Pratylenchus thornei Sher & Allen, 1953

The migratory endo-parasitic root-lesion nematode Pratylenchus thornei is parasitizing on a wide range of host plants, including economic important once as wheat, corn, barley, roses and fruit trees like apple. It is a cosmopolitan species and also common in the Netherlands.

This species is relatively easy recognisable, as it belongs to the longest ‘Pratylenchids’ with a high lip region, empty spermatheca (males are very rare) and a typical trucated tail tip. The not offset lip region is composed of three (transverse) annuli, while the cephalic framework is strongly sclerotized.
