Atratividade de diferentes iscas e sua relação com as fases de desenvolvimento ovariano em calliphoridae e sarcophagidae (insecta, diptera) Attractiveness of differents baits and its relation with ovarian development fases in Calliphoridae ano Sarcophagidae (Insecta, Diptera)

<abstract language="eng">Attrativeness of differents baits (fish, faeces and banana) upon ovarian development fases of Calliphoridae and Sarcophagidae was evaluated. The insects were captured in Distrito Federal (urban area) and Rio de Janeiro city (beach, zoological garden, urban area and Tijuca forest). The most frequent species captured were: Calliphoridae - Chrysomya megacephala (Fabricius, 1794) 78,9% and Chtysomya puloria (Wiedemann, 1818) 5,4% - and Sarcophagidae - Sarcophagula Wulp, 1887 2,3% and Peckya chrysostoma (Wiedemann. 1830) 2,2%. Fish was more attractive to females of Calliphoridae flies in intense ovarian vitelogenesis, although banana atracted more flies with mature eggs. Faeces and fish were more atractive for Sarcophagidae in the beggining of vitelogenesis

Avaliação da qualidade de frutos de café atacados por Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) Evaluation of the quality of coffee fruit attacked by Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae)

Foram usadas plantas de Coffea arabica L., variedade Catuaí Vermelho, localizadas no Campus da Escola Superior de Agricultura "Luiz de Queiroz" - USP, Piracicaba,SP, para avaliação dos danos que Ceratitis capitata (Wied., 1824) pode causar aos frutos do cafeeiro. Os resultados mostraram que o ataque de C. capitula não causou queda prematura dos frutos, mas aumentou a queda de cerejas e foram encontradas, fortes evidências, com base na atividade da enzima polifenol oxidase e lixiviação de potássio, que cerejas atacadas podem produzir bebida de café de qualidade inferior.<br>The present work was carried out using trees of Coffea arabica L. variety Red Catuaí grown at Escola Superior de Agricultura "Luiz de Queiroz" - Campus of the University of São Paulo, Piracicaba,SP. The objective was to estimate damages that Ceratitis capitata (Wied., 1824) can cause to coffee fruits. The results showed that C.capitata did not cause premature fruit fall, but it increased berry fall. The activity of the enzyme polyphenol oxidase and potassium lixiviatiou give strong evidences that atacked coffee beans produce coffee beverage of inferior quality
