Hello Barry & All,
I thank Barry for the excellent post. Although not a expert on AHB and not
on a AHB experience level with Barry I am going to ask a few questions and
make a few comments.

I had my doubts until I read and reread the work of Dr. Kerr. I believe Dr.
Kerr was always trying to correct the problems his release caused. He will
go down in my opinion as one of the most talented bee researchers in
history.

I believe we are on *the same page*. You with the actual *hands on
experence* and me with reading every article about AHb I could get my hands
on. Please correct me if I am not correct as I am trying to learn from you.

Are you talking about a classification other than the 12 African races
described by Ruttner (1975)
Scuts are "yellow" bees and capensis "black."
What are the color of your ApiCrown queens?

Does the Cape bee worker carry similar pheremones to a scut queen? A
European queen?
. Of course, capensis is famous in the bee world for being the only race in

I have read the above is true but if queens are raised from fertile eggs how
does the Cape bee produce a fertile egg without mating? From laying workers
we know all mellifera can lay eggs but not fertile. We also know any
fertilized egg if cared for and fed properly can be made into a queen. Are
Cape bee workers feeding larger amounts of Royal jelly to their brood to
make the egg laying area different than the other races. Even so how are
the eggs made fertile?
Could it not be possible for cape bees to have higher developed reproduction
areas similar to a queen and actually breed with drones. Has this theory
ever been explored? I always look for the simple answer first.

What is their color ? Is the color still a sign of the pure scut as it was
when Lepeletier (1836) named them?

These are the A. mellifera s. my fellow beekeeper have seen on trips to
Brazil and Mexico. Dr. Kerr was able to completely remove all aggression
from the scut by instrumental insemination and inbreeding. The fear was
always that once open mating was allowed the aggression would return.

I would say the statement is true of all bees but I am sure many on the
list are going to disagree with us both.

Again the above is true with all bees except for the killing part with other
races. All bees in hive so defence goes up.

I find it curious they have survived the test of time? I also wonder why the
Cape bee brought into Brazil by Dr. Kerr did not survive in its pure state?

I believe this is simply because of the higher pheromone level. I see the
above behavior by workers with young queen more so than older queens. I
asked the question at a bee breeders meeting once if higher levels of
pheromones was a trait bee breeders bred for. The answer was no because the
average production queen was replaced before pheromone levels normally
dropped in the U.S. The answer was most queens produce a enough pheromones
to keep from being superceded for up to three years. My friend Murray from
Scotland reports many queens laying into and through the third year. All his
queens are marked.

Do your open mating areas consist of drone colonies of hives headed by I I
queens similar to the breeder queens?

Dr. Kerr said the bad traits of scuts could be bred out but mainly by
inbreding and I I. You have taken longer but if I am understanding you
correctly you have eliminated the bad traits by selection only. Or selection
and inbreeding?

Barry you *almost* make me want to order a few queens. My bees don't always
behave. Surely you see a supercedure with a attitude once in a while?
Be honest!
The "best of" capensis is pretty much limited to a single

Dr. kerr could have isolated this gene and put the trait in another bee. His
research might prove helpful. Steve Tabor is a walking encyclopedia of Dr.
Kerr's work and I believe would talk to you if contacted. Dr. Kerr and Steve
were friends besides doing similar research. My friend and fellow beekeeper
which worked with Steve at Bato Rouge in 1967 said Dr.Kerr's work was Steve
Tabor's favorite subject.

In my opinion pure scuts in the U.S. will be rare indeed.
The current ApiCrown breeder queens have 18

How much of the eighteen generations is inbreeding back to drones from the
same hive?

These ApiCrown queens sound better than my bees.
Thanks for the post Barry!

Ps. Dietz (1986) published a potential distribution map of AHb in the U.S..
I disagreed at the time (as did others) and disagree today. My reasons then
were the same as Barry's about the AHb distribution in Africa. The map can
be found on page 46 of the new *Hive and Honey Bee* and many other
publications. Tooting my horn fifteen years later!
