I did a Google search and found the following:
Apis mellifera cecropia (The “Greek” bee)
Very similar in appearance to the Italian bee, the Greek bee is favoured for its very mild temperament, large colony size, lack of tendency to swarm and good foraging ability. However it is renowned for being a heavy producer of propolis, making it difficult to separate hive parts and is not thought to do well in the damp and cooler climates of northern Europe. The Greek bee has often been used to produce crosses in an attempt to instil less aggression into northern bees. However, some beekeepers have reported that crosses of Greek and Northern strains often produce very aggressive colonies one or two generations on.
I don't know whether Greeks use these commercially but they are the native bees.
