Abstract

Transmission properties of Iranian wheat stripe virus (IWSV), a tentative member of the genus Tenuivirus, were studied. Results showed that similar to other tenuiviruses, IWSV multiplies in its vector, Unkanodes tanasijevici. In bioassay experiments, IWSV transmission rate by individual U. tanasijevici showed an increase with time after acquisition. IWSV was transovarially transmitted to 88–100% of progeny. The nymphs continued to be infective in the adult stage but with decreased efficiency. Males and females transmitted the virus with equal efficiency. Transmission properties of IWSV confirm the position of the virus in the genus Tenuivirus.
