Fruit flies are not native to Hawaii but were introduced to the islands. Over time, they have become a pest, affecting various fruits and vegetables. There are several species of fruit flies in Hawaii, including the Mediterranean fruit fly, the Oriental fruit fly, the melon fly, and the Malaysian fruit fly.
These flies lay their eggs in over 400 fruits and vegetables, leading to crop damage and loss.
The presence of fruit flies has economic implications for Hawaii, especially its export industry. Due to the risk of spreading these pests, many fruits and vegetables can only be exported from Hawaii to the mainland U.S. after undergoing specific treatments.
The state of Hawaii and the U.S. Department of Agriculture have implemented various programs to manage and control fruit fly populations. These include the release of sterile male flies to reduce breeding, using bait sprays, and public education campaigns to reduce the spread and impact of these pests.
Hawaiian Happy Face Spider
