|Crops Affected by Pagaronia furcata Oman|
This species is a vector of Pierce’s disease virus of grape in California. It was first reported as a vector of this virus by Frazier and Freitag (275) in 1946. It was not an efficient vector, although it transmitted the virus from diseased grape and alfalfa to 19 percent of healthy grape and alfalfa plants tested. These results have not been confirmed.
The species is regarded as an unimportant vector of Pierce’s disease virus of grape.
Large, slender species. Length of male 8.00—8.90 mm., female 8.50—9.40 mm.
General color light yellow. Crown with Seven distinct black spots; pronotum yellow with three transverse spots of dark short lines; elytra yellow with orange longitudinal stripes.
Pygofer in lateral aspect about 11/4 times longer than wide, caudoventral margin narrowed to convex lobe; aedeagus in lateral aspect long, narrow, curved laterally, tubelike, with pair of fine terminal processes projecting distad; style in dorsal aspect with apex narrow and curved laterally; gonopore subterminal on ventral surface of shaft; female seventh sternum in ventral aspect with truncate caudal margin, slightly notched at middle.
to which it is closely allied,
can be distinguished by the paired distal processes of the aedeagus, which are projecting distad in lateral and ventral aspects.
