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

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

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

Furthermore, the PCR amplification and sequencing of the D2 to D3 expansion domains of the 28S rRNA gene, the ITS, and the mitochondrial COI were carried out. The phylogenetic relationships of P. strongyloides from Georgia to other Pelodera species and Rhabditidae were also reconstructed.

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

terminus (22.7–29.2 μm, 26.3 μm). The lateral field of J2 had three lines. Cysts (n = 10; Fig. 1C) were lemon-shaped, light to dark brown in color with protruding neck and vulval cone. 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).
