Fruit flies in Hawaii are ubiquitous pests. They first arrived in the Hawaiian islands around 1895 and are widespread across all elevations and individual islands. At higher elevations they feed on plants both native and agricultural.
The most common types of fruit flies in Hawaii are the Melon fly, Mediterranean fruit fly, Oriental fruit fly, and the Solanaceous fruit fly.
Fruit flies are attracted to the yeast resulting from the beginning stages of organic material decomposing. The adult fruit fly will puncture the surface of organic material in order to feed and lay eggs.
Generally, the fruit fly is most active during warm, sunny days where they feed on plant secretions and aphid produced honeydew.
