Gyponana lamina DeLongMembracoidea : Cicadellidae
|Diseases Transmitted||Pathogen Type|
|Eastern X-disease 16SrIII-A||Phytoplasma|
|Crops Affected by Gyponana lamina DeLong|
This species is a vector of eastern X-disease virus of peach in New York. It was first reported as a vector by Gilmer and McEwen (315) in 1958 under the name “Gyponana striata (Burmeister).“ Transmission of this virus was effected from diseased chokecherry to healthy seedlings of periwinkle. The virus acquisition feeding period was 5 to 10 days and the transmission feeding period 25 days. Transmission was confirmed (Gilmer, personal communication) by transmitting the virus from diseased chokecherry to healthy chokecherry.
This species is not considered an important vector in the natural spread of this virus.
Large, robust species. Length of male 8.90—10.2 mm., female 10.8 mm.
General colour light yellowish green. Head and pronotum light yellow; elytra light yellowish green; light-orange longitudinal stripes on body.
Pygofer in lateral aspect about as long as wide, caudodorsal margin produced dorsally to narrqw angulate lobe; aedeagus in lateral aspect tubelike, curved at middle of shaft, distal half tubelike with pair of narrow terminal processes; processes curved basad, about one-half as long as shaft; gonopore terminal; style in lateral aspect simple, apical half slightly curved laterally, apices narrowed, inner lateral margin with numerous small toothlike projections; female seventh sternum in ventral aspect with caudal margin irregularly and shallowly concave.
This species, similar to
can be- distinguished by the aedeagal shaft, which is curved nearly at right angle in lateral aspect, and the style with the apical half curved slightly laterally.
