CATDOLL : CATDOLL: How many stages does it take for a bee to grow from egg laying to adulthood, and how many days does each stage last?

The process of bee development from egg laying to adulthood is divided into four stages: egg, larva, pupa and adult.

The embryo inside the egg develops into a larva after 3 days.

The larval stage of queen bees is 5 days, that of worker bees is 6 days, and that of drones is 7 days. When the number of days is up, the worker bees will seal the entrance of their nest cells with wax caps, and they will pupate 2 days after the capping.

The pupal period of a queen bee is 8 days, that of a worker bee is 12 days, and that of a drone is 14 days.

Bee breeding:

After mating with a drone, a virgin queen bee (female) will store sperm in her body for several years. The queen bee can freely choose to lay fertilized eggs or unfertilized eggs. The queen bee lays unfertilized eggs in the drone cell and develops into a drone (parthenogenesis). The queen bee lays fertilized eggs in the worker cell and queen cell and develops into a worker bee and queen bee.

All bee larvae are fed royal jelly for the first three days, and worker bee and drone larvae are fed honey and pollen after three days. Only the larvae in the queen bee cell are always fed royal jelly and fully develop into queen bees.

The sex of an organism is not necessarily determined by sex chromosomes. In bees and ants, sex is determined by the number of chromosomes (or the number of chromosome sets), not sex chromosomes. Bees and ants do not have sex chromosomes. Queen bees and worker bees are both female, and they develop from fertilized eggs. Each somatic cell contains 32 chromosomes, two chromosome sets, and are diploid. Drones are very few in number in a colony, and they develop from unfertilized eggs. Their somatic cells contain 16 chromosomes, one chromosome set, and are haploid.

Bees are composed of queen bees, drones and worker bees. The queen bees and worker bees develop from fertilized eggs, while drones develop from unfertilized eggs. The queen bees and worker bees are diploid (2n=32), while drones are haploid (n=16). How do haploid drones produce sperm? In the process of producing sperm, the spermatocytes of drones undergo a special form of meiosis. In the first meiotic division, the number of chromosomes does not change, but the cytoplasm is divided into two parts of different sizes. The large part contains a complete nucleus, and the small part is just a mass of cytoplasm, which will degenerate and disappear after a period of time.

The second meiotic division is an ordinary mitosis: in the mass of cytoplasm containing the nucleus, the chromatids separate from each other, and the cytoplasm undergoes unequal division. The part with more cytoplasm (containing 16 chromosomes) further develops into sperm, while the part with less cytoplasm (also containing 16 chromosomes) gradually degenerates. Through this meiosis, a spermatocyte of a drone produces only one sperm, and both spermatocytes and sperm are haploid cells. This special meiosis is called "pseudomeiosis."

The life cycle of bees from laying eggs to becoming adult bees is divided into: Bees are holometabolous insects and go through four stages in their life: egg, larva, pupa and adult.

The embryo inside the egg develops into a larva after 3 days. The larval period of the queen bee is 5 days, that of the worker bee is 6 days, and that of the drone bee is 7 days. When the number of days is up, the worker bees will seal the entrance of the nest cell with wax, and the larvae will pupate at the end of 2 days after the capping. The pupal period of the queen bee is 8 days, that of the worker bee is 12 days, and that of the drone bee is 14 days.

Honey bees are composed of queen bees, drone bees and worker bees. The queen bee and worker bees develop from fertilized eggs, while drone bees develop from unfertilized eggs. The queen bee and worker bees are diploid (2n=32), while drone bees are haploid (n=16).

Growth and reproduction

After mating with a drone, a virgin queen bee (female) will store sperm in her body for several years. The queen bee can freely choose to lay fertilized eggs or unfertilized eggs. The queen bee lays unfertilized eggs in the drone cell and develops into a drone (parthenogenesis). The queen bee lays fertilized eggs in the worker cell and queen cell and develops into a worker bee and queen bee.

All bee larvae are fed royal jelly for the first three days, and worker bee and drone larvae are fed honey and pollen after three days. Only the larvae in the queen bee cell are always fed royal jelly and fully develop into queen bees.

The sex of an organism is not necessarily determined by sex chromosomes. In bees and ants, sex is determined by the number of chromosomes (or the number of chromosome groups), not sex chromosomes. Bees and ants do not have sex chromosomes.

Both the queen bee and the worker bee are female, and develop from fertilized eggs. Each of their somatic cells contains 32 chromosomes, two chromosome sets, and is diploid. There are very few drone bees in the colony, and they develop from unfertilized eggs. Each of their somatic cells contains 16 chromosomes, one chromosome set, and is haploid.

Honey bees are insects that undergo complete metamorphosis. All three types of bees go through four stages of development: egg, larva, pupa and adult (adult bee). The four stages of honey bees are morphologically different.

Egg: Banana-shaped, milky white, with a slightly transparent egg membrane. The thinner end is the end of the abdomen, and the thicker end is the head. The thinner end of the egg laid by the queen bee is at the bottom of the nest cell, and the thicker end is toward the nest cell mouth. The embryo in the egg develops and hatches into a larva after 3 days.

Larvae: White worm-like. Initially C-shaped, as the larvae grow, they straighten and their heads face the cells. They are fed by worker bees during the larval stage. Female larvae hatched from fertilized eggs will develop into worker bees if they are fed larval jelly with honey and pollen added to royal jelly for the first three days. The same female larvae will develop into queen bees if they are fed a large amount of royal jelly continuously during the larval stage.

