Document Summary
Unit ten other products and benefits from bees. Used as building material in the hive (bees draw comb and cap cells). It is lighter than water (density = 0. 95) with a melting point of 62 c. beeswax is obtained by melting cappings (from honey extraction) in a mold. When the cappings cool off, the wax layer floats on the water and can be removed. Beeswax is used for comb foundation, in the elaboration of candles, in cosmetics (creams, ointments, lotions and lipsticks), polishes, dental impression wax, varnishes and as insulation material in electronic products. Bees use it as a source of nutrients (proteins, lipids and vitamins) for brood rearing and to feed newly-emerged adult bees. Pollen is collected with traps placed at the bottom of hives. Pollen traps have a hardware cloth through which returning worker foragers must pass and while doing that, pollen pellets are scraped off their legs by the hardware cloth.
