CATDOLL : CATDOLL: The specific process of silkworm rearing (What is the specific process of silkworm rearing)

1. What is the whole process of silkworm rearing?

There are five stages in silkworm rearing: silkworm eggs - larvae - mature silkworms - silk cocoons - silk moths, which takes a total of more than forty days.

Ant silkworm: When the silkworm hatches from the egg, its body is brown or reddish brown, very small, and has many fine hairs, which looks a bit like an ant, so it is called an ant silkworm. The ant silkworm is about 2 mm long and 0.5 mm wide. After it crawls out of the egg shell, it will eat mulberry leaves after 2 to 3 hours.

The sleeping nature of silkworms: Silkworms eat a lot of mulberry, so they grow very fast and their body color gradually fades. But their appetite gradually decreases or even completely stops eating. They spit out a small amount of silk, fix their abdomen and feet on the silkworm seat, raise their head and chest, and stop moving, as if they are asleep. This is called "sleeping". The sleeping silkworms may seem motionless on the outside, but they are preparing to shed their skin inside. After shedding the old skin, the silkworms enter a new age. From ant silkworms to spinning silk cocoons, they shed their skin four times in total. Having the sleep nature is one of the growth characteristics of silkworms. Sleep nature is a genetic trait of silkworms and is also affected by the environment. The silkworms currently raised in my country belong to the four-sleeping varieties.

Silkworm age: also known as age period, which indicates the development stage of the silkworm. From the ant silkworm to the first molt is the first age; after waking up from sleep, it enters the second age; after molting again, it enters the third age; after the third molt, it enters the fourth age, and the fourth molt is also called the long sleep. After the long sleep, it enters the fifth age. The fifth-age silkworm grows very fast, with a body length of 6 to 7 cm and a weight of about 10,000 times the weight of the ant silkworm.

Mature silkworms: When silkworms reach the end of the fifth instar, they gradually show the characteristics of maturity: first, the feces they excrete change from hard to soft, and from dark green to leaf green; their appetite decreases, and the amount of food they eat decreases; the front digestive tract is empty, and the chest becomes transparent; then they stop eating completely, their bodies shorten, and their abdomens tend to be transparent; their head and chest are raised, they spit out silk threads from their mouths, and they swing left and right and up and down to find a place to build their cocoons. Such silkworms are called mature silkworms.

Cocooning during the adult stage: People put mature silkworms in special containers or on cocoons, and the silkworms will spin silk and make cocoons.

2. The whole process of silkworm rearing?

1. Hatching silkworm eggs: Place the silkworm eggs in a warm place such as an electric blanket or pocket.

2. Feeding food: Provide silkworms with fresh, dry mulberry leaves once a day.

3. Clean regularly: Clean the paper box once a day to remove any remaining food and feces.

4. Note: When the silkworms are making cocoons, put some dry branches and bamboo strips in the paper box.

3. The process of raising silkworms?

step

(1) Place the silkworm eggs in a clean and odor-free silkworm rearing box. From the time the silkworm eggs leave the warehouse, they will naturally hatch into larvae in about 11 days (including the shipping time) at room temperature of 21-29°C.

(2) The larvae begin to have an appetite about 40 minutes after hatching, and can be fed. You can cut the mulberry leaves into small pieces with a knife and put them in the silkworm box. The silkworms will actively climb onto the mulberry leaves to eat. For 1-3 day old silkworms, you can choose tender mulberry leaves, and for 4-5 year old silkworms, you can use ordinary mulberry leaves.

(3) Silkworms grow well in an environment of 22-29°C, with the optimum temperature being around 27°C. Feeding can be done in the morning or at noon.

4.5 What are the steps to raise silkworms?

The growth of silkworms can be divided into five stages: eggs, larvae, mature silkworms, cocoons, and moths. Under normal feeding conditions, it takes 20 to 28 days for the larvae to hatch and eat mulberry leaves, spin silk and make cocoons; it takes about 3 days to spin silk and make cocoons; it takes another 1 to 2 days to pupate; after 10 to 15 days of pupal stage, it will turn into a moth, and the total process is about 40 days, and the moth will become an adult.

5. What are the five stages of silkworm growth?

Sericulture is generally divided into five processes, namely silkworm eggs, silkworm ants, mature silkworms, silk cocoons and silkworm moths.

The outer layer of the silkworm egg is a hard eggshell, and the inner layer is yolk and serosal membrane; the ant silkworm is hatched from the silkworm egg, with many fine hairs, very small, and looks a bit like an ant; the mature silkworm is the larvae that have developed to the last stage, gradually stop eating mulberry, and the silkworm body shrinks and becomes slightly transparent; the silkworm cocoon is the cocoon of the silkworm, the sac-shaped protective layer of the silkworm pupae; the silkworm moth is formed in the cocoon, shaped like a butterfly

6. What is the whole process of spring silkworm breeding?

The eggs laid by silkworm moths → hatching → pupae → moths, will complete the cycle of a new generation and enter the growth process of the next generation. First, put the floating silkworms into a clean dustpan, wipe off the moisture on the mulberry leaves and put them in the silkworms. There are five stages in silkworm rearing: silkworm eggs - larvae - mature silkworms - cocoons - silkworm moths, a total of more than 40 days.

The characteristics of spring silkworm breeding are mild weather, good leaf quality, and some pathogens killed by the cold weather in winter. The environment is clean, making it easy to obtain high-quality and high-yield silkworms. However, the temperature is often low during the young silkworm period, which does not meet the requirements for young silkworm breeding and requires heating.

7.How many steps are there in silkworm breeding?

There are five stages in silkworm rearing: silkworm eggs - larvae - mature silkworms - silk cocoons - silk moths, which takes a total of more than forty days.

Additional information

Sericulture is an important skill created by the working people in ancient China. It is said that the method of planting mulberry trees and raising silkworms originated from Leizu, the wife of Huangdi. The ancestor of the domestic silkworm is believed to be the wild silkworm (B. mandarina), which is almost the same as the domestic silkworm in appearance, and can naturally hybridize with the domestic silkworm to produce offspring after growing up.

Place the silkworms in a paper box or a small sieve for sifting rice. If using a sieve, place some paper at the bottom of the sieve.

When the silkworms have just hatched from the eggs, you need to be especially careful with them, feed them with relatively tender mulberry leaves, and use a very soft brush to move them when changing the mulberry leaves, and pay attention to the strength; sometimes the mulberry leaves are too dry, and if you are not careful, the silkworms will be left on the mulberry leaves that are about to be discarded. It is a little difficult to raise them when they are young, but it will be easier to handle when they grow up.

When it is about to make a cocoon, just take some wheat straw and tie it into the shape of branches.

After the moths break out of their cocoons, place them together in a box. They will mate together and lay eggs. Sometimes, because there are few silkworms, some moths will be left alone when they break out of their cocoons, but don't worry, as long as one pair of moths succeeds, I believe it will be enough for you to raise.

Mulberry leaves should be fresh. You can also collect them in a plastic bag each time, use a few leaves a day, and keep the rest in the refrigerator (4℃) to keep them fresh (do not water them, as the leaves will turn yellow quickly if you water them. It is recommended to seal them in a fresh-keeping bag). The collected leaves will have some dust, so you can wash them and dry them. You must dry them, otherwise the young or adult silkworms will have diarrhea after eating them, and they may even die.
