Bee's Behavior

How quickly do bees multiply? Reproduction of Honey Bees

To maintain bee populations for our needs and deliver their role of pollination, they have to reproduce in large numbers.  Like the other insects, their life span is short. They must have a way of creating young bees, and quite often.  The colony population greatly depends on the queen’s ability to lay eggs. 

 A honey bee colony has a single queen, thousands of workers, and a few hundred drones. The queen is usually the mother of all bees in the hive. She usually mates once with 10-12 drones and stocks sperms in her body ( 5 to six million sperm cells) to fertilise eggs destined to be worker bees. Unfertilised eggs result in drones.

Do All Bees Have a Reproductive System?

Not all bees can have babies. Most of the bees you see buzzing around, like worker bees, are female, but they can’t have babies. They’re busy gathering food and taking care of the hive instead. Only one bee, the queen, can have babies. She’s the big boss bee in the hive, and her job is to lay eggs. Male bees, called drones, also have reproductive parts, but they don’t do much except mate with the queen. So, while not every bee can make babies, having a queen bee with a reproductive system is super important for the colony’s survival.

What Is the Atrophic Reproductive System?

The atrophic reproductive system is when the female worker bees in a hive have underdeveloped or inactive reproductive organs. This means they can’t lay eggs like the queen bee does. Instead, they focus on their jobs like collecting food and taking care of baby bees. Having this system helps the hive run smoothly because it means each bee has its own role without worrying about making babies. So, even though they’re all female bees, most of them can’t reproduce, leaving that job to the queen bee.

How Does the Queen Bee Decide Whether to Fertilize the Egg?

The queen bee is pretty amazing! She can choose whether to fertilize her eggs or not, deciding if they’ll become worker bees or drones. When she mates with male bees, she stores their sperm in her body. Then, when she lays eggs, she picks which ones to fertilize based on the size of the cells in the hive. If the cell is big, she usually fertilizes the egg, and it becomes a worker bee. But if it’s a smaller cell, she might leave it unfertilized, and it grows into a male drone. This way, she keeps the right balance of worker bees and drones in the hive.

How quickly do bees multiply?

Like other insects, honey bees have four distinct life stages. The developmental stages vary with a bee caste. Drones take 24 days to mature, workers take  21 days, and the queen takes 16 days. Each takes four developmental stages, starting with the egg, larva, and pupa and ending with an adult. An egg hatch after three days, but the days they take to reach adulthood differ. Surprisingly, the queen (biggest of all) takes less time to reach adulthood, although she feeds on a special diet.  

The life span of the bees also differs, with the queen living for years. After the queen lay eggs, worker bees( nurse bees) takes up the duty of nurturing them until they become adults. All larvae are put on a special diet known as royal jelly in the first three days of their lives. Those destined to be queens are fed with the diet throughout their larval stage. Royal jelly is a protein-rich substance secreted by young worker bees from their hypopharyngeal glands on the head.

Do bees reproduce in all seasons?

In late fall, there is a reduction of nectar and pollen sources. Due to the minimal food resources coming to the hive, the colony reduces brood rearing to reduce the population. This is also the time when drones are kicked out of the colony to preserve the winter food reserves as much as possible. The bees form a tight cluster in winter with the queen at the centre. 

The queen’s egg-laying stops completely at this time as the bees concentrate on keeping warm. The queen begins to lay eggs in late winter to aid in replacing the bees that have died during the cold season.  Early brood rearing depends on pollen stores gathered in the fall. However, egg-laying and brood-rearing in tropical and subtropical regions usually never stop. In spring, new sources of pollen and nectar help to stimulate brood rearing. The population increases steadily in spring.

Bees also Reproduce at a Colony Level

The bees prepare to swarm when the colony grows large and crowded, especially in late spring and summer.  The old queen and half of the bee population leave to form a new bee colony in a new nest. Swarming is a natural process of how a colony reproduces as a whole. This happens when the weather is conducive and abundant food resources are available.  To avoid losses through swarming, beekeepers split or divide their colonies into two. However, they must check the signals in a colony to know when to know then the bees are preparing to swarm.
