Morphological and molecular characterisation of Pratylenchus arlingtoni n. sp., P. convallariae and P. fallax (Nematoda: Pratylenchidae)
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 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 se...
متن کاملMorphometric 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...
متن کاملMorphological and molecular characterization of Pratylenchus lentis n. sp. (Nematoda: Pratylenchidae) from Sicily.
Pratylenchus lentis n. sp. parasitizing roots of lentil in Sicily, Italy, is described and illustrated. The new species is characterized by a relatively high lip region with three annuli, mean stylet length of 16 mum, with anteriorly flattened knobs, cylindrical body with a relatively anterior vulva, large and ovoid spermatheca full of sperm, plump tail with truncate, irregularly annulated term...
متن کاملInteractions between Heterodera avenae and Pratylenchus neglectus on Wheat.
In a long-term field experiment, differential population densities of Heterodera avenae were produced by frequent cropping with resistant (cv. Panema) or susceptible (cv. Peniarth) oat. The two oat cultivars were equally good hosts of Pratylenchus neglectus in a glass house experiment with field soil. On wheat crops grown after oats in field experiments, P. neglectus population densities in roo...
متن کاملEffect of Field Crops on Population Densities of Pratylenchus neglectus and P. thornei in Southeastern Australia; Part 1: P. neglectus.
Eighty-one cultivars from 12 field crop species were assessed for suitability as hosts to the root lesion nematode, Pratylenchus neglectus, in two field trials. Host status was assessed on the basis of either final P. neglectus densities in soil or multiplication rate under different crops. Both techniques gave consistent results for crop and cultivar ranking, and it was therefore concluded tha...
