CATDOLL : CATDOLL: Record of the whole process of silkworm breeding (how to write a record of the whole process of silkworm breeding)

1. What is 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.

2. 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.

3. 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.

4. What is 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.

5. My experience in raising silkworms?

1. Early in the morning, I went to the countryside to pick the best and tenderest mulberry leaves from the mulberry trees. The black silkworms were placed on the mulberry leaves I had just picked. They were small and black! One leaf was enough for many silkworms to eat. Eat it, eat it, and grow up quickly.

2. In just a few days, the silkworms have grown so big, and they are so cute. Every time they grow a little bigger, they will shed their skin, so remember to clean the silkworms' home.

3. There are not enough mulberry leaves. The grown silkworms have a big appetite. At night, you can only hear them munching on the food. I have to go prepare some mulberry leaves. The mulberries on the tree haven’t grown well yet, but they have already eaten all the leaves.

4. Eat, eat, eat. The fat and white silkworm will shed its skin four times and become a fifth-instar silkworm. At that time, the silkworm will spin silk and make a cocoon after eating mulberry leaves for a few days.

5. This is a silkworm spinning silk. At this time, the color of the silkworm looks slightly yellowish, and the yellow is transparent, especially the chest. You can already see the silk inside its body.

6. A silkworm will not stop spinning silk until it dies! Look, many moths are looking for their mates.

1. Hatching silkworm eggs

When raising silkworms, you need to obtain silkworm eggs that are round and black in color, wrap them in paper towels, and place them in a warm environment such as an electric blanket or pocket. The silkworm eggs will hatch after one day. At this time, you need to prepare a paper box, spread tender mulberry leaves on the bottom, and then put the young silkworms in it.

2. Provide food

Silkworms feed on mulberry leaves, so they should be provided with fresh mulberry leaves once a day and the leftover mulberry leaves from the previous day should be cleaned up. Silkworms do not drink water and get the required water from the leaves, so the mulberry leaves provided should be wiped dry in advance to avoid residual moisture, which will cause diarrhea and death of the silkworms.

3. Clean up regularly

Silkworms will constantly eat and excrete during their growth process. When breeding, their feces should be cleaned once a day to ensure a clean and hygienic environment. Silkworms have many natural enemies, and animals such as birds and ants will prey on them. Silkworms should be placed in a safe environment and the sealing of the container should be checked regularly.

4. Cocoon management

One month after hatching, the silkworms will enter the cocoon-making stage. At this time, the silkworms can spin silk and make cocoons in the corner of the paper box. However, if the number of silkworms is large, it is best to put bamboo strips or branches that have been removed of leaves and disinfected in the paper box to provide a place for the silkworms to make cocoons.
