Host Range Assessment of Helicotylenchus pseudorobustus (Tylenchida: Hoplolaimidae) on Pasture Species.
The host status of 15 commonly occurring pasture species for Helicotylenchus pseudorobustus was tested in a greenhouse trial. Only tall fescue, with and without Neotyphodium endophyte infection, was a good host (Pf/Pi = final/initial population > 1). Inoculation survival was tested in a second trial, which showed that only 10% of the H. pseudorobustus nematodes survived the first 7 days after i...

متن کاملSingle Modified Food Cell Induced by Helicotylenchus pseudorobustus in Corn Roots.
Helicotylenchus pseudorobustus (Steiner) Golden is a common parasite of corn (Zea mays L.) in the midwestern United States (9). A 1983 survey of northern Italy indicated that H. pseudorobustus was the most common plant-parasitic nematode associated with corn. H. pseudorobustus is generally semiendoparasitic, feeding in the cortical parenchyma of corn roots and causing necrosis and disruption of...
متن کاملCriconematina (nematoda: tylenchida) from the aleutian islands.
A new genus (Cerchnotocriconenta) and three new species (C. psephinum, Hemicycliophora amchitkaensis, and Paratylenchns amundseni) are described from Adak and Amchitka Islands in the Aleutian chain. The new genus differs from all other criconematid genera in having irregular, convex sculpturing consisting of small, oval plates on the anterior and posterior regions of each annule, with the mid-a...
