Abstract

 In order to identify and determine the DISTRIBUTION of HETERODERA species, 130 soil and infected root samples were collected from SUGAR BEET fields in Mashhad region. Soil samples were washed and NEMATODEs were separated from soils and tissues by De Grisse and Fenwick methods. Prepared slides were studied based on the morphological and morphometrical characteristics. In this study, HETERODERA schachtii, H. trifolii, H. rosii, H. avenae, H. mani, H. iri, H. carotae, H. cruciferae were identified from different SUGAR BEET fields. Two species were separated from soil of SUGAR BEET fields and also roots of carrot and rape (Eruca sativa), respectively. Frequency and DISTRIBUTION of the first two species (H. schachtii and H. trifolii) were more than other species and they were found in the soil as well as root samples.
