Parasitoids associated with fruit flies (Diptera: Tephritoidea) in organic coffee plantation under shaded and unshaded management in Valenca, RJ, Brazil

The aim of this work was to determine the parasitoid species associated with fruit flies infesting six cultivars of arabic coffee under shaded and unshaded organic management. A 1kg-sample of maturing fruits per cultivar was harvested in May 2005. The fruits were placed in plastic trays containing a layer of thin sand, as a substrate for pupa phase. The puparia were quantified and kept in transparent plastic cups with sand until the emergence of the insects. Seven parasitoid species of the order Hymenoptera were identified, from which five belong to the family Braconidae: Asobara anastrephae (Muesebeck), Doryctobracon areolatus (Szepligeti), Utetes anastrephae (Viereck), Opius bellus Gahan and Opius sp., and two of the Figitidae: Aganaspis pelleranoi (Brethes) and Lopheucoila anastrephae Weld. Larvae of Tephritidae and Lonchaeidae infesting fruits of the six cultivars were parasitized by Braconidae and Figitidae, with an average of 14.2% and 7.7% in the unshaded and shaded systems, respectively.
