The last 13 years have seen drastic reduction, but it certainly makes me contemplate if it is a situation where temporary conditions masked a long term phenomenon for 20 years or if we are simply witnessing a short term effect at present.
At least there is a division of labour among the different types of honey-bees in the colony or hive. The different forms or types of insects having a particular function live in the colony, called the castes. Thousands of bees 50, to 1,00, or more which live in a hive are of three different forms: So honey-bees are well known as social and polymorphic insects.
The true social organization eusociality of honey-bees is well understood in the study of Apis mellifera. Both queen and workers are female and diploid.
Drones are males and haploid.
A strong or healthy colony is called when the maximum number of workers is found in the colony. Generally a single matured queen is present in each hive. The size of the queen is nearly 2.
If is characterized by the long tapering abdomen, well-proportioned body, short and golden coloured wings and colour of the legs. The queen possesses a curved sting at the tip of the abdomen which is known as ovipositor.
The eggs may be either fertilized or unfertilized. Depending on the type of food supplied to the newly developed larvae by the nursing workers the eggs may develop either queen or workers. The queen deposits each egg in a cell prepared by the worker bees Fig.
After three days the eggs hatch into small larvae. The royal jelly is a high proteinous substance produced by the hypopharyngeal glands of the workers. The sting of the queen serves an ovipositor for lying of eggs and is also used for defence.
The sting is used only when she meets another rival queen. The Dutch naturalist Swammerdam remarked that queen is the mother of the entire colony and has no food collecting organs. When the queen becomes matured she leaves the hive with some drones and takes several nuptial flights and mates with a drone.
After copulation the drone dies soon after and the queen stores enough sperm in the spermatheca to last her lifetime.

The queen after copulation returns in her old hive and is looked after by nurse workers, known as her retinue. With the increase of the age the egg laying capacity of the queen loses, the workers choose a three day old egg.Detailed studies of populations that show significant differentiation in the number of matings may be able to discriminate effectively among the different hypotheses that have been proposed to explain the evolution of polyandry in honey bees and other advanced social insects.
