OTHER HIVE PRODUCTS
Ernesto Guzman
Part of the information can be obtained from the textbook, as well as from lectures
I will emphasize the following:
BEESWAX
- Hydrocarbon secretion of bees’ abdominal glands.
● Density = 0.95
● Hydrocarbon product used by bees as a building material
- Properties. It is lighter than water (density = 0.95) with a melting point of 62º C
● Insoluble in water
● Cappings are melted
○ The wax layer floats to the top and can be removed, the lower part
contains honey
● Solar wax melter
○ Leave with a glass lid and then wax cappings melt under the sun and flow
downwards to be collected
- Obtained by melting cappings (from honey extraction) in a mold.
- Uses of beeswax.
● Wax foundation
● Candle industry (can use molds to create different figures, or simply dip and cool)
● Cosmetic industry (creams, ointments, lotions, and lipsticks)
● Polishes
● Insulator
● Dental impression wax
POLLEN
- Male reproductive cells of flowering plants.
● Not produced in the hive, produced in flower, but considered as a hive product
● Supplies nutrients for brood rearing and adult bee growth
● Varies in composition (protein major component) depending on the source
collected from (about 23% protein content)
- Pollen is collected with traps placed at the bottom of hives.
● Replaces the screen bottom board
● Bees need to go across the traps to get into the hive
● Foragers must pass through the trap as they return to the hive (pollen pellets
scraped off by hardware cloth)
