Abstract
The spread of the dwarf honeybee, Apis florea, in Sudan along the river Nile in a linear fashion provides a good model for studying the population dynamics and genetic effects of an invasion by a honeybee species. We use microsatellite DNA analyses to assess the population structure of both invasive A. florea and native Apis mellifera along the river Nile. The invasive A. florea had significantly higher population densities than the wild, native A. mellifera. Nevertheless, we found no indication of competitive displacement, suggesting that although A. florea had a high invasive potential, it coexisted with the native A. mellifera along the river Nile. The genetic data indicated that the invasion of A. florea was established by a single colony.
