Abstract

Fruit flies are pests of economic importance in West Africa due to their quarantine status and losses recorded in fruits and vegetables. Before the introduction of exotic species of parasitoids against any exotic fruit fly species, it is fundamental to first determine the presence and monitor the native parasitoid species. This work was carried out in Casamance (Senegal), during the rainy season of 2010, with sampling of 5191 fruits from 22 plant species. Seven species of parasitoids (all Braconidae) were recorded and reared from six fruit species. The parasitoids included (Szépligeti), (Wharton), (Bridwell), (Silvestri), (Szépligeti), (Wilkinson) and (Szépligeti). The most abundant species was (63.97 %). The overall mean parasitism rate observed in all samples was 2.4 ± 1.3 %. (Walker) (77 %) was the host fly most commonly reared from fruits yielding parasitoids including Pers. was the fruit species most frequently infested by fruit flies and (Boj. ex DC) Pichon fruits had the highest parasitism rates. In the current work, there were no parasitoids reared from the recently introduced pest, Drew, Tsuruta and White. This is the first report of all these reared parasitoids, except , in Senegal.
