Abstract
1. In Western Burkina Faso, fruit flies (Diptera: Tephritidae) cause economic impacts.Damage on a mango can reach 100% in late varieties, and on shea fruits, the averageattack rate is 66.5%. Parasitoids offer natural biocontrol services, but the potential forthis in Burkina Faso remains unknown. 2. We performed a survey (2017–2019) in three plant formations (natural fallows n=6; agroforestry parks n=6 and mango orchards n=6) to determine the levels of parasitism of tephritid fruit fly pests. For this purpose, fruits from cultivated and wildfruit fly host plant species were sampled in these plant formations and incubated forinsects’ emergence. 3. In total, 1822 adults belonging to 7 parasitoid species were found. Fopius caudatus (Szépligeti) and Psyttalia concolor (Szépligeti) with 51.47% and 30.60% of the total of parasitoid adults emerged, respectively, were the most predominant. Parasitismrate varied according to host fruit species. Pupae recorded from Sarcocephalus latifolius and Vitellaria paradoxa were most parasitized (27.22%±3.96%) and (17.08%±2.37%), respectively, while those obtained from mangoes were the lessparasitized (3.73%±0.91%). 4. Mass rearing of F. caudatus and P. concolor, as well as habitat management, will contribute to the promotion of both, augmentation and conservation biological control.
