ABSTRACT

Doryctobracon maculatus Marinho, a new species of Braconidae (Opiinae) collected in the municipalities of Piracicaba and São Roque, state of São Paulo, Brazil, is described and illustrated. This new species is placed in group of species with areolate propodeum, but is easily distinguished from other species of this group, and other members of the genus by the noticeable black to dark-brown spots on the head, mesosoma and metasoma. This new species was reared in larvae of Anastrepha pseudoparallela (Diptera, Tephritidae) in passion fruits, Passiflora alata Curtis (Passifloraceae). An illustrated key to species of Doryctobracon recorded in Brazil is presented.

ABSTRACT

Este trabalho teve como objetivo conhecer os índices de infestação natural, o percentual de emergência dos adultos e as espécies de moscas-das-frutas associadas ao umbu-cajá (Spondias sp.) no Recôncavo Baiano. Foram coletadas 49 amostras dos frutos entre os meses de março a julho de 2002, totalizando 4.095 frutos (74,4 kg), dos quais obtiveram-se 30.579 pupários, com emergência de 37,4 por cento de tefritídeos. Anastrepha obliqua (Macquart) (99,59 por cento) foi a espécie dominante, seguida por A. fraterculus (Wied.) (0,24 por cento) e A. sororcula Zucchi (0,17 por cento). O índice de infestação foi de 410,7 pupários por quilograma de frutos e 7,5 pupários por fruto.


The objective of this work was to quantify the natural infestation, pupal survival and fruit fly species associated to fruits of Spondias sp. in the Recôncavo Baiano, State of Bahia, Brazil. From March to July, 2002, 49 samples of fruits were collected with the total of 4,095 fruits and a biomass of 74.4kg. About 30,579 fruit fly puparia were obtained from which 37.4% yielded adults. Anastrepha obliqua (Macquart) (99.6%) was the dominant species, followed by A. fraterculus (Wied.) (0.24%) and A. sororcula Zucchi (0.17%). The infestation index was 410,7 pupae for kilogram of fruits and 7.5 pupae per fruit.
