Globodera artemisiae (Eroshenko et Kazachenko, 1972) was found in Poland in autumn of 2004. The nematodes developed on Artemisia vulgaris L. Morphological and morphometric characteristics of the Polish population correspond to earlier known populations from Far East of Russia, Armenia, China, Germany and Sweden. The traditional identification was confirmed by molecular methods. On the basic of rDNA sequences of G. artemisiae, deposited in GenBank the product of expected size was obtained. Subsequently, the results were confirmed by sequencing analysis.
Ditylenchus destructor is a serious pest of numerous economically important plants worldwide. The population of this nematode species was isolated from the root zone of Ammophila arenaria on a Baltic Sea sand dune. This population’s morphological and morphometrical characteristics corresponded to D. destructor data provided so far, except for the stylet knobs’ height (2.1–2.9 vs 1.3–1.8) and their arrangement (laterally vs slightly posteriorly sloping), the length of a hyaline part on the tail end (0.8–1.8 vs 1–2.9), the pharyngeal gland arrangement in relation to the intestine (dorsal or ventral vs dorsal, ventral or lateral) and the appearance of vulval lips (smooth vs annulated). Ribosomal DNA sequence analysis confirmed the identity of D. destructor from a coastal dune.
