Hist. Nat. Univ. Caldas [online]. 2017, vol.21, n.2, pp.81-98. ISSN 0123-3068.  https://doi.org/10.17151/bccm.2017.21.2.6.

The objective of this work was to contribute to the knowledge of the diversity of fruit flies (Diptera: Tephritidae) and their natural enemies in the department of Nariño. A total of 14,005 fruits from 16 host plant species were collected, belonging to ten botanical families (Rubiaceae, Rosaceae, Myrtaceae, Fabaceae, Anacardiaceae, Rutaceae, Cucurbitaceae, Annonaceae, Solanaceae and Caricaceae), all of which showed infestation by fruit flies or parasitoids, except for the Annonaceae family.The species of fruit flies collected in this study were Anastrepha fraterculus complex, Anastrepha striata, Anastrepha obliqua, Ceratitis capitata and Anastrepha grandis species known for their polyphagia and great adaptability. A total of 242 individuals belonging to seven species of parasitoids, DoryctoBracon crawfordi, DoryctoBracon zeteki, Utetes Anastrephae, Microcrasis sp., Bracon sp., Torymus sp., and Ichneumonidae sp.1 were obtained. Parasitoids were collected from nine plant hosts corresponding to coffee, guava, loquat, hobo, guava, orange, mango, peach and guama. The highest frequency of parasitoids occurrence was presented in DoryctoBracon crawfordi, with values of 84.1, 76.7 and 40% in coffee, guava and hobo respectively. Utetes Anastrephae was 5.7% in coffee and 6.0% in hobo. Parasitism was also present in Rubiaceae, Rosaceae, Myrtaceae, Fabaceae, Anacardiaceae and Rutaceae.
