First Report of an Important Sheat Nematode, Hemicycliophora Poranga, Associated with Sugar Beet (Beta Vulgaris L.) in Vietnam

First reports of Hemicycliophora poranga, Helicotylenchus dihystera and Tylenchorhynchus zeae (Tylenchomorpha) from Greece and further records of four other nematode species

Nematode samplings in various areas and crops of Greece were carried out and the recovered nematode species were characterized using morphological and molecular data. Seven species of plant-parasitic nematodes were recovered, three of which are reported for the first time in Greece, including Hemicycliophora poranga, Helicotylenchus dihystera and Tylenchorhynchus zeae. Four other recovered species had already been reported in Greece, including Bitylenchus hispaniensis, Helicotylenchus microlobus, Nanidorus minor and Scutellonema brachyurus. D2-D3 segments of 28S rRNA gene for all of these nematode species are provided.
