Hi All

Whatever the true meaning of the word 'feral' is,
Mike's explanation below seems about right to me, my course in a similar
circumstance would have been selection, which can show good results in five
years and even better in 7+ years.

I am a person that selects strongly for supersedure, but I am doing it with
a race of bees that exhibits the behaviour strongly as part of it's make up
and has a mating frequency that matches the tendency, (is much higher than
the Italian types that are prevalent in US).

If you start to select for supersedure and do not get a corresponding
increase in mating frequency, you will run the risk of a degree of
inbreeding that you can only overcome by deliberately introducing extra
genes into the closed system that forms the next part of your post...

So to use a phrase that I often use 'horses for courses' I would suggest
that you will either run into inbreeding problems or inadvertently select
for genes of a racial type that you have been trying to eliminate (amm).

Any isolated mating system needs to have large numbers of colonies and wide
diversity within it's sphere of influence. This is hardest to achieve with
Italian bees, because they exhibit the lowest mating frequency of all races
and thus require a larger number of colonies within the system.
