A disease causing crinkling and stippling on groundnut plants was Observed in the south of Ivory Coast. The disease was sap transmissible. Attempts to transmit the disease by Aphis craccivora, A. citricola and A. gossypii failed. The first observation on biological properties and electron micrographs showed that this disease might be a new disease of groundnut, caused by a cariavirus, and named groundnut crinkle virus.
