Abstract: As moscas-das-frutas (Diptera, Tephritidae) causam danos econ micos em muitas frutíferas. Para conhecer a flutua o populacional destas moscas em pomares de citros da regi o Oeste de Santa Catarina, Brasil, e estudar as interferências de fatores climáticos sobre estes insetos, cinco frascos "ca a-mosca", tendo vinagre de vinho tinto a 25% como atrativo, foram semanalmente instalados em dois pomares de laranjeiras da variedade Valência, em águas de Chapecó e Chapecó, no período de outubro de 1999 a setembro de 2001. As moscas capturadas nas armadilhas foram triadas no Laboratório de Fitossanidade da Epagri de Chapecó. Análises de correla o e regress o polinomial foram realizadas entre o número mensal de moscas do gênero Anastrepha e os dados mensais de precipita o pluviométrica, insola o, umidade relativa do ar, velocidade do vento e temperatura ambiente. Temperatura máxima e mínima mostraram interferir na popula o destas moscas mais do que os outros fatores climáticos. O número mensal acumulado de moscas capturadas foi submetido à análise de regress o n o linear, que revelou picos de captura destes insetos de mar o a junho. Anastrepha fraterculus (Wiedemann, 1830) predominou sobre outras espécies de moscas-das-frutas.

Abstract: As moscas-das-frutas Anastrepha fraterculus (Wiedemann, 1830), A. obliqua (Macquart, 1835), A. sororcula (Zucchi, 1979) e A. zenildae (Zucchi, 1979) foram submetidas a uma análise discriminante. Essas espécies do grupo fraterculus distinguem-se unicamente com base em detalhes do ápice do acúleo, que por serem muito semelhantes, dificultam a identifica o específica. A análise discriminante permitiu a separa o das quatro espécies de Anastrepha, com base em oito medidas do acúleo. Portanto, essa é mais uma técnica para auxiliar as identifica es de espécies de Anastrepha, como já acontece em muitos outros grupos de insetos.

Abstract: A mangueira (Mangifera indica L.) é a principal espécie frutífera da família Anacardiaceae cultivada no Brasil. A expans o dessa cultura nos últimos anos, tanto para o consumo in natura como para a exporta o, é limitada por diversas pragas, principalmente pelas moscas-das-frutas. No período de setembro de 1999 a fevereiro de 2000 foi estudado o nível de infesta o natural de moscas-das-frutas em dez variedades de manga, em três municípios do Estado de Goiás. Foram obtidos 1.195 pupários, dos quais emergiram 484 adultos de Anastrepha (80% dos insetos identificados), 104 lonqueídeos (17,2 %) e 17 braconídeos (2,8%). Das fêmeas identificadas, 77,9% pertenciam ao gênero Anastrepha e 22,08%, a Neosilba. As espécies identificadas foram: A. obliqua (48,78%), A. fraterculus (47,97%), A. sororcula (2,03%) e A. turpiniae (1,22%), referida pela primeira vez em frutos de manga no Estado. O parasitóide Doryctobracon areolatus foi encontrado em larvas/pupas de moscas-das-frutas, nas variedades Imperial e Tommy Atkins. As variedades com maiores índices de infesta o foram Imperial (15,3 pupários/fruto e 73,611 pupários/kg de frutos), em Goiania, e Tommy Atkins (7,0 pupários/fruto e 17,503 pupários/kg de frutos), no município de Orizona. Em Goiania, a variedade Bourbon n o foi infestada, e a Sabina apresentou um índice de infesta o de 0,076 pupários/fruto e 0,363 pupários/ kg de frutos. PALAVRAS-CHAVE: Insecta; Diptera; Tephritoidea; avalia o de danos; parasitóides. Mango (Mangifera indica L.) production has expanded greatly in Brazil but several pests, especially fruit flies, have limited both fresh fruit consumption and exports. Insect surveys are important in insect ecology, biology and control. From September 1999 to February 2000, ten mango varieties were surveyed for insects and level of natural fruit infestation in three counties of Goias. A total of 1195 pupae were obtained. Of the total adults, 80% were Anastrepha (484), 17.2% Lonchaeidae (104) and 2.8% Braconidae (17). Females belonging to Anastrepha genus and Neosilba genus represented 70.3% and 29.7%, respectively. Four Anastrepha species were identified: A. obliqua (48.78%), A. fraterculus (47.97%), A. sororcula (2.03%) and A. turpiniae (1.22%); the latter species reported for the first time attacking mangoes in Goiás. Doryctobracon areolatus was obtained from Imperial and Tommy Atkins mango varieties and was described for the first time attacking mangoes in Goiás. Imperial and Tommy Atkins were the most susceptible varieties with the highest infestation levels (15.3 pupae/fruit and 7.0 pupae/fruit, res
