Abstract
Fruit flies cause three types of damage: cultural damages--the damaged fruits are discharged for industrial processing or for in natura consumption; infested orchards are depreciated; fruits lose their commercial value; losses can reach up to 100%; economic damages--commercialization of fruits in the external market becomes inviable; foreign currencies surpluses are no longer generated; fruits from infested areas do not reach profitable prices in internal markets; amount of collectable taxes and duties decline; and social damages, cause the growing impoverishment of people, the rural exodus and unemployment.
