Regulated Deficit Irrigation And Density Of Erythroneura Spp. (Hemiptera: Cicadellidae) On Grape, Michael J. Costello
Horticulture and Crop Science
This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology of a cultivated perennial crop, to improve vegetative balance and crop quality. Erythroneura spp. are known to respond negatively to vine water stress, and the second generation of leafhoppers begins during a potential RDI initiation period, between berry set and veraison (beginning of fruit …
