Mealybugs
Mealybugs are soft and oval, have a white waxy covering, and are roughly a ¼” long. Mealybugs appear on trunks and cordons in the spring. As temperatures warm in summer, they can be found on all parts of the vine including leaves and clusters. Ants and mealybugs are known to have a symbiotic relationship. Ants will protect and fend off predators, as mealybugs excrete honeydew. |
Lacewing (Chrysoperla spp.) are generalist predators, meaning they target a broad spectrum of small insects and mites. In grapes, lacewing can be used to combat mites, mealybugs, leafhoppers, whiteflies, and caterpillars. All lacewing larvae are predaceous, but adults of lacewings are not predaceous and feed on nectar and pollen. Larvae of the lacewing attack prey and suck their bodily fluids.
