Pink hibiscus mealybug

Definition

A polyphagous mealybug species (Maconellicoccus hirsutus) in the family Pseudococcidae, native to Southeast Asia and now invasive across tropical and subtropical regions worldwide. Females are pinkish and covered in white waxy filaments; colonies form dense masses on stems, leaves, and fruit, causing direct damage through sap feeding and indirect harm via sooty mold growth on honeydew excretions. The species is a major quarantine pest of hibiscus, citrus, cotton, and numerous other crops.

Etymology

Common name derives from its characteristic pink body color and its type host association with Hibiscus spp.; 'mealybug' refers to the powdery wax secretion typical of Pseudococcidae.

Example

In the Caribbean, pink hibiscus mealybug infestations on Hibiscus rosa-sinensis can cause complete defoliation and shoot dieback, with waxy colonies visible as white, cottony masses along stems and leaf axils.

Usage Notes

The common name is sometimes shortened to 'hibiscus mealybug,' which can cause confusion with other mealybug species on hibiscus; 'pink hibiscus mealybug' or 'PHMB' is preferred in regulatory and scientific contexts. Not to be confused with the citrus mealybug (Planococcus citri) or longtailed mealybug (Pseudococcus longispinus), which differ in body shape and waxy filament arrangement.
