Concerning a Swedish population of Heterodera ripae Subbotin, Sturhan, Waeyenberge et Moens, 2003.

摘要

Based on morphological and morphometric characters, a Swedish population of cyst nematodes from Urtica dioica was identified as Heterodera humuli by Andersson (1979). Subbotin et al. (1997) found that cyst nematode populations on U. dioica and Humulus lupulus could also belong to a species very similar to H. humuli and until then not described. A reexamination of the population in 2006, also using molecular biology facilities now available, indicated that the nematode reported in 1979 belonged to Heterodera ripae. Heterodera humuli has not so far been found in Sweden. There are indications that the species in reports by other authors may have been Heterodera ripae rather than Heterodera humuli..
