PRESENCE OF GRAPEVINE FANLEAF NEPOVIRUS IN POPULATIONS OF LONGIDORID NEMATODES AND THEIR VECTORING CAPACITY

L. Catalano, V. Savino, F. Lamberti

Abstract


Populations of longidorid nematodes collected from vineyards infected with grapevine fanleaf nepovirus (GFLV) in southern Italy were tested in ELISA to determine whether they had acquired the virus; their vector efficiency was ascertained with transmission trials. In both series of experiments GFLV was only associated with Xiphinema index and was never detected in, nor transmitted by, X, italiae, X. pachtaicum, Longidorus apulus and L. euonymus.
