This species is a vector of rubus stunt virus in England. It is a suspect vector of the same virus in the Netherlands. It was first reported as a vector of this virus in 1961 by the East Mailing Research Station (228). Transmission was effected to blackberry only.
(Nielson 1968)

This species is considered an important vector in the transmission of rubus stunt virus from blackberry to blackberry.

Species Description

Medium size, robust species. male 4.30—4.50 mm., female 5.00—5.10 mm.

General colour dark brown. Crown light brown with two large black spots on anterior margin; pronotum light brown with dark brown irregular patches or markings; elytra translucent, veins dark brown to black.

Pygofer in lateral aspect about as long as wide, caudoventral margin with distinct, long spine projecting dorsad to dorsal margin of pygofer (type); aedeagus in lateral aspect broad basally, tubebike, curved laterally, attenuated apicably; gonopore subapical; style in dorsal aspect long and slender, apical two-thirds tube-like, apex curved laterally; female seventh sternum in ventral aspect with lateral margins converging to form broad, angulate, convex caudal margin.

Species Diagnosis

This species is closely related to fuscula and is difficult to separate from it on the basis of the male genitalia. In 1964, Wagner (844) distinguished the species by the shape of the lorum. In scotti it is very narrow and elongate. There is considerable color variation among populations within species, and although Wagner illustrated color forms, there appeared to be some overlapping between species.
