The Invasion of the Dwarf Honeybee, , along the River Nile in Sudan.

The spread of the dwarf honeybee, , 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 and native along the river Nile. The invasive had significantly higher population densities than the wild, native . Nevertheless, we found no indication of competitive displacement, suggesting that although had a high invasive potential, it coexisted with the native along the river Nile. The genetic data indicated that the invasion of was established by a single colony.
