This species is a vector of mosaic virus of winter wheat. First reports of transmission of this virus appeared in 1939 by Zazhurilo and Sitnikova (890). Confirmation was subsequently reported by Zazhurilo and Sitnikova in 1940 and 1941 (891, 892, 893) and Razvyaskina in 1962 (631), who determined that the first generation was mainly responsible for the spread of the virus of winter wheat. Only nymphs are capable of transmitting the virus. Transovarial transmission was demonstrated by Shaskolskaya in 1962 (715). The percentage of infected insects in the progeny of infected parents was 76.7.
This species is the most important vector in the natural spread of winter wheat mosaic in Russia.
Small, linear species. male 3.60—3.80 mm., female 3;70—4.00 mm.
General colour tannish brown. Crown tan with patches of light brown on disk; pronotum tannish brown; elytra tan with cells bordered with dark brown, veins yellow or ivory.
Pygofer in lateral aspect slightly longer than wide, caudoventral margin produced posteriorly to broad, convex lobe; aedeagus in lateral aspect curved, shaft tubelike; gonopore on ventral surface, near apex, bifid apically in ventral aspect; style in dorsal aspect shorter than connective, apex curved laterally; female seventh sternum in ventral aspect with caudal margin distinctly truncate.
species is similar to
in general habitus and genital characteristics and is difficult to separate. The aedeagus is distinctive, and in
the apex is rounded in lateral aspect and rounded or truncate in ventral aspect.
All the American references to this species are erroneous and probably referred to alienus.
