This species is a vector of the western strain of North American aster yellows virus. In 1945, Severin (696) was first to report transmission of this virus by producing infections from diseased celery to healthy celery plants. Insects were fed for 10 days or longer on inoculum and males transmitted the virus to 7 of 13 and females to 8 of 14 celery plants. Percent transmission ranged from 20 to 100.
This species is not considered an important vector in the natural spread of this virus, although it has potential importance.
Medium size, robust species. male 5.50—6.60 mm., female 5.50—6.80 mm.
General colour light brown to dark brown with numerous, dark, fine reticulations on body. Crown tan with reticulations; pronoturn light brown, reticulated; elytra ivory with numerous fine dark-brown or black reticulations.
Pygofer in lateral aspect about 1½ times longer than wide, caudoventral margin with distinct broad spine, curved dorsoposteriorly; aedeagus in lateral aspect broad basally, narrowed subapically, with broad spinelike processes subapically, apex curved laterally, shaft with apex sharply pointed in ventral aspect with paired lateral spines near apex; style extremely large, longer than length of pygofer; female seventh sternum in ventral aspect with caudal margin deeply and broadly excavated along middle to form two distinct lobes.
This is the only species in the genus
that is a known vector of a plant virus. It can be distinguished from other vector species by the characters in the key to the genera. The male genitalia were illustrated by DeLong and Severin in 1945
Crowder in 1952
and Beirne in 1956
Color plates of the adults were presented by Severin in 1945.
