The knowledge about species composition of fruit fly in the Mid-Western Region of Brazil is scarce. The aim of this paper is to evaluate the population dynamics of fruit fly species in a mixed orchard with 21 fruit tree species (22º 13 16 S e 54º 48 20 W) in the campus at Federal University of Grande Dourados (UFGD), Dourados-MS. The survey was carried out during two consecutive years of sampling (May 2005 to June 2007). A total of 14 McPhail traps, baited with the Bio Anastrepha® food attractant, were hung up in the branches of 14 fruit tree species. Some 11,775 fruit flies adults were caught belonging to eight genera: Anastrepha Schiner (1868), Ceratitis MacLeay (1868), Hexachaeta Loew (1873), Tomoplagia Coquillett (1910) and Blepharoneura Loew (1873) (Tephritidae); Dasiops Rondani (1856), Lonchaea Fallén (1820) and Neosilba McAlpine (1962) (Lonchaeidae). The result shows that the hosts with higherinfestations by fruit flies in the orchard, were: starfruit (Averrhoa carambola L.) and guava (Psidium guajava L.), with the infestation indexes (larvae/kg) of 101.60 and 41.12, respectively. A. obliqua was the predominant species, in both, traps and fruits / Na região Centro-Oeste do Brasil são escassos os trabalhos de pesquisa sobre a composição de espécies de moscas-das-frutas. O objetivo deste trabalho foi avaliar a dinâmica populacional das espécies de moscas-das-frutas em um pomar no Centro-Oeste brasileiro (Universidade Federal da Grande Dourados - UFGD, Dourados-MS). Em quatorze armadilhas McPhail (iscadas com a atrativo alimentar Bio Anastrepha®) foram capturados 11.775 indivíduos em dois anos de coletas (maio de 2005 a junho de 2007). As espécies identificadas pertencem a oito gêneros: Anastrepha Schiner (1868), Ceratitis MacLeay (1868), Hexachaeta Loew (1873), Tomoplagia Coquillett (1910) e Blepharoneura Loew (1873) (Tephritidae) e Dasiops Rondani (1856), Lonchaea Fallén (1820) e Neosilba McAlpine (1962) (Lonchaeidae). Os resultados obtidos indicam que os hospedeiros mais infestados por moscas-das-frutas no pomar da UFGD, foram: carambola (Averrhoa carambola L.) e goiaba (Psidium guajava L.), com índices de infestação (larvas/kg) de 101,60 e 41,12, respectivamente. A. obliqua foi a espécie predominante, tanto nas armadilhas quanto nos frutos
