Dw. Paxton et Hg. Thorvilson, OVIPOSITION OF 3 ERYTHRONEURA SPECIES ON GRAPE LEAVES IN WESTERN TEXAS, The Southwestern entomologist, 21(2), 1996, pp. 141-144
Ovipositional sites and patterns of three species of Erythroneura (Hom
optera: Cicadellidae) leafhoppers that infest grape vineyards on the T
exas High Plains were studied. The three species, Eryrthroneura colora
densis (Gillette), Erythroneura vulnerata Fitch, and Erythroneura zicz
ac (Walsh), significantly oviposit greater numbers of eggs in top surf
aces, in the mesophyll portion near vascular bundles, and in bottom su
rfaces of leaves under the epidermis, respectively. Ovipositional site
s may be used to identify the leafhopper species that infest vineyards
on the Texas High Plains.
