Pepper Veinal Mottle Virus in Ivory Coast, 1973
Abstract
A mosaic and stunt disease of chilli pepper (Capsicum frutescens) in Ivory Coast was found to be caused by pepper veinal mottle virus, a member of the potato virus Y group, recently
described from chilli pepper in Ghana. The Ivory Coast isolate was first transmitted by aphids to Physalis floridana and subsequently maintained by mechanica] inoculation in P. floridana and Nicotiana megalosiphon. The host range includes mainly Solanaceae, but Solanum species were not or very little susceptible. Aphis gossypii, A. spiraecola and Toxoptera citricidus transmitted the virus in a non-persistent manner. No dodder transmission was found.
Serological relationship with onion yellow dwarf virus and Columbian Datura virus was established.
