What Makes Winter Honey Bee's so Special?

Have you ever wondered why winter bees live longer?

The Answer: Vitellogenin.

Next question; what is Vitellogenin?

Vitellogenin is classified as a glycolipoprotein as it has properties of sugar, fat and protein. The honey bee colony's health is dependent upon the buildup of this protein reserve as it acts as an antioxidant to prolong the Queen and forager's lifespan. It is also used to produce royal jelly and is a vital part of the bee's immune system. Additionally, it functions as a hormone that affects future foraging behavior. Within the worker bees, those with the highest levels of Vitellogenin are given the job of nesting bees while those with exhausted reserves become foragers.

How does this impact my winter bees?

We always recommend feeding bee's sugar syrup with a supplement going into the winter. This is a no-brainer. What we don't touch upon is the protein intake of a colony. The best indicator of adequate protein is the diversity of pollen stores. Colonies that are still rearing brood can easily deplete their pollen stores and begin to delve into their Vitellogenin during a pollen dearth. The upcoming winter generation needs to have built up lipids and proteins stored in their fat bodies (nutrients held in the bees body) so that they may survive without honey stores. Keep in mind that high levels of vitellogenin going into winter will help with the pollen shortage in early spring.

There are many advantages to feeding syrup and protein sources in the fall. There are several nutritional supplements that can be included in syrup to incorporate the needed nutrients to maintain a healthy colony.

  • Honey B Healthy us used in spring and winter to stimulate the immune system
  • Amino B Booster is a blend of free amino acids that assimilates directly through the mid gut to the bees' hemolymph and hemocytes, then transported to the sites where protein is needed for bee growth.
  • Vitamin B Healthy provides the needed nutrients vital for bee health when pollen sources are scarce or pollen lacks the essential nutrients.
  • Hive Alive strengthens the bees' immune system and helps bees absorb the nutrients, proteins and sugars needed to increase brood production.

Beekeepers with negligible fall pollen should look to pollen sources to sustain or build up protein reserves. The best pollen source would be that extracted from the colony or from a reputable local supplier, however, there are other substitutes that will provided the needed protein and lipids.
  • You need to look to sources with protein levels higher than 25% such as our Ener-G-Plus which provides this with approximately 32% crude protein.
  • Save time with the prepared pollen substitute in patty form.
Honey bees require protein, carbohydrates, lipids, vitamins, minerals and water. Ensure the emerging generation going into winter has an abundant, nutritional diet so they may pack in their fat bodies for longer months.
