The Mediterranean fruit fly (Ceratitis capitata or Medfly) is considered the one of the most damaging agricultural pests in the world. It can infest a wide range of fruits, nuts, and vegetables, including apples, avocados, bell peppers, melons, and tomatoes. The damage makes crops inedible and unmarketable.

The Medfly has spread throughout the Mediterranean region, Southern Europe, the Middle East, Western Australia, South and Central America, and Hawaii. The first of numerous U.S. mainland infestations occurred in Florida in 1929.

  • Appearance
    • Medfly eggs are white, very small, and elongated.
    • Larvae (maggots) are legless and white and feed inside the fruit.
    • Adult Medflies are smaller than a house fly. They have a blackish thorax marked with silver, a tan abdomen with darker stripes, and clear wings with light brown bands and gray flecks.
  • Damage
    • Fruit decays early and falls to the ground as the larvae develop and feed on the pulp.
