Insects; the integrating mechanism assuring that all members will be red is the appropriate food in the colony. The worker honey bee is a builder of honey-comb. In addition the worker receives nectar and pollen grain brought to the hive or carries debris and dead bees out of the hive, taking them off some distance and dropping them. A certain number of wax-secreting bees guard the entrance of the west, inspecting all incomers to be sure that they are boan of their colony.

When the colony becomes large the nurse bees set aside a few egge to be raised as queens, when the eggs pupate, the colony begins to split up. About half of the workers indubs the old queen to leave, and they fly off with her to begin a new colony. The other har rens ina. When the first new queen emerges, he may also be induced to leave with another group of workers if the colony becomes very Large again. Either she or the next queen, howM ever, remins as the new resident queen. As soon as one or the other is established the few other queens that may be hatching are destroyed

(a) The "social life" is described as human colony and those of some groups of insects such as ents, termites and honey bees.

In the colory of the honey bee, the queen bee is unable to organize a colony or to survive at all without workers. She appeara in an established colony, and flies out of the hive with male bees in chase on the nuptial flight. After that the queen is fertilized and returns to the hive to begin producing eggs. Most of the eggs develop into workers, and a in the other societies of some groups of

Egg atagu:

The eggs are laid by the queen bee, and are laid one by one in the cells where they have been cared very carefully. As in hatching, those laid in worker cells, develop into workers; in queen cells they develop into queens; while the unfertilized eggs laid in drone cells become the drones. All eggs are hatered within about three days, darval stage:

The larva of different types of bees is usually legless. The larva in its on cell is. fed by the worker with the appropriate food, The larval stage normally lasts for one week, during which the larva moults six tames and then upates.

Fupal state :

After about six times of moulting the larva is ready to pupate. Its cell is the capped with wax by the workers. The pupal stage can last for 4 to 5 days, then the capping is broken down and the imago emerges, Adult stage.

The adult bees are classified to three types, namely the queen (fertile female), the worker (sterile female) and the drone (sterile ble). They are all winged and are capable of flight, but differ in size.ky

⠀⠀⠀ The honey bees live in organized` communities and inhabit in a hive. The colony duties must be performed by the different individuals such as the queen, the worker 2nd the droney.

itions for this week;
