CATDOLL : CATDOLL: What are the tips for raising silkworms? (What are the tips for raising silkworms?)

1. What are the correct methods and techniques for raising silkworms?

1. Mulberry leaves should be picked, transported and stored properly. Try to pick leaves in the morning or evening, transport them as soon as they are picked, and pack them loosely for fast transportation. After the picked mulberry leaves are loosened, put them in the mulberry storage pool or mulberry storage room, and store them properly to prevent them from being blown away by the wind or piled up and heated and deteriorated, which will cause waste of mulberry leaves.

2. Prevent mulberry leaves from wilting. During the young silkworm stage, use a kang bed (room) and cover the mulberry leaves with plastic film to keep the temperature and moisture, so that the mulberry leaves remain fresh. During the adult silkworm stage, close the doors and windows appropriately after feeding the silkworms, and open the doors and windows for ventilation after the silkworms have eaten about 70% of the mulberry leaves, which can effectively prevent the mulberry leaves from wilting.

3. Ensure the temperature of the silkworm room. The suitable temperature for large and small silkworms is 24℃ and 25℃ respectively. Within the suitable temperature range, the silkworms have a strong appetite, which reduces the defective mulberry leaves and improves the leaf-silk conversion rate.

4. Promote less-return rearing and mulberry-strip rearing. Labor-saving silkworm rearing technologies such as flat three-dimensional rearing of small silkworms once a day, rearing of full-age silkworms twice, and rearing of large silkworms in mulberry strips not only improve the efficiency of silkworm rearing, but also help silkworms eat mulberry leaves, saving about 5% of mulberry leaves compared with ordinary rearing.

Summer and autumn silkworm breeding should pay attention to

1. Prevent pesticide poisoning. During the silkworm-raising season, do not spray organic pesticides such as dimethoate in the silkworm room and the fields near the mulberry fields, as the smell will cause poisoning to the silkworms; mulberry leaves should be fed to the silkworms only after they have been tested and confirmed to be non-toxic.

2. Mosquito-repellent incense or mosquito repellent or insecticide is prohibited in the silkworm room. If it is used in the house near the silkworm room, the doors and windows of the silkworm room should be closed to prevent the silkworms from being poisoned.

3. Screen doors and windows should be installed in the silkworm room to prevent flies from entering the room and harming the silkworms, and "silkworm fly killing" emulsion should be added or sprayed on the silkworm bodies to kill the maggots.

2. How to raise silkworms?

1. Place the silkworm eggs in a box and wait for them to hatch. The most suitable temperature is 25℃-28℃. If the temperature is lower, you can cover the box with a lid.

2. Newly hatched silkworms must be cared for with special care and fed with relatively tender leaves.

3. When the silkworm is dormant, it does not eat or move. On the surface, it is sleeping, but in fact it is shedding its old skin and replacing it with a new one to continue growing. The silkworm will shed its skin 4 times during the whole breeding process. Each time it sheds its skin, it will not eat or move. At this time, try not to disturb it, and do not throw it away thinking it is sick. Each dormant period of the silkworm lasts about one day.

4. Generally, the silkworms start to spin cocoons around 25 days old. When the silkworms' backs are shiny, yellow and transparent, it means that they are about to spin silk and spin cocoons. At this time, a cross space should be provided for the silkworms to spin cocoons. It takes two days to spin a complete cocoon, and the silkworms complete the last molting in the cocoon and become pupae.

5. Male and female silkworm moths mate shortly after emerging from their cocoons. After mating, the female moth takes 4-5 hours to lay 400 eggs and then slowly dies.

3. What are the tips and things to note when raising silkworms?

1. Silkworms are still easy to buy, but if you have no experience, it is not recommended to start from unhatched eggs, as they have higher requirements for temperature and humidity, and the whole process takes less than 30 days.

2. It is recommended to start from the second or third instar. The survival rate is high and it is easy to handle. Otherwise, if the silkworms are too young, you have to be very careful when putting mulberry leaves every day. It is really troublesome to change mulberry leaves for ant silkworms.

3. In the early stage, you can find a paper box to raise it, and spread mulberry leaves on the bottom of the box, and spread 2 layers. Mulberry leaves are generally changed every 1-2 days, and the old leaves in the box should be cleaned out.

