OVIPOSITION OF 3 ERYTHRONEURA SPECIES ON GRAPE LEAVES IN WESTERN TEXAS

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.
