Doug,
I don't know for sure,but the africanized bees are the same species as european bees. Those out of africa were better honey producers,but more aggresive. If I had to guess,I'de say they were a little less suceptable,just because of their long history of coming from a harsher enviroment. I don't hear of them having the trouble with mites and stuff that commercial bees do. But remember,most hives in the US are destroyed as soon as found. In most of south america,and all of central america,including all of Mexico,africanized bees are the commercial bees.
