Abstract

To identify the horticultural of plant parasitic nematodes in Northern Khorasan province, 170 soil and plant root samples were collected during different seasons of years 2009 and 2010. Nematodes were extracted through centrifugal-flotation method, specimens then being fixed according to modified Seinhorst method and transferred to glycerin before making measurements (De Grisse, 1969). Throughout the study 12 species from genus Filenchus namely: F. afghanicus (Khan & Khan, 1978) Siddiqi, 1986, Filenchus andrassyi (Szczygiel, 1969) Andrassy, 1979, F. baloghi (Andr?ssy, 1958) Siddiqi, 1986, F. cylindricaudus (Wu, 1969) Siddiqi, 1986, F. facultativus (Szczygiel, 1970) Raski & Geraert, 1987, F. misellus (Andr?ssy, 1958) Raski & Geraert, 1987, F. paravesiculosus Karegar & Geraert, 1998, F. polyhypnus (Steiner & Albin, 1946) Meyl, 1961, F. sandneri (Wasilewska, 1965) Raski & Geraert, 1987, F. vulgaris (Brzeski, 1963) Lownsbery & Lownsbery, 1985, F. elegantulus Raski & Geraert, 1986, F. longicaudatulus Zell, 1988 were identified from which the last two species are new /recirds for nematode fauna of Iran.
