Abstract :Soils collected from 28 canola fields in Malkara, Süleymanpaşa, Muratlı, Hayrabolu, and Ergene districts of Tekirdağ were examined for the determination of nematode fauna. In the soils taken from 0-60 cm depth in each field, 28 genera of nematodes were recovered by the modified Baermann Funnel method. Of these, eight were bacterivores, three were fungivores, five were omnivores, three were predators, and the rest were plant-parasitic species. Nematodes in survey areas had colonizer-persister values ranging from 1 to 5. The maturity and community indices were also calculated and four were found as follows: Enrichment insert ignore into journalissuearticles values(E);: 34.6±15.2; Maturity insert ignore into journalissuearticles values(MI);: 2.68±0.05; Plant parasite insert ignore into journalissuearticles values(PPI);: 2.69±0.39; Shannon\`s diversity insert ignore into journalissuearticles values(H\`);: 1.80±0.26. The predominant taxa were Filenchus insert ignore into journalissuearticles values(100%);, Mesodorylaimus insert ignore into journalissuearticles values(92%);, and Ditylenchus insert ignore into journalissuearticles values(85.1%);. In terms of density in 100 cm3 soil, the highest values were found in the genus Acrobeloides insert ignore into journalissuearticles values(192 individuals/100 cm3 soil);, and the number of Ditylenchus insert ignore into journalissuearticles values(57 individuals/100 cm3 soil);, Filenchus insert ignore into journalissuearticles values(180 individuals/100 cm3 soil);, and Mesodorylaimus insert ignore into journalissuearticles values(165 individuals/100 cm3 soil);, individuals were also found high in some soils. The plant parasitic nematodes identified in canola fields include Boleodorus tylactus, Filenchus cylindricus, Filenchus sheri, Filenchus thornei, Geocenamus brevidens, Helicotylenchus digonicus, Malenchus fusiformis, Paratylenchus variabilis, Pratylenchoides alkani, Rotylenchus robustus, Tylenchorhynchus annulatus, and Tylenchorhynchus cylindricus.
