A Field Study on Determination of Nematode Diversity in Canola Fields in Tekirdağ, Turkey

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