4. You can cover the box with plastic wrap and then use a toothpick to make a few holes in it. Put the box in a cool place away from direct sunlight. Adult silkworms have a strong ability to adapt to the environment.

5. In reality, mulberry trees are not easy to find, so they are mainly purchased online. They can be placed in the refrigerator at 0 degrees to keep fresh. Take them out of the refrigerator before each use and moisten them with clean water.

6. Raising silkworms is relatively easy as long as there is sufficient food. If you just want to complete the operation, you can put them in a box during the cocooning period. Otherwise, you need to find a slightly larger box and put some small wooden racks to facilitate cocooning.

4. How to raise silkworms?

Step/Method 1

Prepare a cardboard box of corresponding size according to the number of silkworms you raise, put A4 paper on the bottom of the box, and place a board on the box to prevent mice from eating the silkworms.

Step/Method 2

Put the silkworm eggs into a box, place the box in a place with suitable temperature, and sprinkle a little water in the box to increase the hatching rate.

Step/Method 3

Use scissors to cut the fresh mulberry leaves into pieces and feed them to the silkworms. Be sure to wipe the water off the selected mulberry leaves with a rag, otherwise the silkworms will get sick after eating them.

Step/Method 4

When the silkworms grow up and are about to spin silk, they will not like to eat much. At the same time, their feces will change from dark green to turquoise. You can put the silkworms that are about to spin silk in a box. Do not open the lid frequently and wait patiently for them to turn into silkworm pupae.

5. Secret recipe for raising silkworms?

Choose healthy silkworms with large silk production, keep the room temperature at around 25℃ and the air humidity at around 60%. There should be no irritating odor in the silkworm room and attention should be paid to ventilation.

The main feeding material is fresh, tender, and waterless mulberry leaves, which can be increased or decreased according to the age of the silkworms.

From the third age onwards, the sand should be removed once a day and the silkworms should be placed on cocoons at the appropriate time. When the silkworms are old, they should be selected in batches and placed on cocoons sparsely.

Young silkworms develop quickly, sleep quickly, and have a short sleep period, so the sleeping net should be put down earlier; the fourth-instar silkworms have a long sleep period, so the net should be put down later.

It is better to go to bed early in hot and humid weather, and late in cold and dry weather. It is better to go to bed early in the morning and late in the afternoon.

When there are a small number (2-3) sleeping silkworms on the silkworm nest, sprinkle rice bran ash or fresh lime powder (to make the silkworms climb up quickly), add a sleeping net, and give mulberry leaves (ripe but slightly tender). The process can be carried out after all the silkworms have climbed up.

If you add a sleeping net at night, you should give it a dose of mulberry leaves the next morning before sleeping.

6. Top ten tips for raising silkworms?

Silkworm breeding method

1. Do a good job in disinfection and disease prevention

Because the interval between silkworm breeding in summer is short, pathogens are fresh and large in quantity, and are easy to infect, we should pay attention to environmental sanitation and thoroughly disinfect the silkworm room and silkworm tools. You can spray disinfectant first, then clean and wash them. When spraying, pay attention to the dosage and spray all the surfaces. Strictly implement the "three disinfection principles" (that is, thoroughly disinfect before silkworm breeding, continue disinfection during silkworm breeding, and disinfect immediately after silkworm breeding), and carry out disinfection and disease prevention throughout the entire silkworm breeding process.

When harvesting leaves for summer silkworms, attention should be paid to the safe interval of pesticide application. Mulberry leaves from areas where pesticides are applied must be harvested and fed after the residual period has expired. Only after they are proven to be non-toxic can leaves be harvested for feeding. Summer silkworms should be protected from flies and rats to avoid losses.

2. Adjust the room temperature for silkworm rearing

According to the characteristics of summer climate, take corresponding measures to adjust and improve the silkworm breeding environment. In hot and humid weather, pay attention to ventilation, and cool down and moisturize when it is hot and dry. Plastic film can be used to cover the young silkworms, which can keep warm and moisturize, which is conducive to the healthy development of silkworms. In the adult silkworm period, choose a tall, spacious and well-ventilated house to prevent stuffiness. Plant trees and build a pergola around the silkworm house to reduce radiation.

