What is the growth process of a silkworm baby, the growth process of a silkworm baby

The growth process of silkworm babies is divided into four stages: 1. Hatching; 2. Growth; 3. cocooning; 4. Adults.

1. Hatching: The silkworm baby is hatched from the egg, the silkworm egg is similar to the white sesame seed at first, and when it slowly turns black, the silkworm baby will drill out of the egg shell, and the newborn silkworm baby is black, like a small ant, so it is also called the ant silkworm.

2. Growth: After the ant silkworm begins to eat mulberry leaves, its body will slowly turn white, and after four times of peeling, it will grow into a fifth-instar larvae, at which time the silkworm baby will find a suitable position and begin to spin silk.

3. Cocooning: After the silkworm baby begins to spin silk, it generally takes two days to make the silkworm cocoon and transform into a silkworm chrysalis in the cocoon.

4. Adult: about 10 days or so, the silkworm pupae will break out of the cocoon, feather into an adult, and complete mating in a short time, and gradually die after laying fertilized eggs.

The growth process of silkworm baby is divided into four stages: silkworm eggs, larvae, cocoons, and adults, the silkworm eggs are transparent in the early stage, black in the later stage, and the newly hatched larvae are black, feeding on tender mulberry leaves, and the larvae become white in the later stage, feeding on old mulberry leaves, and the fifth-instar larvae will spin silk cocoons, and after ten days of breaking the cocoon, they become adults.

1. Silkworm eggs

The first stage of growth of baby silkworms is silkworm eggs. The silkworm eggs are round, the particles are small, and the newly laid silkworm eggs are transparent, at this time, the silkworm eggs are wrapped in a paper towel, and after waiting for a while, the silkworm eggs will turn black and the larvae will hatch.

2. Larvae

The second stage of growth of baby silkworms is the larvae. The newly hatched larvae are black and have fine hairs all over their bodies, and they need to be provided with fresh mulberry leaves to supplement their nutrition, and after a week, the baby silkworms will turn white and begin to peel. A larva has to molt a total of four times before it can reach maturity.

3. cocooning;

The third stage of silkworm growth is cocooning. The silkworm babies that have been shed four times belong to the fifth instar larvae, and the larvae at this time have the ability to spin silk and make cocoons, and will climb to the corner of the breeding box or the artificially provided area to spin silk and wrap themselves in it.

4. Adults.

The fourth stage of growth of baby silkworms is adulthood. After the cocoon is made, wait for ten days, the silkworm pupae in the cocoon will break out of the cocoon and become an adult, at this time it is necessary to cover the top of the container with a net cover to avoid the adult flying away, and after waiting for a day, the adult will mate on its own, so as to produce silkworm eggs and wait for death.

The growth process of silkworms will go through hatching, growth, silking, cocooning, and cocoon breaking. Silkworms reproduce by eggs, which resemble fine-grained sesame seeds, about 1 mm wide and about mm thick. After 7-15 days, when the eggs become transparent and the outline inside can be seen, it means that the baby silkworm is about to come out.

Silkworms that have just hatched from their eggs are covered with fine hairs and are also known as ant silkworms.

Silkworms live on mulberry leaves, and after eating mulberry leaves, their bodies turn white, and after a period of time, they begin to peel off. After a peel, it is a second-instar larvae. Even if you shed your skin once, you will have to shed your skin four times in total, and only when you become a fifth-instar larva will you begin to spin silk and form cocoons.

When the back of the silkworm is shiny and yellow, it means that it is going to spin silk and form a cocoon. It takes two days to form a full cocoon and complete the last molt in the cocoon, becoming a pupae. After about 10 days, it emerges as a silkworm moth and emerges from its cocoon. 

The life of a silkworm baby goes through four stages of development: silkworm eggs, larvae, silkworm pupa, and silkworm moths.

The growth of silkworms is generally 8-9 days in the incubation period, about 25 days in the larval stage, 14 days and 18 days in the pupal stage, and 3 days and 5 days in the silkworm moth period.

The first stage of the growth of the baby silkworm is the silkworm egg, which is round and transparent when it is laid, and the silkworm egg will turn black after a period of time. The newly hatched larvae are black, the whole body has fine hair, at this time it needs to provide it with fresh mulberry leaves to supplement its nutrition, the third stage is the cocoon, at this time there is the ability to spin silk cocoon, the fourth stage of the silkworm baby is the adult, the cocoon is made to wait for ten days, the silkworm pupae will break out of the cocoon.

Precautions for silkworm raising

Silkworm is a very cold creature, so when raising silkworms, we should pay attention to the temperature of breeding, usually in April and May of each year is the best time to raise silkworms, the temperature at this time is basically about 20 to 25 degrees, we do not need to spend a lot of effort to adjust the temperature of the breeding room, so later through the adjustment of temperature, there are also slowly other seasons of silkworm raising.

When raising silkworms and potatoes, it is necessary to pay attention to the mulberry leaves are best fresh, if the mulberry leaves are not fresh for too long, the silkworms will have diarrhea or do not eat after eating, and the second thing to pay attention to is that the mulberry leaves must be cleaned, there can be no dust, and at the same time, the silkworms can not be fed with dew or mulberry leaves that have not dried after cleaning.
