Nematological survey was carried out in 2019 on wild plants viz., Aeluropus lagopoides, Ammophila arenaria, Cakile maritime, Deverra tortuosa, Euphorbia paralias, Inula crithmeides, Lotus polyphyllos, Ononis vaginalis, Pancrtium maritimum, Polygonum equisetiforme, Thymelaea hirsuta and Zygophyllum album, colonized the coastal sand dunes habitat of Mersa Matruh, Egypt. Specimens of lesion nematode (Pratylenchus spp.) were collected from rhizosphere soil of Deverra tortuosa Synonym: Pituranthos tortuosus (Desf.) Asch. and Schweinf herb (family: Apiaceae, old Umbelliferae). Lesion nematode was identified based on morphology of females. According to available literature, this is the first report of Pratylenchus on wild plant (Deverra tortuosa) colonized Egypt. More surveys are needed to identify other genera or species of phytonematodes that might occur in Egypt, including weeds, grasses and wild plants in desert areas, also the dissemination of lesion nematode must be explored as well as other plant-feeding nematodes and it is advisable to investigate the nearby cultivated plants.
