Abstract

Nematode survey was carried out in 2019 on wild plants viz., Aeluropus lagopoides (Molleih), Ammophila arenaria (Gazzoof), Cakile maritime (Figl el-gamal), Deverra tortuosa (guezah), Euphorbia paralias (Sakrran), Inula crithmeides (Golden samphire), Lotus polyphyllus (Qam el- gamal or Qrana), Ononis vaginalis (Hotaiba), Pancratium maritimum (Bosseil), Polygonum equisetiforme (Horsetail knotweed), Thymelaea hirsute (Mithnaan), and Zygophyllum album (Ratrayt), colonized the coastal sand dunes habitat of mersa matruh, Egypt. specimens of root-lesion nematodes (Pratylenchus spp.) were collected from rhizosphere soil of D. tortuosa Synonym: Pituranthos tortuosus (Desf.) Benth. & Hook f. Asch. & Schweinf herb (family: Apiaceae, old family: Umbelliferae). Root-lesion nematode was identified based on morphological characteristics of females. According to available literature, this is the first report of Pratylenchus on wild plant (D. tortuosa) growing in 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-parasitic nematodes and it is advisable to investigate the nearby cultivated plants.
