100 nematodes/100 ml soil). Adult females and juveniles were isolated and identified morphologically using molecular taxonomy methods as Xiphinema rivesi. In addition, morphometrical variability of X. rivesi, isolated from different host plants was examined.
