|Crops Affected by Chlorotettix similis DeLong 1918c: 14|
This species is a vector of the western strain of North American aster yellows virus. Severin (1947 and 1947) [701, 703] was first to report this species as a vector of this virus when he obtained 23-percent transmission from diseased celery to healthy celery. The leafhopper fed for 10 days on the inoculum and then was transferred singly and in multiple lots to successive celery plants. Attempts to transmit curly top virus by this species were not successful.
This species is not considered an important vector in the natural spread of this virus.
Large, robust species. male 7.50—8.00 mm., female 8.20—8.80 mm.
General color yellowish tan. Crown, pronotum, and scutellum yellowish tan; elytra subhyaline.
Pygofer in lateral aspect about 1½ times as long as wide, caudal margin broadly convex; aedeagus in lateral aspect recurved, distal three-fourths narrow, elongate, tubelike, with four terminal needlelike processes, outer processes extremely long, three times as long as inner processes; gonopore apical; style in dorsal aspect with prominent subapical spine on outer margin; female seventh sternum in ventral aspect with caudal margin deeply notched at middle.
to which it is similar in general habitus,
can be easily separated by the pygofer, which lacks the long ventral spine, and the aedeagus, whose shaft is long and narrow and terminated with two pairs of narrow processes. Severin (1947)
and DeLong and Severin (1947)
illustrated the adult and genitalia of this species, respectively.
