Occurrence of plant parasitic nematode species in important crops in the Southeast Anatolia Region of Turkey

The Southeast Anatolia Region is one of the major agricultural production areas of Turkey where durum wheat, barley, vegetables and some fruit crops are grown. This study aimed to determine the important plant parasitic nematode species affecting the most commonly cultivated plants in this region. Soil samples were collected in the wheat growing areas of ？anl？urfa, Mardin, ？？rnak, Kilis Provinces between May and June in 2011-2012, and pistachio, barley, grapevine, wheat, tomato, watermelon, melon, cotton and tobacco fields of Ad？yaman in May, July, October in 2010-2011. The study also reviewed the list of nematode species previously identified in the region. Aphelenchus avenae Bastian 1965, Anguina tritici (Steinbuch) Filipjev, Merlinius brevidens (Allen, 1955) Siddiqi, 1970, Pratylenchus neglectus (Rensch, 1924) Filipjev & Schururmans Stekhoven 1941, P. thornei Sher & Allen, 1953, Paratrophurus acristylus Siddiqi et Siddiqui, 1983 and Pratylenchoides alkani Yüksel, 1977 were the most common species found. This study reports Ditylenchus longicauda Geraert & Chi, 1988, Rotylenchus echelimae Scotto La Massese & Germani, 2000, Filenchus hamatus (Thorne & Malek, 1968) Raski & Geraert, 1987, Helicotylenchus crassatus Anderson, 1973, Helicotylenchus goodi Tikyani et al., 1969, and Helicotylenchus oleae Inserra, Vovlas & Golden, 1979 for the first time in Turkey
