Abstract : Parasitoids are important natural control agents of tephritids and knowledge about the tritrophic relationships can support the management of these pests. This study aimed to estimate of parasitism indexes in fruit flies in 21 plant species and identify the species of parasitoids associated, in semiarid conditions of Southwestern Bahia. Eight hosts showed infestation by Anastrepha spp. and, of these, four occurred parasitism above 20.0%, of which: 20.8% (Ziziphus joazeiro L.); 21.3% (Spondias tuberosa L.); 32.4% (Spondias purpurea L.) and 57.1% (Malpighia emarginata L.). The collected parasitoids belong to the Braconidae family, 89% of Doryctobracon areolatus and 11% of Asobara anastrephae.
