The Distribution of passionfruit ringspot virus in its main host plants in lvory Coast, 1975
Abstract
A field survey and testing of leaf samples have given an impression of the distribution of passionfruit ringspot virus in two Adenia and two Passiflora spp. in Ivory Coast. The data suggest that Adenia spp. are the original host plants of the virus. Introduction to Ivory Coast of the virus with P. edulis seems unlikely.
Since the Adenia spp. prefer forest and shrub vegetations and aphid flights are shorter in the dryer savannah areas of the North, the cultivated P. edulis has chances to remain healthy over a prolonged period of growth, which is excluded in the South of the country.
