Mosaic symptoms on leaves and fruits of pepper plants were observed in several fields around Tripoli. An isolate was obtained from a pepper field in the Faculty of Agriculture Research Station at Tripoli. It was mechanically inoculated to 43 plant species or cultivars in six plant families. Out of these only pepper cultivars and Datura metel were susceptible. Myzus persicae failed to transmit the virus. This virus has thermal inactivation point of 58-69 deg C dilution end point of 5 x 10** (-3) - 10** (-4) and longevity in vitro of 12 days. It has filamentous particles measuring 712 x 11.2 nm., and is serologically related to potato virus Y (PVY) and pepper mottle virus but not to tobacco etch virus. This virus isolate belongs to the potyvirus group, and could be a strain of PVY
