All fruit flies are very small insects that lay their eggs in various plant tissues.
Drosophila melanogaster, also called vinegar fly, is a much used laboratory insect; its 10-day life cycle and large chromosomes, particularly those of the salivary glands of the larva, have made it invaluable in the study of genetics.
Fruit flies are classified in the phylum Arthropoda, class Insecta, order Diptera, families Tephritidae and Drosophilidae.

The larvae (maggots) of the olive fruit fly feed inside the fruit, destroying the pulp and allowing the entry of secondary bacteria and fungi that rot the fruit and impair quality or flavor of the oil.
Olive fruit flies may be distinguished from related fruit flies by the presence of fl spots on the wing tips and the lack of banding across the wings that occurs in most other related species such as the walnut husk fly, apple maggot, and Mediterranean fruit fly.
In areas where the olive fruit fly is not well established, adult olive fruit fly populations are being monitored with yellow sticky traps containing a sex pheromone (spiroketal) and/or ammonium carbonate, ammonium bicarbonate, or diammonium phosphate bait.
