Papaya Mealybug

Identification and host relationships

The papaya mealybug feeds on a range of tropical fruit and ornamental plants, rather than on papaya alone. Females and their egg masses are conspicuous in infestations, while adult males are small and winged. Reliable separation from similar mealybugs depends on microscopic characters. Host-dependent development has been studied experimentally, and biological control has been central to management programs outside Kauaʻi; those outcomes do not establish local control levels.
