The distribution of passionfruit ringspot virus in its main host plants in Ivory Coast

A field survey and testing of leaf samples have given an impression of the distribution of passionfruit ringspot virus in twoAdenia and twoPassiflora spp. in Ivory Coast. The data suggest thatAdenia spp. are the original host plants of the virus. Introduction to Ivory Coast of the virus withP. edulis seems unlikely. Since theAdenia spp. prefer forest and shrub vegetations and aphid flights are shorter in the dryer savannah areas of the North, the cultivatedP. edulis has chances to remain healthy over a prolonged period of growth, which is excluded in the South of the country.
