The permanent slides were prepared from the extracted nematodes. After microscopic consideration, the useful measurements and drawing were attained by using a drawing tube attached to the microscope. In this study 27 species belonging to 15 genera were identified using morphological and morphometrical characters as following: Aphelenchoides asterocaudatus, A. bicaudatus, A. sacchari, Aphelenchus avenae, Basiria graminophila, Boleodorus thylactus, Criconemoides xenoplax, C. curvatum, Ditylenchus myceliophagus, Filenchus facultativus, F. vulgaris, Helicotylenchus digonicus , H. dihystera, H. exallus, H. pseudorobustus, H. vulgaris, Nagelus obscurus, Ogma civellae, Paratylenchus nanus, Pratylenchus loosi, P. neglectus, P. jaehni, P. zea, Psilenchus hilarulus, Seinura lii, S.prospera , Tylenchulus semipenetrans.
