First report, morphological and molecular characterization of Xiphinema elongatum and X. pachtaicum (Nematoda, Longidoridae) from Ethiopia
A total of six soil samples were collected around rhizosphere of citrus plants during 2010 from Melkassa Agricultural Research Center experimental station, Ethiopia. From these samples two most important ecto-plant parasitic nematodes of the genus Xiphinema were found and analysed. The genus Xiphinema is a large group of the phylum nematoda which constitutes more than 260 species. They are poly...
متن کاملAmended Descriptions of Longidorus sylphus Thorne, 1939, L. crassus Thorne, 1974, and L. fragilis Thorne, 1974 (Nematoda: Longidoridae).
Lectotypes are designated for Longidorus sylphus, L. crassus, and L. fragilis from Thorne's original specimens. Amended descriptions, tables of morphological means, ranges and standard deviations, photographs of the anterior, vulval, and tail regions, and diagnoses and relationships are provided for each of the three species to aid identification and to better determine phylogenetic relationshi...
متن کاملFirst report of Xiphinema brevicolle Lordello et Costa, 1961 (Nematoda, Longidoridae) in Japan
Mixed populations of Xiphinema americanum-group species were detected from a root zone soil sample of Japanese holly, Ilex crenata, during a survey for plant-parasitic nematodes of commercial ornamental plant nurseries in Chiba Prefecture, Japan. From the result of the morphological study, the species were identified as Xiphinema brevicolle and Xiphinema sp. This is the first record of Xiphinem...
متن کاملMorphological Observation on Longidorus crassus Thorne, 1974 (Nematoda: Longidoridae) and Its Intraspecies Variation.
Longidorus crassus is a common species and widely distributed in Arkansas. It was also identified for the first time in samples from Alabama, Iowa, Kansas, Nebraska, South Carolina, Wisconsin, and Canada. It is a parthenogenetic species, but a few males were found and were described herein for the first time. Four developmental juvenile stages were identified. A high degree of intraspecies vari...
متن کاملMolecular and Morphological Characterization of Xiphinema chambersi Population from Live Oak in Jekyll Island, Georgia, with Comments on Morphometric Variations.
A population of Xiphinema chambersi from the root zone around live oak (Quercus virginiana Mill.) trees on Jekyll Island, GA, is described using both morphological and molecular tools and compared with descriptions of type specimens. Initially, because of a few morphological differences, this nematode was thought to represent an undescribed species. However, on further examination, the morphome...