When the larvae grow to the end of the sixth day, the worker bees will seal the mouth of the cell with wax caps. The larvae in the capped cells spin silk cocoons and then pupate. The capped larvae and pupae are collectively called capped cells, and the honeycomb with most of the caps is called a capped honeycomb (pupa honeycomb).

The cap of the worker bee pupa is slightly protruding, and the entire capped comb looks relatively flat. The cap of the drone bee pupa is convex, and the nest cells are larger, so the two are easy to distinguish. The worker bee larvae pupate at the end of 2 days after the cap is sealed.

Pupa: The pupal stage is mainly to transform and differentiate the internal organs to form the various organs of the adult bee. Gradually, the head, thorax and abdomen appear, and the appendages also appear. The color gradually changes from milky white to darker. The mature pupa sheds the pupa shell, bites through the nest cell cover, and emerges as an adult bee.

Adult bees: The exoskeleton of newly emerged bees is relatively soft, the hairs on the body are very tender, and the body color is relatively light. Soon the skeleton hardens, the four wings straighten, and the various organs in the body gradually mature.

There are four stages: egg, larva, pupa and adult.

The eggs hatch into larvae after 3 days.

The larval stage of worker bees is 6 days, the capping stage is 12 days, and the final stage is 21 days.

The larval stage of the male is 7 days, the capping stage is 14 days, and it takes a total of 24 days to emerge from the cell.

The queen bee's larval stage is 5 days, the capping stage is 8 days, and it takes a total of 16 days to emerge from the hive.

Additional information:

Bees are social, living in groups, metamorphosis (eggs, larvae, pupae, adults), and are composed of three types of bees (worker bees, queen bees, and drones). They live in beehives and feed on pollen and nectar. The queen bee is the mother of the family, and the worker bees (honey bees) and drones are the children of the queen bee. It is a typical matriarchal society.

Taxonomic evolution

According to fossil data, bees have been found in large numbers in the late Eocene strata of the Tertiary Period. Their appearance is closely related to the prosperity of flowering plants in the late Cretaceous period.

In terms of classification, the superfamily Apoidea is close to the superfamily Sphaeroidea, and its ancestors may have originated from a branch of the superfamily Sphaeroidea. However, due to different feeding habits, the morphological characteristics also tend to diverge. The evolutionary characteristics of honey bees are: chewing and sucking mouthparts, the formation of pollen-collecting organs, and branching of body hairs; both adults and larvae eat nectar and pollen; the emergence of group and social lifestyles; the emergence of polymorphism and parasitism within the superfamily, etc.

In the class Insecta, bees belong to a highly evolved group. They have developed a social lifestyle, the transmission of "language" information, the method of identifying beehives through "dance" movements, and the different structures of nests.

The worker bee's egg stage is 3 days, the larvae are 6 days, the capping is 12 days, and it takes a total of 21 days to emerge from the hive.

Bees are social, living in groups, metamorphosis (eggs, larvae, pupae, adults), and are composed of three types of bees (worker bees, queen bees, and drones). They live in beehives and feed on pollen and nectar. The queen bee is the mother of the family, and the worker bees (honey bees) and drones are the children of the queen bee. It is a typical matriarchal society.

Bees lay eggs in the hive chamber, and the larvae live in the hive chamber. The larvae that lead a social life are fed by worker bees, while the larvae that lead a solitary life eat the bee food stored in the hive chamber by the female bees. When the bee food is eaten up, the larvae mature and pupate, and then emerge from the cocoon when they emerge from the cocoon. Domesticated bees breed several generations a year, while wild bees breed 1 to 3 generations a year. They overwinter as mature larvae, pupae or adults. Generally, males appear earlier than females, have a shorter lifespan, and do not take on the tasks of building nests, storing bee food and raising offspring. Female bees build nests, collect pollen and nectar, and store them in the hive chamber, and have a longer lifespan than males.

In the bee society, they still live a matriarchal life. Bees go through four metamorphosis stages in their life: eggs, larvae, pupae, and adults. Among the members of their large family, there is a queen bee, a female bee with reproductive capacity, who is responsible for laying eggs and reproducing offspring, and at the same time "ruling" the large family. Although the queen bee has mated, not all of the eggs she lays are fertilized. According to the needs of the large family, it can lay fertilized eggs, which the worker bees feed with pollen and honey, and then develop into female bees (worker bees without reproductive capacity) after 21 days; it can also lay unfertilized eggs, which develop into drones after 24 days. When the members of this large family reproduce too much and cause crowding, the group must be divided. The process of swarming is as follows: worker bees build special honeycombs - queen cells, in which the queen bee lays fertilized eggs; after the larvae hatch, the worker bees give them special treatment, feeding them with the highly nutritious royal jelly they produce in their bodies. After 16 days, when the larvae develop into adults, they become new queen bees with reproductive capacity, and the old queen bee leads a group of worker bees to fly away and form a new swarm. Chinese honey bees Apis cerana Fabr. and Italian honey bees A. mellifera L. are both commonly raised beneficial insects. During the breeding process, after the new queen bee is born, it must be manually swarmed, otherwise a queen bee will lead a group of worker bees to leave the hive and fly away, resulting in a loss of productivity of the bee colony.
