Mango mealybug

Definition

A polyphagous, sap-sucking scale insect that is a major pest of mango (Mangifera indica) and over 60 other plant species across Asia. Despite its common name, it belongs to the family Monophlebidae (giant scale insects), not Pseudococcidae (true mealybugs). Nymphs and females feed on phloem sap from inflorescences, tender leaves, shoots, and fruit peduncles, causing inflorescence desiccation, fruit drop, and reduced yield. Heavy infestations produce copious honeydew that supports sooty mold growth, further compromising photosynthesis and fruit quality.

Etymology

From 'mango' (its primary cultivated host) + 'mealybug' (misleading common name based on superficial resemblance to mealybugs in the family Pseudococcidae, with waxy secretions giving a 'mealy' appearance).

Example

In Indian mango orchards, peak mango mealybug populations coincide with flowering; integrated management relies on conserving the parasitoid wasp Anagyrus dactylopii and the predatory ladybird Cryptolaemus montrouzieri, combined with banding tree trunks to block crawler migration.

Usage Notes

The common name is taxonomically misleading; specialists emphasize that this species is a monophlebid scale insect, not a true mealybug (Pseudococcidae). The distinction matters for identification and management, as Monophlebidae have different life histories and often respond differently to insecticides than Pseudococcidae. When communicating with growers or in extension materials, clarify the taxonomic discrepancy to avoid confusion with true mealybug pests such as Planococcus citri or Maconellicoccus hirsutus.
