This species is a vector of the western strain of North American aster yellows virus. Severin and Frazier in 1945  were first to report this species as a vector of this virus in California. Transmission to onion was effected, and later Severin in 1947  obtained transmissions from diseased celery and aster to healthy celery and aster. The average percentage of infection from celery to celery varied from 29.8 to 51.9 and from aster to aster 9.1 to 18.7. The virus was also transmitted from celery to aster and aster to celery. Percent inoculations were always higher on celery.
The minimum latent period of the virus in adults ranged from 11 to 26 days and averaged 18.4 days. Only one female retained the virus for 51 days whereas other vectors caused only initial infections. Attempts to transmit curly top virus of sugarbeet and Pierce’s disease of grape were not successful. This species was able to induce viruslike symptoms on celery that were caused by toxic saliva (Severin 1947) .
This species is considered of some importance in the spread of aster yellows virus in California and of potential importance of the virus elsewhere.
Medium size, robust species. male 5.10—5.90 mm., female 5.80—6.20 mm.
General colour polished tan to dark brown. Crown tan; pronotum tan, unicolorous; elytra brown, apex dark brown.
Pygofer in lateral aspect about as long as wide, caudal margin broadly truncate; aedeagus in lateral aspect with narrow, paired basal processes on ventral margin, processes curved laterodistad in ventral aspect; aedeagal shaft broad basally, tubelike distally; gonopore apical; style in dorsal aspect constricted at middle, apex shallowly concave, several small teeth on inner apical margin; female seventh sternum in ventral aspect with caudal margin truncate, notched medially.
This is the only species in the genus
that is a reported vector of plant viruses.
