CATDOLL : CATDOLL: What matters and details should be paid attention to when raising silkworms (What matters and details should be paid attention to when raising silkworms)

1. What are the things to pay attention to when raising silkworms?

Tools/Raw Materials

Plenty of mulberry leaves

Methods/Steps

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.

2. How to raise silkworms at home?

After receiving the silkworm seeds, place them in the prepared silkworm rearing box. The silkworm box can generally be an ordinary paper box, but it must be kept clean and odorless. From the day the silkworm seeds are shipped out of the warehouse, they will naturally hatch into silkworms in about 11 days (including the delivery time) at room temperature of 21-29 degrees Celsius. Silkworms will have an appetite about 40 minutes after hatching, and the feeding process should begin at this time. Take the prepared fresh tender mulberry leaves out of the refrigerator, wait for the mulberry leaves to return to room temperature, cut them into small pieces with a knife and put them in the silkworm box. The silkworms will automatically climb onto the mulberry leaves to eat. It usually takes about 27 days (divided into 5 ages) for silkworms to hatch and cocoon on the mountain. It is advisable to use tenderer mulberry leaves for feeding silkworms from the first to third ages, and ordinary mulberry leaves for silkworms from the fourth and fifth ages. Silkworms are suitable for growing in an environment with a temperature range of 22-29 degrees Celsius, and the most suitable growth temperature is about 27 degrees Celsius. A silkworm eats about 25 grams of mulberry leaves in its lifetime. For example, if you want to feed 40 silkworms, you only need 1 kg of mulberry leaves. However, in the actual feeding process, some mulberry leaves will be wasted, so more mulberry leaves will be needed. After the fifth instar, silkworms will stop eating mulberry leaves and start looking for a suitable place to spin silk and make cocoons (also called going up the mountain to make cocoons). In rural areas, straw-bound grass hills or pine branches are generally used as silkworm hills. For silkworms fed as pets, a paper box divided into many small compartments can be used instead. Precautions for raising silkworms 1. Keep mulberry leaves fresh 1. Place mulberry leaves in the refrigerator (about 5 degrees Celsius) to prevent deterioration. 2. Tighten the plastic bag to slow down the drying and dehydration time of mulberry leaves. 2. Feeding silkworms 1. Take out the mulberry leaves from the refrigerator and wait for a few minutes for the mulberry leaves to return to room temperature before feeding. 2. Do not wash the mulberry leaves with water and keep them in a natural state. 3. For feeding the second-instar silkworms, please choose tenderer mulberry leaves, 1-2 pieces per day. 4. The feeding time can be chosen in the morning or at noon. 3. Other matters needing attention 1. Do not catch silkworms with your hands, use the soft bristles of a brush to drive them away; 2. Clean the silkworm room every day; 3. The silkworm room should be placed in a cool place (around 25 degrees Celsius).

3. Secret tips for raising silkworms?

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.

4. What should you pay attention to when raising silkworms personally?

1. Silkworms are particularly allergic to medicines, so make sure there are no medicines; 2. There must be enough mulberry leaves for the silkworms to eat; 3. The environment must be large enough; 4. The environment must be clean enough.

5. What should I pay attention to when raising silkworms? When should I change the mulberry leaves? When does it mean that the silkworms are sick?

I hope my answer can help you.

Usually, silkworms are raised indoors on the ground and outdoors on scaffolds during the silkworm raising season. When raising silkworms, 5 ml of fermentation liquid can be added to one catty of water, and 10 catties of mulberry leaves can be sprayed to add food. Screen doors and windows should be installed in the silkworm room, and sick silkworms should be cleaned up in time. In spring and summer, the growth cycle of mulberry trees should be roughly the same to ensure an adequate supply of mulberry leaves.

How to raise silkworms

1. Rearing method: 4-5-year-old silkworms are in the adult stage, and the suitable growth temperature is 25 degrees. Silkworms have weak resistance to high temperature, humidity and carbon dioxide, eat a lot of mulberry leaves and excrete a lot. They can be raised on the ground indoors or on outdoor sheds.

