Anastrepha suspensa

Definition

A tephritid fruit fly species (Diptera: Tephritidae) native to the Caribbean region and now established in Florida, commonly known as the Caribbean fruit fly or guava fruit fly. Adults lay eggs in mature to overripe fruits; larvae feed internally, causing significant economic damage to guava, mango, and other tropical and subtropical fruit crops. The species is a major quarantine pest subject to regulatory control programs.

Etymology

From Greek anastrepho (to turn up or back) + Latin suspensa (hanging), referring to wing pattern or posture; specific epithet from Latin suspensus (suspended, doubtful), likely alluding to original taxonomic uncertainty.

Example

Detection of a single Anastrepha suspensa larva in a commercial mango shipment triggers mandatory cold treatment or fumigation requirements under international phytosanitary regulations.

Usage Notes

Distinguished from the Mediterranean fruit fly (Ceratitis capitata) and other Anastrepha species by wing pattern, host range, and geographic distribution. Common names vary regionally; 'Caribbean fruit fly' is preferred in regulatory contexts to avoid confusion with Bactrocera species also called 'guava fruit flies' in Asia-Pacific.
