Juveniles. The scatter plot diagram based on
functional and replacement odontostyle and
body length reveal the presence of four
juveniles stages (Figure 1A, 3)
Xiphinema pachtaicum was found in
rhizosphere of Vitis vinifera L. (Bîrlad, Urlai,
Nazarcea, Obrejia), and Prunus avium L.
(Ostrov) (Table 1, 2, 3).
All populations of X. pachtaicum studied are
similar in most morphological and
morphometrical characters. However, Obrejita
517
specimens compared to other have shorter
odontostyle (ave.78.6 vs ave. 90-82.4 μm).
This species is wide-spread in Europe and has
been shown to occur in several countries such
as: Bulgaria (Choleva, 1975, Lamberti et al.,
1983, Peneva & Choleva 1992), Croatia
(Samota et al. 1994), Czech Republic (Kumari,
2004, Kumari et al. 2005), Macedonia,
Montenegro, Serbia (Barsi & Lamberti, 2002).
Slovakia (Liskova, 1992, Lamberti et al.,
1999), Hungary (Repasi et al., 2008), Spain,
Italy (Gutiérrez-Gutiérrez et al., 2011).
