Abstract

To identify plant parasitic nematodes of tomato fields in North Khorasan Province during
2009 and 2010, 120 soil samples were collected from tomato rhizospheres. The nematodes
were extracted from soil through centrifugal flotation technique. The extracted nematodes were
transferred into glycerin. Permanent slides were mounted. The nematodes were identified
through their morphological and morphometrical characteristics. A significant diversity was
observed among species belonging to Ditylenchus. Three species of Ditylenchus were
identified as follows: D. acutatus, D. medicaginis and D. tenuidens from among these species,
D.acutatus and D. tenuidens were the first time reports from Iran.
