Tylenchs (Nematoda: Tylenchida) from wheat fields in Isfahan Province

In order to identify the nematodes (order: Tylenchida) in wheat fields, 54 soil, root and ear samples were collected from different localities of Isfahan province. The nematodes were extracted by centrifugal flotation technique. Then they were fixed according to the De grisse method. Investigation of specimens revealed 17 species belonging to 12 genera of order Tylenchida. The genera Geocenamus, Helicotylenchus and Pratylenchus have been most frequently observed nematodes, respectively. Two species Seinura demani and Tylenchorhynchus teeni are first species records for Iran. Because of importance and lack description, morphological and morphometrical information and drawing for each species with description of Heterodera filipjevi are discussed.
