Umbu-cajá as natural repository of native fruit fly parasitoids

The objective of this work was to assess the species diversity of fruit fly and their parasitoids in fruit of umbu-cajá (Spondias spp.). Fruit were collected in nine municipalities of the state of Bahia, Brazil. Fruit infestation, fruit fly parasitism rates, and frequencies of the parasitoid species were estimated. For the first time, Anastrepha obliqua infesting umbu-cajá fruit and the presence of the native parasitoid Asobara anastrephae in Anastrepha oblique larvae were recorded. The native parasitoid Doryctobracon areolatus was the most frequent. Umbu-cajá tree is a natural repository of Tephritidae parasitoids, and its preservation is essential for the maintenance of trophic relationships between fruit fly species and parasitoids.
