Özet: This study aims to determine the seasonal population fluctuations of two important plant parasitic nematodes root-knot nematodes (Meloidogyne spp.) and root-lesion nematodes (Pratylenchus spp.) that causing economic losses in plants in the world in maize (Zea mays L.) growing areas. Population fluctuations of root-knot nematode infective second-stage larvae (J2) and root lesion nematode individuals (larvae+female) in soil were monitored monthly in two different maize growing fields (A and B) during 2016 and 2017 in Ordu province of Turkey. In the result of the study, the highest population were observed in October 2017 as 462 (J2/100 cm3 soil) for Meloidogyne spp. and 38 individuals /100 cm3 soil for Pratylenchus spp. at field A. The highest population of Meloidogyne spp. were observed as 203 J2/100 cm3 soil in December 2016, while Pratylenchus spp. in August for 63 individuals/100 cm3 soil at field B. In both fields, populations of root-knot nematodes in the soil were increased significantly in autumn months, but continued in low levels in summer. The root lesion nematodes population density showed a positive correlation with the soil temperature and increased at a certain level throughout the year.
