Apiculture or bee-keeping is the rearing and management of honeybees for obtaining honey and beeswax.
Honey bees are of great economic importance because they yield valuable products like honey and beeswax.
Honey is made from the nectar that the honeybees collect from the flowers. It is an aromatic sweet syrup that contains water, sugars (dextrose and levulose), minerals and vitamins.
Due to high nutritive value, honey has a lot of medicinal importance.
Beeswax is secreted by the wax glands located in the abdominal segments of worker bees (sterile females). Beeswax mainly consists of esters of fatty acids and various long chain alcohols. It is widely used for making cosmetics, creams, ointments, paints and polishes.
Honeybees collect pollen and nectar from different flowers. In doing so, they also pollinate the flowers. Hence, they act as agents of pollination and help in the transfer of pollen grains from the anther of one flower to the stigma of another flower on the same plant or different plant. Keeping beehives in or near fields during the flowering season of crop plants increases cross-pollination and crop yield.
Lac is not produced by honeybees. It is a scarlet-coloured resinous secretion of a small insect known as Laccifer lacca. It is used as a sealing wax and stiffening agent.
