چکیده

Pratylenchus arlingtoni n. sp. from the rhizosphere of grasses Poa pratensis and Festuca arundinacea at Arlington National Cemetery, VA, USA is characterised by six to eight lines in the lateral Ž eld, and pyriform to slightly overlapping pharyngeal glands.Morphological comparisons are made with lesion nematodes having similar morphometrics, six lateral lines, or crenate tail tips. Molecular sequences of the LS 28S rDNA were generated for the new species as well as P. fallax and P. convallariae. The new species differs by only 1% from identical sequences found in P. fallax and P. convallariae.

Morphometric and molecular characterization of populations of Pratylenchus kumamotoensis and P. pseudocoffeae (Nematoda, Pratylenchidae) newly recorded in Korea

At least 70 species of root-lesion nematodes, Pratylenchus spp., have been identified worldwide, many of which are serious pests of various agricultural crop plants. In Korea, only 14 species have been recorded in vegetable and fruit fields. Here, we report two new records of root-lesion nematode species in Korea based on morphometric and molecular methods. Soil samples were collected from chry...
