In my view, one of the most significant works on this topic:
> The study was timed to include the initial colonization of a large lowland biosphere reserve by feral Africanized honey bees. In the almost two-decade duration of our study (1988–2005), additional environmental factors such as drought and hurricanes were also considered. The study was divided into ‘pre’ and ‘post’-Apis periods. Immigrant Africanized honey bee swarms were first seen to arrive in 1989.

The ongoing Bee-L discussion is based on cherry picked confirmation biases.
