Since the invasion of the African continent by the oriental fruit fly, Batrocera dorsalis (Hendel) (syn. B. invadens [Drew, Tsuruta & White]), tephritid fruit flies have become a growing problem in the Democratic Republic of the Congo (DRC). Very few studies on these species have been conducted, and none in the South Kivu region. We carried out a preliminary survey of tephritids in the South Kivu which is part of the Albertine Rift zone. Both para-pheromone and food bait lures were used. Bactrocera dorsalis (70.6%) and Ceratitis fasciventris Bezzi (22.4%) were the most abundant species. We also recorded the species B. cucurbitae (Coquillett), Perilampsis curta Munro, C. anonae Graham, C. cosyra (Walker), C. punctata (Wiedemann), C. rosa Karsch, Carpophthoromyia vittata (Fabricius), Dacus (Leptoxyda) eminus Munro , D. bivittatus (Bigot), D. punctatifrons Karsch, D. (Lophodacus) hamatus Bezzi, D. (Dacus) hargreavesi Munro, and D.
(Leptoxyda) siliqualactis Munro. In addition, we observed the occurrence in the study area of a weaver ant, Oecophylla longinoda Latreille, a predacious ant known as a biological control agent in some African orchards. We present here the first record of B. dorsalis in fruit orchards in South Kivu, DRC, and suggest that Oecophylla longinoda could be used
as an important part of an IPM program for the control of fruit flies in orchards, and for reducing pesticide usage. The results also highlight future research avenues for improving fruit production in this area.
