Mexican Fruit Fly

Mexican Fruit Fly

The Mexican fruit fly is a threat to many of our fruits. Don't move non-inspected fruit and vegetables.

The Mexican Fruit Fly (Anastrepha ludens) is a serious pest to various fruits, particularly citrus and mango. Mexican fruit fly was first found in Central Mexico in 1863, and by the early 1950s flies were found along the California-Mexico border. The pest has since been detected in Arizona, California and Texas. A large number of commercially grown crops, including avocado, grapefruit, orange, peach and pear, would be threatened if the Mexican fruit fly became established.

  • The Mexican fruit fly is not currently known to be in the U.S.

More than 50 host plants are at risk. The host list includes:

  • Apricot
  • Avocado
  • Citrus, except sour lime
  • Coffee
  • Guava
  • Most lemons
  • Mango
  • Nectarine
  • Orange
  • Passion fruit
  • Peach
  • Pear
  • Persimmon
  • Plum
  • Pomegranate
Fresh produce, fruit and vegetables brought into the U.S. or across state borders without inspection.
  • Visible adult flies: larger than a house fly, the body is a pale orange-yellow with two to three whitish stripes along the thorax. The wings are clear with several yellow and brown stripes. The female is distinguished by a long and slender ovipositor, which is used to deposit eggs beneath the skin of the host fruit.
  • Visible larvae within host fruit: legless, white to yellowish-white, and grows to a length of 0.4 (or 2/5) inches
  • If you have citrus trees in your yard, pick your fruit and use it, or double bag it and put it in the trash. Don’t leave fruit on the tree or on the ground.
  • Do not bring or mail fresh fruits, vegetables, plants into your state or another state unless agricultural inspectors have cleared them first.
  • Never remove fresh produce from your property if your area is under Mexican fruit fly quarantine.
  • Cooperate with all quarantine restrictions or rules that might be imposed.
  • Allow authorized agricultural workers access to property to install and inspect insect-monitoring traps.
  • Know the quarantines in your area and learn to leave Hungry Pests behind
