This species is a vector of the western strain of North American aster yellows virus. The first report of virus transmission by a gyponid leafhopper was made by Severin in 1946 (698). Aster yellows virus was transmitted from diseased celery to healthy celery and aster by both males and females. The minimum latent period of the virus in the insect varied from 19 to 35 days and virus retention varied from 11 to 46 days. Most of the adults lost their ability to transmit the virus after the first inoculation.
(Nielson 1968)

The evidence on virus-vector relationship and hosts of the insect indicated that hasta is not an important vector of aster yellows virus.

Species Description

Length:
Large, robust species. Length of male 8.60—9.20 mm., female 8.50—10.40 mm.
.

Colour:
General color light tan. Crown, pronotum, and elytra light tan, immaculate.

Genitalia:
Pygofer in lateral aspect slightly wider than long, caudodorsal margin produced to narrow lobe and projecting dorsally; aedeagus in lateral aspect long, tubelike, with pair of terminal, recurved processes projecting basad; gonopore apical; style in dorsal aspect distinctive, L-shaped, apex sharply attenuated; female seventh sternum in lateral aspect with caudal margin slightly concave.

Species Diagnosis

This species is related to lamina and can be separated by the aedeagal shaft, which is nearly straight in lateral aspect, and the style with apical half strongly curved laterally.
