Mexican Fruit Fly

The Mexican fruit fly is native to southern and central Mexico. Each year, the pest enters the Lower Rio Grande Valley’s 27,000 acres of commercial citrus crops from south of the border and attacks more than 40 different kinds of fruits. Damage occurs when the female fly lays eggs in the fruit, which then hatch into larvae, making the fruit unmarketable.

The fly is also a threat to surrounding citrus-producing states, including California, Arizona, Louisiana and Florida. Economic losses due to infestation not only are measured in damaged crops, but also in costs associated with eradication and shipping protocols aimed at consumer protection.

Primary eradication tactics include surveillance, bait sprays and Sterile Insect Techniques (SIT).
