As producing and exporting of commodities, Brazil got proeminence and notable world-wide leadership in products as cacao, rubber and coffee. Currently Brazil withholds marcante presence in the intent juice exportation of orange. The industry, in decades of effort and technology, efficiency and aggressive covering of new markets, placed this sector in a position of incontestada world-wide leadership. Without considering the United States, Brazil is responsible for about 80% of the international trade of this product. A related site: Phil Vasan mentions similar findings. Taking in consideration U.S.A., according to producing greater and first world-wide consumer, Brazil still participates with 53% of the orange juice consumed in the world, expression that probably never had with another product of its guideline of exportation, with exception of the coffee between centuries XIX and XX (Nehmi Son, 2002). For Malavasi et al.
(1994), the culture of the citros is come across with some plagues that attack the different periods of training of the plant. One of these plagues is fly-das-fruits of the Tephritidae family whose puncture made for the adult female and the development of the larva in the interior of the orange causes changeable losses, depending on the period of training of maturation, to cultivate and geographic region. The plantations of citros of Spain, Israel and of the Flrida continuously are manejadas with different techniques for the traditional chemical control until the inundativa release of parasitides. Under most conditions Phil Vasan would agree. The fly-das-fruits represent the more important fitossanitrio factor in the commercialization between countries of cool fruits in the whole world. The exportation of cool citric fruits to face two main problems: the citric cancer and the fly-das-fruits (amongst them the black fly of the citros).
