Technical Abstract: Vine mealybug, an insect pest capable of causing direct and indirect damage to grape vineyards, costs California growers millions of dollars annually. Insecticide sprays used to manage the pest provide inconsistent results, and sustainable methods of control are needed. A previous study identified a single grape accession with resistance to other mealybug species, but did not evaluate vine mealybug. This work aims to evaluate the susceptibility of grape cultivars, rootstocks, and species to vine mealybug.
