D7,
I asked Darryl Patton et al about this over in Jeff Randall's forum, as they is VERY experienced with killer bees in S.A. and as beekeepers. This is a link to that thread, with many replies starting:

Here's Darryl's answer from that thread:
Don't get too worked up over killer bees. While dangerous, they have been blown out of proportion. They are simply a more aggressive version and that is it. In the South, the wild "black" bees (a variation of course of the Italian) can be just about as mean.
Bees vary from hive to hive with some having worse temperaments than others. When one stings you, the pheromones from the venom alert the others and they will in turn cover you up whether they are killer bees or not. The safest thing is to avoid them or to get the hell out of the area if you come into contact. Killer bees being so much more aggressive don't give up the fight as easily as regular bees. Their sting and venom is no worse. They just tend to sting more.
While in the military in Hawaii, I took up beekeeping as a hobby and had about 200 hives next to the runway at Hickam airfield. Hawaii has had Killer Bees there since the 1960's when somebody imported them due to their hardworking ethic. They tend to pack in more honey into a hive. When I worked my bees I had to keep their aggressive nature in mind. Hives with good Italian queens meant I could work them in a t-shirt, shorts and no veil. If I worked a hive with Killer Bees, I had to completely suit up as they would cover me so bad I sometimes could not see through the veil easily. It took a lot of smoke to control them and I don't want to think of the number of stings I would still get at times.
Just remember, around any honeybee, wear light clothes not dark, no soaps, perfumes etc. These tend to set them off like crazy. Other than that, if you have a nasty run in with them, run like crazy out of the area and head for water.
The further North they go, the milder in temperament they become. There is still a lot of debate as to how much cold weather they can stand due to their tropical origins.
Take Care,
