Abstract :
In this study, the prevalence, infestation ratio and population densities with distribution of citrus nematodes (Tylenchulus semipenetrans) (Cobb, 1913) growing areas of satsuma mandarin in Izmir province was determined. The main materials of this study constitute soil samples, plant materials and nematodes collected from sampled areas. 178 soil samples and plant roots collected from growing areas of satsuma mandarin in different districts of Izmir province were analyzed. The infestation ratio of citrus nematode in the satsuma mandarin growing areas were detected as 97,30%; 94,83%; 75,47%; 75,00% and 50,00% in Selcuk, Menderes, Seferihisar, Karaburun and Urla, respectively; and 100,00 %in other five districts (Balcova, Guzelbahce, Narlidere, Menemen, Torbali). According to these results, 89,33% of the total survey area was found as infestation. The population densities of J2 stage and male of citrus nematode individuals in 100 g soil was determined at 543; 880; 246; 120; 707; 407; 248; 1436; 740 and 290 in Balcova, Guzelbahce, Narlidere, Karaburun, Menderes, Menemen, Seferihisar, Selcuk, Torbali and Urla, respectively.
