Moscas frugívoras (Diptera: Tephritoidea) associadas ao umbu-cajá (Spondias sp.) no Recôncavo Baiano

Abstract

This work had as objective to obtain information on the species of flies frugívoras and its parasitóides associated to the “umbu-cajazeira” (Spondias sp.) in the Recôncavo Baiano region, State of the Bahia, Brazil. 49 samples of the fruits were collected among the months of March to July of 2002 with a total of 4,095 fruits and 74.45 mass (Kg); of these fruits was obtained 30,579 pupae, with emergency index of 37.39% of tefritídeos (11,435 adults). The largest frequency was of Anastrepha obliqua (99.59%), proceeded by A. fraterculus (0.24%) and A. sororcula (0.17%). The infestation index was of 410.73 pupae for kilogram of fruits and 7.47 pupae for fruit. Three species of parasitoids of the family Braconidae were identified, and the largest relative frequency was of Doryctobracon areolatus (94.10% of the emerged parasitoids), followed by Utetes anastrephae (1.08%) and Asobara anastrephae (4.82%). The viability pupal and the total parasitism were, 62.85% and 40.50%, respectively. The fly Neosilba zadolicha McAlpine & Steyskal (Diptera: Lonchaeidae) is reported for the first time in “umbu-cajazeira” fruits (Spondias sp.), in the Recôncavo Baiano region.
