Bees are of immeasurable value to our
environment. |
 |
Bees are pollinators vital to our food chain.
|
 |
Without bees one third of the food we eat would not be available. |
 |
Bees, like other insects, are part of a food chain. |
 |
The harvest from honeybees of honey, pollen, wax and propolis
(an antiseptic resinous substance obtained from some
trees) has nutritional, craft, manufacturing, and medical applications. |
 |
Pollination by bees is important for genetic sustainability.
|
 |
Bees are in danger of disappearing from our environment.
|
 |
Farming practices continue to disturb the natural habitats and forage of solitary
bumblebees at a rate which gives them little chance for re-establishment.
|
 |
The honeybee is under attack from the varroa mite and it is only the treatment and care provided by beekeepers that is keeping colonies alive.
|
 |
Most wild honeybee colonies have died out as a result of this disease.
|
 |
In Summer, a typical hive of honeybees might contain:-
 |
1 queen
250 drones
20,000 female foragers
40,000 female house-bees
5,000 to 7,000 eggs
7,000 to 11,000 larvae being fed
16,000 to 24,000 larvae developing into adults in sealed cells |
|
 |
Bees eat pollen to produce bee milk, often called royal jelly, which they feed continuously
to the queen and to larvae, for just 3 days, after they hatch from eggs. |
 |
Bees eat honey primarily to fuel their wing muscles. |
 |
To collect a pound of honey (half a kilo) a bee might have to fly a distance equivalent to twice round the world.
|
 |
This is likely to involve more than 10,000 flower visits on perhaps 500 foraging trips.
|
 |
A colony can use
32kg of pollen each year involving over 300,000 foraging trips. On each trip a bee could return with half a million grains of pollen.
|
 |
The pollen is used by the bees as their protein food for building bee body parts.
|
 |
To make 1 kg of wax, it is estimated that a bee must consume 4
kg of honey.
|
 |
They secrete wax scales from 4 pairs of glands under their abdomen, each wax scale weighing about 1 mg.
|
 |
It is estimated that about 80,000 wax scales are necessary to make a single
honeycomb. |
