|Crops Affected by Psammotettix lividellus (Zetterstedt 1840a: 290 )|
This species is a reported vector of little cherry virus in British Columbia. In 1960, Wilde (861) reported one ease of transmission of this virus from diseased cherry to healthy cherry in greenhouse tests. Results have not been confirmed.
This species is not considered an important vector of this virus. Further testing is necessary to confirm this species as a vector.
Small, linear species. Length of male 3.20—3.80 mm., female 3.60—4.00 mm.
General color tan. Crown tan with light-brown patches on disk; pronotum tan to light brown; elytra tan, veins yellow or ivory.
Pygofer in lateral aspect about 1% times as long as wide,.
Pygofer in lateral aspect about 1% times as long as wide, caudoventral margin produced posteriorly to narrow fingerlike lobe; aedeagus in lateral aspect simple, narrow, tubelike, slightly recurved; gonopore large, subapical on ventral surface of shaft; style in dorsal aspect with apices short, curved laterally, expanded apically; female seventh sternum in ventral aspect with caudal margin slightly bibbed medially.
This species is similar to
in general habitus, but can be distinguished by the aedeagus with the shaft narrowed throughout. Further characterization of the genitalia was given by Beirne (1956).
