This species is a vector of a strain of stolbur virus of clover in England. Posnette and Ellenberger (623) reported this species in 1963 as naturally infective with stolbur or another virus that was transmitted to clover. The relationship and identity of the virus are uncertain, but it appears to be closely related to typical stolbur.
(Nielson 1968)

The importance of this species as a vector is not known, but it is considered as having potential importance in the spread of certain strains of stolbur virus.
