Как из обычного пчелиного яйца всего за 16 дней появляется матка?

How can two virtually identical eggs, laid by the same queen in the same colony, develop into completely different bees? One produces a worker bee. She cleans the cells, feeds the brood, guards the entrance, brings nectar, and can live only a few weeks during the active season. The other egg produces a queen bee, capable of living for several years and laying up to two thousand eggs per day. There is no special "queen egg." At the beginning of development, the genetic makeup of the future worker bee and the future queen is almost identical. The difference arises later, when the colony selects a young larva and begins feeding it in a special way. In this video, we'll take a detailed look at the sixteen days of queen development—from a normal egg to the moment the young queen emerges from the sealed queen cell. 00:00 — Two Identical Eggs, Two Different Fates First, we'll compare a worker bee and a queen. Why does one bee live a short life and perform dozens of difficult tasks, while another can live for several years and become the only full-fledged breeder in the entire colony? 00:55 — Does the queen lay special eggs? The queen doesn't select a special egg destined to become the new queen. She lays a regular fertilized egg. The future fate of the future bee is determined after the larva hatches. 01:45 — Who makes decisions inside the hive? Bees don't hold meetings or vote. However, the colony responds to chemical signals, the age of the brood, and the presence of the queen. Nurse bees select a suitable young larva and begin rebuilding its cell. 02:35 — Why does the future queen literally swim in food? All young larvae initially receive royal jelly. But the future queen is fed much more generously. The bees fill the queen cell with so much royal jelly that the larva literally floats in the white, nutritious mass. 03:30 — How does the worker larva's diet differ? After a few days, the worker larva begins to receive a different mixture, containing more honey and pollen components. The future queen continues to be constantly supplied with large quantities of royal jelly. 04:15 — What changes does royal jelly? Royal jelly contains proteins, sugars, fatty acids, and other active substances. It influences growth rate, hormonal processes, ovarian development, body size, and the future queen's ability to reproduce. 05:00 — Epigenetics in simple terms The larva's DNA is not replaced or transformed. What changes is which parts of this DNA remain active. It can be compared to the same book being read differently. The worker bee skips some chapters, while the future queen opens additional pages. 05:55 — A Precise Calendar of Queen Development The egg remains in the cell for the first three days. Then a small larva emerges and begins to be intensively fed. It rapidly grows in size, and the bees continue to draw the queen cell downward. 06:45 — What happens after the queen cell is sealed? When the larva finishes feeding, the bees seal the queen cell with a wax cap. Pupation and a complete reorganization of the queen's body begin inside. The wings, eyes, legs, internal organs, and the long abdomen of the queen are formed. 07:30 — Why does the queen develop faster than a worker bee? It takes about sixteen days for the queen to develop. A worker bee needs about twenty-one days, and a drone about twenty-four. This speed is especially important when the colony suddenly loses its old queen. 08:10 — How do bees know that the queen is gone? After the loss of the queen, her pheromone levels decrease. Worker bees sense the change in chemical balance and begin to behave differently. If the colony contains suitable young larvae, the bees begin building emergency queen cells. 08:55 — Why can't any larva be made into a queen? The ability to alter development remains only during early development. If a larva is already too mature, it will not be able to become a full-fledged queen. Therefore, a colony without fresh eggs and young larvae can find itself in a critical situation. 09:30 — It's not the queen that creates the colony, but the colony that creates the queen A queen is essential for the colony's survival, but it is the worker bees who select the larva, build the queen cell, control feeding, temperature, and the entire developmental schedule. A young queen is the result of the collective work of the entire colony.
