A field survey was carried out in 34 greenhouses of cucumbers in the Syrian coast in 16 villages belonging to the governorates of Latakia and Tartous, in order to determine the incidence and severity of root-knot nematode, in addition to determining the structure of the species in the adult female by perineal patterns morphology and taking the  biometric measurements of the larvae of the second stage, since March until the end of June of the season 2014/2015. The results of the study on root samples showed that the incidence of root-knotted nematodes ranged between (20- 100%) with an average of 59%. The severity of the infection according to the scale (Bridge and Page, 1980) was 0.4- 4.2 with an average of 1.67. The results showed the presence of three main species belong to the genus Meloidogyne:  M. incognita, M. javanica M. arenaria, and the percentage of the prevalence of 50.98%, 47.55%, 1.47% respectively. While unrecorded species M. hapla in study areas.

 Key words: Root- knot nematode, Severity of infection, Species structure, Cucumber, Greenhouse.
