biostudies-literatureUnknown58(3)Nguyen TDSeveral species of the sheat nematodes, <i>Hemicycliophora</i> spp., have been known to cause significant damage to agricultural crops, including <i>Hemicycliophora arenaria</i>, <i>H. conida</i>, <i>H. parvana</i>, <i>H. poranga</i>, <i>H. similis</i>, and <i>H. typica</i>. Remarkably, our study reported on the presence of <i>H. poranga</i> for the first time in Vietnam. This species was found on 83.33% of the total samples with an average density of 270 individuals/100ml of soil (positive samples). In this study, the Vietnamese population of <i>H. poranga</i> was characterized based on both morphology and molecular characterization of D2-D3 expansion segment of 28S rRNA sequence. Besides, a molecular phylogenetic tree of the genus <i>Hemicycliophora</i> was also provided.Helminthologia333-338https://www.ebi.ac.uk/biostudies/studies/S-EPMC8647952biostudies-literatureFirst Report of an Important Sheat Nematode, <i>Hemicycliophora Poranga</i>, Associated with Sugar Beet (<i>Beta Vulgaris</i> L.) in Vietnam.PMC8647952Nguyen TDTrinh QPfalseFirst Report of an Important Sheat Nematode, <i>Hemicycliophora Poranga</i>, Associated with Sugar Beet (<i>Beta Vulgaris</i> L.) in Vietnam.Several species of the sheat nematodes, <i>Hemicycliophora</i> spp., have been known to cause significant damage to agricultural crops, including <i>Hemicycliophora arenaria</i>, <i>H. conida</i>, <i>H. parvana</i>, <i>H. poranga</i>, <i>H. similis</i>, and <i>H. typica</i>.
