Abstract

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.

Samenvatting

Uit veldwaarnemingen en onderzoek van bladmonsters in het laboratorium werd een indruk verkregen van de verspreiding van ‘passionfruit ringspot virus’ inAdenia- enPassiflora-soorten in Ivoorkust (Tabel 1 en Fig. 1). Deze gegevens doen veronderstellen datAdenia-soorten de oorspronkelijke waardplanten van het virus zijn. Introductie van het virus met de invoer vanPassiflora edulis lijkt onwaarschijnlijk. DaarAdenia-soorten gebonden zijn aan bos- en struikvegetaties en de bladluisvluchten in het drogere savannegebied van kortere duur zijn, kan de gekweekteP. edulis in het Zuiden niet, maar in het Noorden van Ivoorkust waarschijnlijk wel langere tijd gezond blijven.
