First report of a stunt nematode Tylenchorhynchus zeae on corn in Gansu Province, China

Stunt nematodes (Tylenchorhynchus spp.) are important plant parasitic nematodes that feed on a wide range of economic hosts. A survey of plant parasitic nematodes was performed in corn fields in May 2019, finding corn seedlings with symptoms like yellow leaves, dwarf plants and death plants in the field (N 37°07′36″, E 102°54′08″) of Baiyin City, Gansu Province, China. The rhizosphere soil samples and roots of diseased plants were collected. Each soil sample was about 1 kg consisted of over 20

Plant-parasitic nematodes associated with sugarcane in Kilimanjaro, Tanzania

Meloidogyne, Pratylenchus, Tylenchorhynchus, Rotylenchulus, and Helicotylenchus. This study was aimed at studying the diversity of PPN associated with sugarcane, with focus on the sugarcane plantation sites of TPC Limited in Kilimanjaro region. The combination of morphological and molecular analyses revealed the presence of several genera of PPN in the soil and root samples collected from 12 different sugarcane fields. Molecular and morphological characterizations are provided for the most important PPN

The Mesostigmatid Mite Protogamasellus mica, an Effective Predator of Free-Living and Plant-Parasitic Nematodes

fact that the nematodes are quite different in size and motility and belong to different trophic groups. When sugarcane was grown in the greenhouse for 8 wk, stunt nematode (Tylenchorhynchus annulatus), a plant parasite that feeds ectoparasitically on roots, was almost eliminated from pots inoculated with the mite, and numbers of microbivores and root-lesion nematode were markedly reduced. Huge reductions in nematode populations were also observed when mites were added to microcosms containing

The Effect of Endophytic Fungi on Nematode Populations in Summer-dormant and Summer-active Tall Fescue

;cultivars, Kentucky 31 (common toxic) and Texoma MaxQ II (novel endophyte) and the Mediterranean cultivar Flecha MaxQ (novel endophyte). Endophyte-free plants of each cultivar were controls. Each cultivar 3 endophyte combination was randomly assigned to a control, low or high inoculation rate of a mixed nematode culture containing stunt nematodes (Tylenchorhynchus spp.), ring nematodes (Criconemella spp.), spiral nematodes (Helicotylenchus spp.), and lesion nematodes (Pratylenchus spp

Effects of Cover Crops on Pratylenchus penetrans and the Nematode Community in Carrot Production

production systems. Research was conducted at two field sites where cover crops were grown in Fall 2014 preceding Summer 2015 carrot production. At Site 1, rootlesion (Pratylenchus penetrans) and stunt (Tylenchorhynchus sp.) nematodes were present at low population densities (less than 25 nematodes/100 cm3 soil), but were not significantly affected (P > 0.05) by cover crops. At Site 2, P. penetrans population densities were increased (P ≤ 0.05) by ‘Defender&rsquo

Morphological and molecular characterization of Bitylenchus hispaniensis (Nematoda: Telotylenchidae) from Iran

The cosmopolitan genus Tylenchorhynchus (Cobb, 1913), is one of the biggest groups of plant-parasitic nematodes, which are migratory ectoparasites of the various plants (Siddiqi, 2000). The genus Bitylenchus (Filipjev, 1934) is very similar to the genus Tylenchorhynchus. The genus Bitylenchus is differentiated from Tylenchorhynchus in having areolated outer bands of lateral fields, a large postanal intestinal sac containing intestinal granules and fasciculi, relatively more thickened cuticle at
