Also, the distribution and population densities of these nematodes were determined in potato cultivation areas of İzmir (Turkey) in 2015. Two hundred and twenty-three soil samples were collected during the survey and 32 samples were found to be infested with <i>Globodera </i> spp. and 41 samples with <i>Meloidogyne </i> spp. The identification of nematodes was made morphologically using perennial patterns of cyst/female individuals and morphometrics of second stage juveniles. Also, species specific primers were used for molecular identification. Only <i>Globodera rostochiensis </i> (Wollenweber, 1923) Skarbilovich, 1959 (Tylenchida: Heteroderidae) were found in the samples that contained cyst nematodes. Also, the root-knot nematodes, <i>Meloidogyne chitwoodi </i> Golden, O’Bannon, Santo & Finley, 1980, <i>Meloidogyne hapla </i>(Chitwood, 1949), <i>Meloidogyne incognita </i> (Kofoid & White, 1919) Chitwood, 1949, and <i>Meloidogyne javanica </i> (Treub, 1885) Chitwood, 1949 (Tylenchida: Meloidogynidae) were found. The prevalence rates of <i>Meloidogyne </i> species were determined as 2.4, 12.2, 61.0 and 24.4%, respectively. In terms of the number of individuals in soil, all <i>G. rostochiensis </i> (10 eggs/g soil) and <i>M. chitwoodi </i> (1 juvenile/250 cm <sup>3 </sup> soil) population levels were detected above the economic damage thresholds for potato production. Also, two populations of <i>M. incognita </i> (0.5-2 juvenile/250 cm <sup>3 </sup> soil) were found above the specified threshold levels.}, number={2}, publisher={Türkiye Entomoloji Derneği}, organization={T.C.
