I went and got 4 diff. kind of bees carni, russian,SMR and a northern breed Italian
just to try them all and do my own comparisions.
I had some robbing this fall even while feeding inside the hives
my thoughts on what may have been happening is the carni and the russians
both cut back on brood rearing in the fall for a smaller winter
cluster to conserve stores, but the Italians did not. So, I thought that
may make the carni and the russians more vounerable to robbing,
if they were all in the same yard that is.
Next year I am moving my Italians to another yard far from the rest.
from what I have read the russians came from carni stock a long time ago, and have become climatized to were they are found and
have been shown to have more resistance to v-mites.
Join a bee club and see what the locals prefer !
Thats my thoughts
