US: New Pest Invades Western Vineyards
Nov 30, 2012 6
(Wines&Vines) - The University of California Cooperative Extension is warning Northern California grapegrowers that their vineyards may be under attack from a newly invasive pest. The Virginia Creeper leafhopper (VCLH) is related to the familiar western grape leafhopper in behavior, appearance and appetite—but unfortunately, VCL (Erythroneura ziczac Walsh) apparently is not on the menu for the beneficial Anagrus wasps that parasitize the eggs and inhibit the spread of native leafhoppers.
