On the Transmission of Grape Fanleaf By Xiphinema Index

Abstract

Grape fanleaf virus persists for long periods in the long-lived adult female life-stage of the vector, Xiphinema index, but the virus does not persist through the egg or through the moult. This is in common with other NEPO viruses but there is evidence to suggest that the mechanism of virus transmission differs basically between Xiphinema and Longidorus vectors.
