|Crops Affected by Aceratagallia curvata Oman|
This species is a vector of the New York strain of potato yellow dwarf virus in the Eastern United States Transmission of this virus from crimson clover to crimson clover by curvata was first reported by Black in 1944 . Specimens were collected from California for the tests in New Jersey. Details of the transmission experiments were not given. No evidence of transmission of other strains of potato yellow dwarf or other viruses by this species or confirmation of Black’s work by other workers has been reported.
Small, robust species. Length of male 2.90—3.20 mm., female 3.20—3.40 mm.
General color light tan. Crown with two distinct black spots on anterior margin; pronotum light tan; elytra with light fuscous markings on veins.
Pygofer in lateral aspect slightly longer than wide, caudal margin produced posteriorly at about middle to bluntly angled lobe; 10th segment with pair of long straight spines directed posteroventrad along inside of caudal submargin of pygofer; aedeagus in lateral aspect simple, apical half of shaft narrow, tubelike, slightly curved laterally at apex; gonopore terminal; style in dorsal aspect with distal third expanded along inner coarsely serrate margin and curved laterally, apex foot shaped; female 7th sternum in ventral aspect with caudal margin truncate and slightly notched at middle.
This species is allied to obscura and can be separated by the apex of the style, which is curved laterally and expanded on its inner serrate margin.