3. Do a good job in mulberry leaf management

The quality of mulberry leaves is directly related to whether the summer silkworm harvest is good or not. We should strengthen the fertilization and pest control of mulberry trees to promote the growth of mulberry trees. During the young silkworm period (1 to 3 years old), it is key to pick the leaves that are ripe, with the color being pure green and soft to the touch as the standard. When collecting mulberry leaves for ants, you should choose mulberry leaves that are ripe and tender, and avoid using leaves that are not exposed to enough sunlight, old leaves, wilted leaves, diseased and insect-infested leaves, and mulberry leaves contaminated by pesticides. The leaves for summer silkworms should be picked in the morning before the dew dries or in the evening. Leaves must not be picked in the middle of the day (except on rainy days). The picked mulberry leaves should be picked and transported quickly to prevent the mulberry leaves from emitting moisture and withering. Pay special attention to not stacking mulberry leaves too high or too thick to prevent them from rotting.

4. Do a good job in feeding management

First, the transportation of silkworm eggs. When transporting silkworm eggs, do not pile them up or pile them up, and try to avoid contact with high temperatures. The transportation of silkworm eggs should be carried out in the morning and evening, and they should be spread out in time after being brought back to prevent accumulation and heating. When distributing silkworm eggs, try to do it in the morning and evening. Silkworm eggs should not come into contact with pesticides and all harmful gases to prevent silkworm poisoning.

Second, feed the young silkworms. Plastic film can be used to cover the silkworms. Silkworms grow and develop quickly, so the area of ​​silkworm seats should be expanded in advance to prevent them from being crowded and hungry. Disinfect the silkworm bodies and silkworm seats with fresh lime powder or 2% effective chlorine anti-stiffness powder every day. Add 500 times diluted silkworm disease sterilization spirit, Yijiling, and Kejunxing to feed the young silkworms when they wake up. Use 0.3% effective chlorine to soak or spray the leaves for disinfection, dehydrate, and dry them before feeding them.

Three-catch adult silkworm rearing. During the period, three sparse should be achieved: the silkworm racks in the silkworm room are sparsely connected, the silkworm foils on the silkworm racks are sparsely placed, and the silkworm heads in the silkworm foils are sparsely placed. This is conducive to ventilation, lowering the temperature, and ensuring that the silkworms are fully fed. During the adult silkworm period, especially during the hot and humid period, the silkworm litter should be removed frequently to keep the silkworm seats clean and dry. During the adult silkworm period, labor-saving silkworm rearing should be implemented. During the adult silkworm period, 300 times the liquid of fly-killing tablets should be sprayed on the silkworm bodies and 500 times the liquid should be added to the food to prevent maggots from harming them.

Fourth, cluster management. In order to reduce labor costs, it is advisable to adopt automated cluster technology. The specific method is: when the silkworms develop evenly and 5-10% of the silkworms are mature, use 4-6 pieces of Chuanto for each silkworm seed and mix 20-30 jin of mulberry leaves with cold boiled water (4-6 pieces with 1-1.5 jin of water), feed the silkworms at 10-12 pm, and no longer feed mulberry leaves. At 10-12 am the next day, sprinkle some straw or silk nets on the silkworm seat, and put plastic clusters or square clusters on the silkworm seat to let the mature silkworms automatically cluster and make cocoons. After clustering, strengthen the ventilation and dehumidification of the cluster room (use electric fans to dehumidify if conditions permit), so that the cluster room, cluster tools, and environment are dry, improve the yield and quality of silk cocoons, and ensure stable and high yields of summer silkworms.

7. How to raise silkworms?

1. Raise silkworms in paper boxes and feed them green leaves such as mulberry leaves and lettuce leaves. Young silkworms need to be fed with tender leaves, and adult silkworms also need to eat a moderate amount of old leaves to promote silk production. Before each feeding, be sure to wipe off the moisture on the mulberry leaves. In addition, be sure to separate the silkworms into boxes according to their body size.

