Fruit flies (Diptera, Tephritidae) in the Goiás State, Brazil: occurrence and distribution

The Goiás State, in Brazil, presents a high number of host plant species for fruit flies, whose fruits ripen at different seasons, providing an increase in the pest population density and its wide distribution. Throughout the Goiás State, fruit flies occur in high or low frequency, both in rural and urban areas. Besides the Mediterranean fruit fly (Ceratitis capitata), 21 species of Anastrepha flies are currently known, mainly A. obliqua, A. fraterculus, A. sororcula and A. zenildae, due to their economic importance, and A. grandis, for being a quarantine pest. The A. grandis species has been recorded in 13 cities in the Goiás State, however, this information does not preclude the fruits export programs implemented in the State, because it was observed, in the production units, that the FTD index (flies trap-1 day-1) was lower than 0.1, in accordance with the rates established by the Brazilian legislation, for the export of cucurbit fruits.
