The transmission of two strains of strawberry latent ringspot virus by populations of Xiphinema diversicaudatum (Nematoda: Dorylaimoidea)

Abstract

The ability of nine populations of Xiphinema diversicaudatum to transmit two strains of strawberry latent rings pot virus (SLRV) was examined in the laboratory. Eight of nine popUlations were relatively efficient vectors of SLRV type-British strain (SLRV-T), only a Spanish population infrequently transmitted the virus. A strain of SLRV from Prunus persica growing in Italy (SLRV-Ip) was rarely transmitted and then only by three of the nine populations used in the study. It seems likely that most populations of X. diversicaudatum have the ability to transmit SLRV-T but that most populations do not have access to the virus. Furthermore it seems likely that only X. diversicaudatum from Italy may consistently transmit SLRV-Ip.
