    Journal PaperJournal of Crop Protection , Volume 10 , Issue 1, 2021 October 10, {Pages 30-42 }

    Abstract

    Three populations of criconematids belonging to the subfamily Macroposthoniinae, representing three species Mesocriconema kirjanovae, M. surinamense and Criconemoides amorphous were recovered from two different geographical localities in East Azarbaijan province, northwest Iran. The recovered populations were characterized morphologically. Iranian population of M. kirjanovae is characterized by 437-542 μm long females, having 86-97 retrorse body annuli with smooth to finely crenated margin, cephalic region with two, non-retrorse annuli, 56-62 μm long stylet, the anterior lip of the vulva with two projections and conical tail with acute tip. The recovered population of M. surinamense is characterized by 495-640 μm long females, having 87-

    Abstract

    The Desmodoridae is a diverse and widespread family of free-living nematodes. Here, we provide the first record of the group in the Persian Gulf and describe three new species: Metachromadoroides sinuspersici sp. n., Zalonema iranicum sp. n. and Z. supplementorum sp. n. Metachromadoroides sinuspersici sp. n. is characterised by finely annulated cuticle, short and stout cephalic sensilla, amphidial fovea on cuticular thickening, pharyngeal bulb well developed and partitioned into three sections, absence of precloacal supplements, and presence of 6-8 pairs of rounded postcloacal papillae. Zalonema iranicum sp. n. is characterised by papilliform subcephalic sensilla (best observed with SEM), convex cephalic capsule, large multispiral amphidial

    Abstract

    This contribution provides the morphological and molecular identification of a new species of the genus Longidorella (Saevadorella). L.(S.) caspica n. sp., was recovered from the rhizospheric soil of grasses in Mazandaran province in the seashore of the Caspian Sea.

    Abstract

    This contribution provides morphological and molecular data for one new and one known species of the genus Pungentus. The first species, P. azarbaijanensis n. sp., was recovered from the rhizospheric soil of grasses, collected in West Azarbaijan province, Iran, and was characterized by 2082–2365 μm long females having an angular lip region separated from the rest of the body by a constriction, 33–35 μm long odontostyle, vulva at 43.5–51.0%, 27.0–29.5 μm long rounded-conoid tail, and males unknown.

    Journal PaperNematology , Volume 1 , Issue aop, 2020 April 9, {Pages 13-Jan }

    Abstract

    Sigmolenchus n. gen., is proposed as a new member of the Tylenchidae. The new genus is proposed based upon light and scanning electron microscopic (LM and SEM) observations and phylogenetic analyses based upon small, large and internal transcribed spacer sequences of ribosomal DNA (SSU, LSU D2-D3, ITS rDNA) and mitochondrial cytochrome c oxidase I gene (COI mtDNA) sequences. It is characterised partly by its slender body, but mainly by having a dorso-ventrally flattened, smooth and elevated cephalic region, unique elongate sinuous amphidial openings, each appearing as a wavy slit with three peaks, originating from the vicinity of the labial plate, extending posteriorly and reaching and passing the first body annulus, and a spacious amphidia

    Abstract

    Three known species of the family Criconematidae namely Criconema crotaloides, C. princeps and Ogma zernovi were recovered from natural forests in Golestan province, and were characterized based upon their morphological and morphometric characters. The Iranian population of C. crotaloides was recovered from the rhizosphere of Fraxinus excelsior and is characterized by females 517-594 μm long, having 64-70 not retrorse body annuli with smooth margin without lateral differentiation and RV= 11-14. The second species, C. princeps, was associated with Carpinus betulus and is characterized by females 421-506 μm long, having 63-69 rounded to retrorse body annuli with smooth margin, marked by distinct lateral triangular arches and RV= 11-12.

    Abstract

    Synonchium iranicum sp. n. and Richtersia bispinata sp. n. are described from the Persian Gulf and their relationships investigated using SSU phylogenetic analyses. Synonchium iranicum sp. n. is characterised by a buccal cavity with three equally sized mandibles, each with five small teeth, a rounded tail with three distinct caudal glands and distinct duct, males without gubernaculum and supplements, and short spicules. Richtersia bispinata sp. n. is characterised by multispiral amphids with 3.0-3.5 turns in males and 2.0-2.5 turns in females, cuticle with numerous, irregularly arranged, simple spines in the cervical region, 20-25 longitudinal rows of double spines in the mid-body region, 15-25 longitudinal rows of simple spines in the tail

    Abstract

    Members of the family Leptolaimidae are reported for the first time from Iran with description of two new species of Leptolaimus from the Persian Gulf in the south of the country. Leptolaimus hormozganensis sp. n. is described based upon three populations. It differs from other Leptolaimus species in the position of the pharyngeal supplement and the number of precloacal tubular supplements and has a single sickle-shaped tubular pharyngeal supplement at mid-pharynx level in both sexes, 9-12 male precloacal supplements and one female preanal supplement. Leptolaimus dimorphus sp. n. is characterised by the presence of a pharyngeal tubular supplement only in some adults, one female preanal supplement and four male precloacal supplements. It dif

    Abstract

    Sugar beet (Beta vulgaris subsp. vulgaris) is an economically important crop that provides nearly one third of the global sugar production. The beet cyst nematode (BCN), Heterodera schachtii, causes major yield losses in sugar beet and other crops worldwide. The most effective and economic approach to control this nematode is growing tolerant or resistant cultivars. To identify candidate genes involved in susceptibility and resistance, the transcriptome of sugar beet and BCN in compatible and incompatible interactions at two time points was studied using mRNA-seq. In the susceptible cultivar, most defense-related genes were induced at 4 dai while suppressed at 10 dai but in the resistant cultivar Nemakill, induction of genes involved in the

    Abstract

    Two populations of Aphelenchoides hamospiculatus n. sp. were recovered from natural forests in eastern regions of Golestan province, north Iran. Both populations were morphologically similar. The new species is described and illustrated herein. The females of the type population, recovered from soil, measured 467-550 μm long, and females of the second population, from bark, measured 545-666 μm long. It is mainly characterised by having five lines in the lateral fields, a subcylindrical tail and a single centrally located mucron at the female tail tip with fine nodules, giving it a warty appearance. It is further characterised by having a cephalic region separated from the rest of the body by a shallow constriction, stylet with small swell

    During the present study, Aphelenchoides stammeri was recovered from pine packaging wood imported from Spain to China (isolate 3334), and was also later found in China (isolate CN24). The first population (3334) was characterised by 912-1075 μm long females and 803-983 μm long males, a rounded elevated and offset lip region separated from the rest of the body by a sharp constriction having fine annuli in scanning electron microscopic (SEM) images, 14.0-19.3 μm long well-sclerotised stylet with a wide lumen (especially in the shaft) and small basal swellings, its conus forming ca 40% of the total length, the metacorpus with well-sclerotised and large central or slightly postcentral valve plates, vulva with no flap, functional rectum and a

    Abstract

    A population of Xiphinema americanum-group was recovered in association with stone fruit trees in Isfahan province, center of Iran. A reverse taxonomic approach based upon the large subunit ribosomal DNA (LSU rDNA D2-D3) and the mitochondrial cytochrome c oxidase subunit I (COI mtDNA) gene sequences in integration with morphological studies, revealed that the recovered population belongs to Xiphinema santos. The Iranian population was mainly characterized by 1240–1868 μm long females with 60–84 μm long odontostyle, a= 37.2–51.9 and c= 42.8–54.6. It is further characterized by a lip region having a depression in junction with the body, presence of visible endosymbiont bacteria in ovaries under light microscope, dorsally convex and
