The Vine Mealybug (VMB) is a serious insect pest of grapes grown in California. There are only a few chemical management options available, and the more that these are used, the higher the likelihood is of insecticide resistance developing. Proper monitoring is a necessary step in assuring premium wine grape growers that their vines are clean and their management plans are effective.
