|Crops Affected by Aceratagallia longula van Duzee|
This species is a vector of the New York strain of potato yellow dwarf virus in the Eastern United States. Under the name of “Aceratagallia lyrata (Baker), longula was first reported as a vector of this virus by Black in 1944 . Transmission was effected from diseased crimson clover to healthy crimson clover plants. Details of the transmission tests were not given. Specimens used in the transmission tests in New Jersey were collected from California. Transmission of the virus by longula has not been confirmed by other workers, nor has the species been demonstrated as a vector of other plant viruses.
Results of experimental transmission in New Jersey tests suggest that the species is a potentially important vector of potato yellow dwarf virus in the Western United States.
Small, somewhat linear species. male 3.55—3.75 mm., female 3.55—4.00 mm.
General color light brown to tan. Vertex with two distinct dark round spots; pronotum light brown; elytra with broken markings along commissure and claval veins.
Pygofer in lateral aspect about 11/3 times longer than wide, caudal margin strongly produced posteriorly at about middle to large broadly angled lobe; 10th segment with pair of long, straight spines directed posteroventrad along inside of caudal submargin of pygofer; aedeagus in lateral aspect simple, basal half of shaft broad, apical half tubelike, curved laterally at apex; gonopore terminal; style in dorsal aspect with sides of distal half parallel, inner margin coarsely serrate, prominent, sharp, subapical spine on outer margin; female 7th sternum in ventral aspect with caudal margin truncate and slight1y sinuate.
This species, similar to
can be distinguished by the style with its short subapical spine.
