The one-year total sum of recorded species showed that there were 12 fruit fly species per site, except in Sakété with 11 fruit fly species. However, the weekly mean of fruit fly species richness was the highest in Allada while the lowest was recorded in Sakété, although the difference was not significant(P 0.05) (Table 3). Moreover, the mean values of Shannon diversity, Simpson diversity, and Shannon evenness were also not The Shannon evenness or equitability values obtained in the current study were low(les than 0.4) indicating that the weekly species equitability is low, which is obvious since at all the studied sites, B. invadens alone accounted for more than 88 of the total number of recorded species(Table 2)
