Several parasites and predators keep mealybugs under natural control. At least five species of parasitic
wasps attack grape mealybug in California. The effectiveness of parasites varies considerably from time
to time and place to place. One common species is the tiny wasp, Acerophagus notativentris. Mealybugs
parasitized by this wasp exhibit multiple emergence holes that are easily seen with a hand lens.
Predators of mealybugs important in keeping populations in check include mealybug
bugs, and spiders.
