Larvae of Fruit Flies. IV Dacus dorsalis (Oriental Fruit Fly)

The oriental fruit fly, Dacus dorsalis Hendel, originally described from Taiwan, is one of the most destructive fruit fly pests of east Asia and the Pacific, second only to the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). It ranges from Pakistan and India to southern Japan (Ryukyus), Indonesia to Micronesia and the Marianna Islands, and has been introduced into Hawaii. Recent outbreaks have occurred in southern California. Weems (1964) and Hardy (1969) summarized adult morphology and distribution ranges. The oriental fruit fly is known to attack over 150 kinds of fruits, being particularly destructive to mangoes, avocadoes, and papaya, as well as citrus.
