Feeding characteristics:  This pest attacks citrus, avocado, and potato plantsBoth the adults and nymphs feed on cell sap, or juices, in twigs and foliage, causing eventual death of the affected parts after they wilt and lose their color.

The mealybug coats the foliage with thick honeydew, which is a growing medium for black moldHoneydew is also a food for ants, which end up carrying the mealybugs from plant to plant.
