Lauri, just curious but why do you use vinegar, and ascorbic acid, and citric acid in the syrup? I don't feed much but I do use apple cider vinegar to adjust the pH.
I don't use the cider vinegar simply as a acidifier, it has amino acids, electrolytes and other nutritional benifets. The ascorbic and citric acids are for vitamin additions and to invert the sugar.
Here is input from JW Chestnut explaining the chemical reaction:
A primary reason for acidifying syrup is to "invert" the sugar. Cane sugar is pure sucrose. Sucrose is a 12 carbon sugar made up of two loosely joined six carbon sub-molecules (fructose and glucose). The acid disassociates the sucrose into the component parts, mimicking the nectar. This is termed by kitchen chemists "invert" sugar, and was used for baking. Most nectars (not all) are slightly fructose rich. The pH of nectar varies widely too (and many nectars, not co evolved with honey bees, have large components of indigestible (by bees) seven and greater carbon sugars. Practically, the sucrose sugar syrup can be inverted with vinegar or any other edible acid, and very little hydrogen ion donors are needed on the order of tablespoon per gallon. Ascorbic acid is made up of glucose (6 C sugar ring) with 2 carbon "tail" and various OH groups tagged to balance the Carbon charge. Many animals and their gut flora can synthesize this from any 6 carbon sugar source. A good reason to use at least some ascorbic acid (or tartaric) in the place of some of the simpler acids is ascorbic is a ring structure, while acetic (vinegar) is a simple unbranched chain. The ring is stable and "recycles" Hydrogen OH groups from solution. This means it is continually recovering donor potential and a little bit can invert an enormous solution much like a catalyst in reaction.
By using all three acids I am feeding a more diverse and possibly more complete mix.
It's the recipe I've used for 3 years
They like it and they do well. I have never fed Fumagillin and have never had case of Nosema.
Overwintered 133 colonies this year and came out with 128..but in
acutality I did not lose any colonies. I just lost a hand full of queens sometime early spring and caught the queenless colonies before they dwindled. They were combined with the overwintered queen in the mating nucs in February and March.
Can I attribute my healthy colonies to any one thing? Management? Feeding and nutritional recipies? Genetics? Location? Lack of exposures to commercial crops and other commercial beekeepers?
It's likely a combination of all of those things and other factors I haven't even realized.
Every year that goes by, however, I do give more credit to my genetics.
I've caught swarms near town that were likely from domestic hives and they have not done so well.
They usually go to town for a short time, then fizzled out by the fall without treatments. They were managed exactly the same as my existing hives.
The lack of disease resistance and lack of vigor is is so obvious I usually requeen any collected swarms unless I get them from remote areas.