2. Mulberry leaves are the most suitable natural food for silkworms. In addition to mulberry leaves, silkworms can also eat green leaves such as lettuce leaves, elm leaves, grape leaves, and lettuce leaves.

3. Silkworms can be raised directly in paper boxes. The paper boxes need to be kept clean and dry without moisture. When raising silkworms in a small space, do not put too many mulberry leaves at one time.

Young silkworms under 4-5 cm need to eat the tenderest leaves, while adult silkworms need to eat a moderate amount of old leaves on top of tender leaves to promote silk production. Every time you feed them mulberry leaves, be sure to wipe off the moisture on them, and remove the mulberry leaves that are not fresh enough in time.

5. It is best to separate the silkworms into boxes according to their body size to prevent them from fighting for territory. In addition, ants will eat silkworms, so you need to observe the environment when raising them and remove ants in time if you find them.

8. Tips for raising spring silkworms?

Raising silkworms is a very happy and relaxing thing. It can not only improve your patience, but also improve your understanding of biology. Sericulture technology is the key to raising silkworms. Without technology, it is impossible to raise good silkworms. There are many tips for raising silkworms. Let's take a look at these tips.

What are the tips for raising silkworms?

1. Silkworm eggs

1. Build a comfortable "home": prepare a box with a lid and poke a small hole in it. Put a layer of clean white paper inside the box and place the silkworm eggs in the paper box. If the climate is relatively dry, spray a small amount of water every day. As the weather gradually warms up, the silkworms will come out by themselves.

2. During this period, check every day to see if there are any new silkworms. Generally, the most silkworms come out in the morning. As soon as the silkworms come out of the egg shells, they will eat, so you should quickly use a brush or feather to gently brush them onto the mulberry leaves.

2. Feeding of larvae

1. Prepare food: Mulberry leaves must be washed with clean water and dried before feeding. Do not feed the silkworms with yellow and rotten leaves, otherwise the silkworms will be poisoned or have diarrhea. To prevent the excess leaves from wilting quickly, put them in a plastic bag, tie the bag tightly, and place it in a cool place.

2. Feed the silkworms with leaves 4 times a day, early in the morning, at noon, in the afternoon, and at night. The amount should be appropriate each time to avoid waste. You can put more leaves at night because the silkworms eat mulberry leaves all night. Ant silkworms should be fed with young leaves, and the leaves are best cut into pieces or strips.

3. Clean up the feces and leftover leaves frequently: When changing leaves for the silkworms, you can directly cover the old leaves with new leaves, and remove the old leaves after the silkworms have crawled onto the new leaves. This can reduce the casualties of the silkworms and facilitate the removal of leftover leaves and silkworm feces.

4. Do not spray pesticides in the silkworm room as this will harm the silkworms.

5. During the growth and development of silkworms, the epidermis cannot grow with the body. When the growth of the silkworm's body is restricted, it will shed its skin. When the silkworm sheds its skin, it does not eat or move, as if it is sleeping. After about a day, a new skin is formed and the silkworm begins to move again. When the silkworm is sleeping, do not think it is sick or dead and throw it away.

6. If you find that your child has a poor appetite, is stiff or listless, or is gradually becoming limp, or has foul-smelling fluid, etc., please consult the teacher immediately.

3. Silkworms Spin Silk to Make Cocoons

When the silkworms grow to a certain size, they will spin silk and make cocoons. The bodies of silkworms that are about to spin silk will be transparent and shiny, and they will stop eating mulberry leaves and crawl to one side, with their heads raised and swaying from time to time. At this time, you should quickly take the silkworms out and put them in a square made of paper strips, and finally cover the square with a thick paper as a cover, so that the silkworms can spin silk and make cocoons in the square.

4. Silkworm

1. Silkworms usually emerge from their cocoons in the early morning. After they emerge from their cocoons, the male and female silkworms will mate. If the silkworms are far apart when they emerge from their cocoons, and there are few of them, and they are all female or male, they will not be able to mate and will die in vain. Therefore, several students can gather the newly emerged silkworms together so that they can mate in time.

2. The female moth will lay eggs after mating. At this time, put a piece of white paper at the bottom of the box and let the female moth lay eggs on the paper for preservation.
