How did the bought bee eggs hatch?

Bees can be divided into four stages: eggs, larvae, pupae and adults.

The embryo in the egg develops and larvae hatch after 3 days. The larva stage of queen bee is 5 days, worker bee is 6 days and drone is 7 days. When the number of days arrives, the worker bees seal the nest with wax and pupate 2 days later. The pupal period of queen bee is 8 days, worker bee is 12 days, and drone is 14 days.

Bees are composed of queen bees, drones and worker bees, in which queen bees and worker bees are developed from fertilized eggs, while drones are developed from unfertilized eggs. The queen bee and worker bee are diploid (2n=32), and the drone is haploid (n= 16).

Growth and reproduction

Virgin queen bees (females) will keep their sperm in their bodies for several years after mating with drones. The queen bee can choose fertilized eggs or unfertilized eggs. The queen bee gives birth to unfertilized eggs in the drone room and develops into a drone (parthenogenesis). The queen bee produces fertilized eggs in the worker bee house and the queen bee house, and develops into worker bees and queen bees.

All bee larvae were fed with royal jelly for the first 3 days, and worker and drone larvae were fed with honey and pollen after 3 days. Only the larvae in the queen bee's room have been fed with royal jelly and developed 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 chromosomes), not by sex chromosomes. Bees and ants have no sex chromosomes.

Both queen bees and worker bees are females, which are developed from fertilized eggs. Each somatic cell contains 32 chromosomes and two sets of chromosomes, which are diploid. The number of UAV individuals in the population is very small, which is developed from unfertilized eggs. Somatic cells contain 16 chromosomes, and one chromosome group is haploid.

Bees are completely abnormal insects, and all three types of bees have to go through four development stages: egg, larva, pupa and adult. The four stages of bees are different in morphology.

Egg: banana-shaped, milky white, with a slightly transparent egg membrane, with a slightly thinner end as the abdomen end and a slightly thicker end as the head end. Among the eggs laid by the queen bee, the thinner end is the nest bottom, and the thicker end faces the nest mouth. The embryo in the egg develops and larvae hatch after 3 days.

Larvae: white worm. It started out as a C-shape. When the worm grows up, it straightens up with its head facing the nest. In the larval stage, it is fed by worker bees. Female larvae hatched from fertilized eggs will develop into worker bees if they are fed with larval pulp containing honey and pollen in royal jelly for the first three days. The same female larvae will develop into queen bees if they are fed with royal jelly continuously in the larval stage.

When the worker bee larvae grow to the end of the sixth day, the worker bee seals the nest mouth with a wax cover. The larvae in the covered nest room spin silk to make cocoons and then pupate. Larvae and pupa of Gai are collectively called Gai, and most of the nest spleen of Gai is called Gai spleen (pupa spleen).

The cover of worker bee pupa is slightly prominent, and the whole cover spleen looks flat. The cover of the drone pupa is convex and the nest room is large, so it is easy to distinguish the two. Worker bee larvae pupate at the end of 2 days after sealing.

Pupa: Pupa stage is mainly to transform and differentiate internal organs to form various organs of bees. The head, chest and abdomen are gradually presented, and the appendages are also exposed, and the color gradually darkens from milky white. Mature pupae, take off their pupa shells, bite through the nest cover and emerge into adult bees.

Adult bees: bees that have just left home have soft exoskeletons, soft hairs on their body surfaces and light colors. Soon the bones hardened, the four wings straightened, and the organs in the body gradually matured.
