Abstract
Iris yellow spot virus (IYSV) is one of the important pathogens of onion in reported countries. Host range of this virus is very wide and transmitted by onion thrips (Thrips tabaci). In survey that was conducted in summer 2006 in onion fields of Mashhad, samples with viral symptoms and high population of thrips have been collected. Since the symptoms were similar to IYSV, special antisera of this virus have been used to check the samples in DAS-ELISA test. Results showed that the majority of collected samples were infected with this virus. This is the first report of Iris yellow spot virus (IYSV) on onion in IRAN.

Key words: Iris yellow spot virus (IYSV), Onion, DAS-ELISA and Iran
