1) There is only one problem. The syrup fed is normally sucrose which the bees invert into simple sugars fructose and glucose,
2) If they are fed too late, it can in effect convert long lived winter bees into shorter lived summer bees. This can cause a colony to die out in February or March.
3) If feeding can be done prior to the winter bee brood cycle, it can be successful.
If they were true, I would not have any bees.
1) before sucrose goes into bees blood circulation, the molecule is splitted to glucose and fructose. Same happens in your belly.
2) water content of food turns winter bee to summer bee. That will never happen.
3) I mostly feed the colonies when the most winterbees have emerged
Pollen in wintering hive:
Xx) last bees emerge during feeding. Feeding starts brood rearing again, and they make perhaps 2 brood frames. When those bees emerge, they needs lots of pollen to finish their growing to wintering bees. They need pollen to that.
Same way, when colony has one box of brood, when I start to feed them, I put extra empty box over the brood, that they can store the winter food into empty box. That colony needs quite much pollen.
If bees do not have pollen, they eate the larvae off to their protein needs.
In my climate I have 8 wintering months when bees do not get pollen from nature. When I start pollen patty feeding in April, I can see how big need of protein bees have. It is huge, without that they even have eggs in the hive.
But perhaps bees need different theories to get over the winter. They are flexible animals and they stand many kind of beekeeping.
Same bees but different wintering theories
