Document Summary
Saturated sugar solution produced by honey bees from plant nectar. Contains simple sugars that do not require additional digestion, as well as proteins (including enzymes), vitamins, minerals and water (no more than 20%) Nectar is collected and processed by bees to transform it into honey. Nectar contains 20-50% solids, rest of water. Most of the solids are sugars mainly sucrose (table sugar) In honey, most of the sugars are glucose and fructose. Foragers regurgitate the nectar and pass it to nectar receptors. Conversion of nectar into honey: by chemical and physical transformation. Nectar flow is the period when flowers are producing enough nectar for the bees to collect and store. Before this period, colonies are managed as follows: Swarm control: checking for queen cells between brood boxes until the nectar flow starts. 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 foundation frames)
