Description
Summary:ABSTRACT We studied the diversity and level of infestation of fruit flies in mango orchards in a semi -arid region in the state of Minas Gerais, Brazil. Surveys were conducted in orchards in the irrigated perimeter of Jaíba municipality in northern Minas Gerais, from November 2016 to November 2017. Sampling was conducted by collecting mangoes and trapping flies in McPhail traps. Of the total adult flies obtained (9,033), 8,902 specimens were Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), making it the predominant species collected in the traps (91.3%). ‘Palmer’ mango fruits were only infested with C. capitata, and showed high infestation rates (15.14 puparia kg-1 of fruit). The population peak of C. capitata coincided with the occurrence of mature mango fruits in the orchards. C. capitata was the most frequent and constant species identified in the survey and can be considered a dominant species. RESUMO Estudou-se a diversidade e infestação de moscas-das-frutas em manga na região semiárida do estado de Minas Gerais. Os levantamentos foram realizados em pomares localizados no perímetro de irrigação no município de Jaíba, no norte de Minas Gerais, no período de novembro de 2016 a novembro de 2017. A amostragem foi realizada por coleta de frutos e com armadilhas McPhail. Do total de adultos obtidos (9.033), 8.902 espécimes foram Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), coletados predominantemente em armadilhas (91,3%). Frutos de manga 'Palmer' foram infestados apenas por C. capitata, com altas taxas de infestação (15,14 pupários.kg-1 de fruto). A população de C. capitata coincidiu com a ocorrência de frutos maduros de manga nos pomares. C. capitata é a espécie mais frequente e constante da pesquisa, sendo considerada uma espécie dominante.
