Scientists have figured out how bees actually make a queen

A new study shows: it's more complicated than that. The future queen develops not only thanks to special food. The bees build a special "nursery" for her - the maternity house - where the shape of the cell, wax composition, heat, humidity and the work of young bee-builders are all important.

The work is published in the journal Nature.

Simply put, bees don't just feed the larva "king food." They create an entire environment for her that helps her become a queen.

Details

Worker bees and future queens start out almost identical: they develop from similar fertilised eggs. But beyond that, their fates diverge dramatically. The worker bees stay smaller, live smaller lives and fulfil tasks in the hive. The queen grows larger, develops faster and becomes the main egg-laying female of the colony.

Previously, the main focus has been on royal jelly, a nutrient mixture that worker bees feed to the larvae of future queens. But the authors of the new work decided to check whether the very "room" where the larva grows plays a role.

This room is called the brood chamber. It differs from the usual hexagonal cells where worker bees develop. The nest box is larger, more elongated and resembles the shape of a peanut or a small cocoon.

Researchers have shown that it is not only the shape that distinguishes the uterus from the normal worker cells. The wax in them has different mechanical and chemical properties. The paper says that mother cells have special physicochemical features that are markedly different from those of worker bees.

This is important because the larva does not develop in a void. It is affected by everything around it: temperature, humidity, wax composition, chemical signals and the behaviour of the bees that care for it.

To test the role of the cell, scientists changed the conditions under which future mothers are reared. It turned out that the environment does affect development: the properties of the maternity cell are necessary for normal queen formation. Nature states this conclusion explicitly: the physicochemical signals of the uterus are causally necessary for normal development of the queen.

Another important finding concerns worker bees. The researchers identified a special group of young workers who build nest boxes. These bees don't just put wax in as they go. They create a special environment and at the same time change physiologically: their organism is rearranged for the task of building a queen cell.

It turns out that the future queen "makes" not only one factor. It is formed by the whole colony: forage, wax, cell shape, heat and the work of the bee builders.

Why it matters

This study changes an all too simple view of hive life. The royal jelly is indeed important, but it doesn't explain everything. The fate of a larva depends not only on what it is fed, but also on the environment around it.

For biology, this is an important example of how living organisms can literally build the conditions for other organisms to develop. In bees, the colony works as a single system: some bees build, others feed, others maintain the temperature, and all of this together affects what the larva will become.

There's a practical point, too. The quality of a bee's mate is important to the whole hive. If the mate develops poorly, the whole colony suffers: it reproduces less well, renews itself more weakly and can become less stable. Therefore, understanding exactly how healthy mates are formed is important for both science and beekeeping.

Background

The bee mate is not a "queen" in the human sense. She doesn't rule the hive with orders. Her main role is to lay eggs and ensure the continuation of the colony.

But a lot depends on her health. The uterus can live much longer than the worker bees and produce huge numbers of offspring. So the hive invests a lot of resources in raising her.

The popular scheme used to be simple: more royal jelly, you get a queen. New work shows that bees have a more subtle way of doing things. The royal jelly is not just a protective capsule. It's a specially designed "incubator" that helps guide larval development.
