Mexican fruit fly

Definition

A species of true fruit fly (Tephritidae), *Anastrepha ludens*, native to Mexico and Central America and a major pest of citrus and other commercial fruits. Adults are distinguished by a dark brown scutum with a yellow stripe and wings with a distinctive S-shaped band and inverted V-shaped pattern. Larvae tunnel through fruit pulp, causing internal decay and rendering produce unmarketable; infestations trigger quarantine protocols in the United States and elsewhere.

Etymology

From geographic range (Mexico) plus 'fruit fly' for the family's common association with ripening fruit; scientific epithet *ludens* from Latin 'playing' or 'sporting', possibly referring to wing pattern.

Example

Detection of a single Mexican fruit fly in the Rio Grande Valley can prompt an eradication program involving millions of sterile male releases and quarantine restrictions on citrus movement.

Usage Notes

Distinguished from Drosophila 'fruit flies' (vinegar flies) by family, size, and economic impact; *A. ludens* is larger and more robust than typical Drosophila species. Closely related to and sometimes confused with Caribbean fruit fly (*Anastrepha suspensa*) and papaya fruit fly (*Anastrepha curvicauda*), though wing patterns and host preferences differ.
