RABELO, L.R.S. et al. Fruit flies (Diptera, Tephritidae) in municipalities with a risk mitigation system for Anastrepha Grandis Macquart. Arq. Inst. Biol. [online]. 2013, vol.80, n.2, pp.223-227. ISSN 1808-1657.  http://dx.doi.org/10.1590/S1808-16572013000200012.

The objective of this study was verify the presence of A. grandis and identify other fruit-fly species collected in MacPhail traps, installed in areas of Cucurbitaceae under a risk mitigation system for Anastrepha grandis Macquart in the Vale do São Patrício Region, state of Goiás, Brazil, from November 2004 to October 2009. A total of 812 specimens of Anastrepha were captured, of which 639 were males (78.7%) and 173 were females (21.3%).  Fourteen species of Anastrepha were identified occurring in all seasons of the year. A. dissimilis Stone, A. quiinae Lima and A. pickeli Lima were recorded for the first time in the state of Goiás, and A. grandis and was recorded for the first time, with a low prevalence, in the municipalities of Jaraguá and Uruana, which belong to the risk mitigation system area, indicating good conditions for maintaining an area of low prevalence status. A. manihoti Lima (34.10%) was the most frequent species in the region, followed by A. obliqua (Macquart) (19.65%) and A. pickeli Lima (13.87%).
