Document Summary

Sugar solution produced by honeybees from plant nectar. Nectar is collected and processed (chemically and physically) by bees to transform it into honey. Nectar contains 20-50% solids, the rest is water. Foragers visit 100s of flowers to secure a load. Trophallaxis foragers regurgitate the nectar and pass it to nectar receptors. Invertase breaks sucrose into glucose and fructose. They blow bubbles and expose the bubbles of nectar to the warm currents of air in the hive also produce warm air currents by beating their wings. Swarm control checking for queen cells between brood boxes until the nectar starts to ow. New white wax at the top of the frames tell us when to add more supers. Top or bottom supering (depends on having or not having foundation frames) Top supering in the supers, the comb has been built in every area.
