Parasitoids of Anastrepha fraterculus and Ceratitis capitata in Argentina
Studies were carried out in the Tucumán* province on the parasitoids of Anastrepha fraterculus (EPPO A1 quarantine pests) and Ceratitis capitata (EPPO A2 quarantine pest) which are the two economically important fruit fly species in commercial fruit orchards in Argentina. Hymenopteran parasitoids were obtained from 5% of the tephritid puparia collected from 1991 to 1993, in urban and rural areas, from the ground below guava and peach trees. C. capitata was attacked by Pachycrepoideus vindemmiae (Pteromalidae) and Aganaspis pelleranoi (Eucoilidae). A. fraterculus was attacked by Doryctobracon areolatus (Braconidae) and A. pelleranoi. Although parasitism rates are low, the authors felt that further studies are necessary to determine the impact of these parasitoids on fruit fly populations.
* Tucumán province is a new detailed record for A. fraterculus.
