If B. invadens in Africa is synonymous to B. dorsalis thus they are one and the same:- therefore management practices applied for B. dorsalis can be applied to B. invadens in Africa.
You need to refer to the following article which you can request for directly from the authors.

After the synonymization (Schutze et al. 2015), B. invadens should be quoted as B. dorsalis, as in theory,B. invadens are no longer existed- they were 'misidentified' as B. invadensinitially based on slight differences in the morphology. In fact, in the case of B. papayae, we (Malaysian fruit fly group working on tephritid fruit fly) already 'synonymized' B. papayae as B. dorsalis, as far back as in 2005, based on the evidence in identifical pheromone system. The synonymization of B. papayae, B. philippinensis and B. invadens into B. dorsalis, although came a bit late (almost 10 years later) just proved that we cannot based on morphological basis alone in taxonomical studies.
