Yes I am feeding 1-1 sugar syrup, the Italians have took about 1gal of syrup and the Russian have took about 2gal of syrup. I have watched them every day the Italians fly earlier than the Russians but the Russians are better workers (faster in and out of the hive and more traffic) they are bring in a lot more pollen than the Italians
The Russians will build up faster than the Italians. The pollen count you've noticed per hive is a proof of it. It takes a lot of pollen as well as honey to produce a good amount of bees. Russians are geared for shorter foraging opportunities and have learned that more bees can produce more honey so they build up quickly in the spring, often swarm my mid-April, even in colder climates, and then shut down in mid-late August and go into survival mode, topping of stores and reducing brood production.
Italians on the other hand build up at a steady pace through June, then begin gradually drop back. They put as much effort into stores early on as they do brood production. During the Spring an Italian hive will probably have more honey stores than the Russians do.
But at the end of summer the Russians have produced as much, if not more, honey as the Italians, have a smaller group of bees going into cluster and just as much in the way of stores. In the spring the Russians will have a smaller cluster and likely twice as much honey stores left from which to begin brood development than the Italians.
