Molecular 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 morphometrics of the nematodes from live oak tend to agree with most of the morphometrics in the

First Report of Carrot Cyst Nematode Heterodera carotae in Mexico: Morphological, Molecular Characterization, and Host Range Study

During 2008 to 2016 in several nematological surveys in the Tepeaca Valley, Puebla, Mexico, carrot cyst nematode, Heterodera carotae was found parasitizing carrots, Daucus carota. The nematode was present in 61% of the sampled fields with high population densities, causing severe carrot yield losses in the Tepeaca Valley. The aim of this work was to study morphology, morphometrics, host range, and molecular characterization of the nematode. The morphological and morphometric characterization

Morphological and Molecular Identification of Longidorus euonymus and Helicotylenchus multicinctus from the Rhizosphere of Grapevine and Banana in Greece

Plant-parasitic nematodes such as Longidorus euonymus and Helicotylenchus multicintctus are species widely distributed in central Europe as well as in Mediterranean area. In Greece, both species have been previously reported but no morphometrics or molecular data were available for these species. Nematode surveys in the rhizosphere of grapevines in Athens carried out in 2016 and 2017, yielded a Longidorus species identified as Longidorus euonymus. Similarly, a population of Helicotylenchus

overlapping morphometrics of some species groups in the genus Xiphinema make quarantine regulations and protection methods more difficult. Therefore, accurate identification of Xiphinema species using integrate approach is strongly recommended to create a basis for plant pest management. In Vietnam, eight species of the genus Xiphinema have been reported, however, molecular identification are not available for most of them (Nguyen and Nguyen, 2000), and thus, a higher diversity of Xiphinema spp. is

Abstract Pseudacrobeles (Pseudacrobeles) curvatus sp. n. was collected from potato fields in Gyeongsangnam-do, South Korea. The new species shares morphological characters typical of the genus Pseudacrobeles, including three lateral incisures that fade posteriorly near the phasmid openings. The new species differs from other Pseudacrobeles species by its smaller body size and a comparatively shorter corpus relative to the isthmus length. In this study, we provide a comparison of morphometrics

glycerol for three to five days. Specimens were then mounted on permanent glass slides to allow handling and observation under LM. Measurements of specimens were taken with an Olympus BX51 (Olympus, Tokyo, Japan) ocular micrometer. Morphometrics included de Man’s indices and standard measurements. Spicule terminology used follows Peña-Santiago et al. (2014). Some of the best-preserved specimens were photographed with the same microscope equipped with differential interference contrast and a Canon EOS

Rotylenchus wimbii n. sp. (Nematoda: Hoplolaimidae) associated with finger millet in Kenya

Kenya. The potential importance of this nematode as a pest of finger millet was evidenced by its dense population in the soil sample and its presence observed in the finger millet root system (revealed by the fuchsin staining method). Nematode characterization was carried out based on morphological information obtained from light microscopy (LM) and scanning electron microscopy (SEM) studies. Illustrations, morphometrics, and molecular information of ITS, 18S, and 28S of rDNA and COI of mtDNA are

Morphological and molecular characterization of Pratylenchus species from Yam (Dioscorea spp.) in West Africa

Nematodes from 27 samples fixed in formalin were processed to anhydrous glycerin following the glycerin-ethanol method (Seinhorst, 1959) as modified by De Grisse (1969). Permanent slides were prepared and used to record morphometrics and morphological features (Castillo and Vovlas, 2007; Inserra et al., 2007) using an Olympus BX51 DIC microscope equipped with a Nikon digital camera. Additional morphological and morphometrical data were recorded from temporary slides made from DESS fixed specimens

The cysts had ambifenestrated vulval cone and no bullae was present. Morphometrics included body length excluding neck (370.5–714.4 μm, 555.7 μm); body width (165.6–411.1 μm, 310.9 μm); neck length (36.5–66.3 μm, 49.8 μm); fenestra length (26.3–42.5 μm, 35.8 μm), and fenestra width (19.1–31.5 μm, 23.8 μm).