2. After receiving the silkworm eggs, protect them in a suitable environment to allow the embryos to develop normally. The specific method is: in a disinfected silkworm room, spread the silkworm eggs flat on the silkworm plaque with the eggs facing upward. The room temperature should be 24℃ and the dry-wet difference should be 2-2.5℃ for the first 4 days. The room temperature should be 27℃ and the dry-wet difference should be 1.5-2℃ for the fifth to tenth days. When the embryos develop to the later stage and a small number of silkworm eggs are found to be blue dots, immediately cover the silkworm eggs with black cloth. After about 40 hours, that is, 4-5 o'clock before dawn on the third day, remove the black cloth, wrap the silkworm eggs with white paper, with the eggs facing upward, turn on the light to let the ants bite through the egg shells and hatch.

3. The main technical measures for raising silkworms are:

⑴ Improve the environment and ensure ventilation to prevent stuffiness.

⑵ Build a shed to provide shade and prevent hot air from entering the silkworm room.

⑶ The silkworm seats should be placed sparsely and low, and fed frequently and in small amounts.

⑷ Pay close attention to the management of the mulberry garden, ensure the quantity and quality of mulberry leaves at the fifth age, so that the silkworms can be well fed and eat well, and prevent the silkworms from eating old and hard leaves, too tender leaves, malnourished leaves, and leaves that lack water.

Details to pay attention to when raising silkworms

1. Remove sand before dormancy. This is to avoid excessive accumulation of silkworm feces, which can easily breed and spread pathogens and invade the silkworms during their dormancy.

2. Silkworms do not eat or move during the dormant period. They mainly rely on the nutrients absorbed by eating mulberry before dormancy to maintain their life activities. Therefore, they must sleep when they are full. If you stop feeding mulberry too early, they will starve to sleep. Starved silkworms are weak in constitution, poor in resistance, and prone to illness.

3. Silkworms have weak resistance to various external interferences during their hibernation period, so it is important to pay attention to their protection during sleep.

When 95% of the silkworms have settled, fresh lime powder and silkworm medicine "Disease Prevention No. 1" should be sprinkled on them to prevent pathogens from invading. If a small number of silkworms do not eat mulberry and do not settle, it is because they have not found a place to settle. At this time, some mulberry leaves should be added to settle the silkworms in batches.

4. Silkworms are temperature-changing animals, and their adaptability range is 20-30℃. In the spring silkworm period, the climate is often low and humid, so the focus is on replenishing warmth and removing moisture. In the summer silkworm period, the climate is hot and humid, so the focus is on cooling and removing moisture, keeping the air in the silkworm room flowing, and removing the stuffiness. In the autumn silkworm period, if the climate is hot and dry, it is necessary to replenish moisture indoors and combine disinfection, that is, spray the ground and walls with fresh lime powder and bleaching powder; you can also hang a wet cloth on the silkworm rack to keep the silkworm room moist to prevent the silkworms from having difficulty molting or half molting.

Silkworm breeding technology

1. Spray mulberry leaves to feed silkworms: add 5 ml of fermentation liquid to 1 kg of water, spray 10 kg of mulberry leaves to feed them, once a day. Silkworms love to eat, their feces are not smelly, they grow fast, their cocoons are thick and of good quality, and they can increase production by about 10%.

2. Spray the silkworms to cool down and relieve heat: In summer, the temperature is high, silkworms are prone to illness, and if the room temperature is too high, silkworms are prone to heatstroke and death. In hot weather, add 5 ml of fermentation liquid to one pound of water and spray it on the silkworms, once in the afternoon and once every day.

3. Spray mulberry leaves to keep them fresh: In summer, when the temperature is high, the collected mulberry leaves will turn yellow and deteriorate if they are piled for a long time. In autumn, when the climate is dry, the collected mulberry leaves will dry out and become hard if they are kept for a long time. You can add 5 ml of fermentation liquid to one pound of water, use it to wet the mulberry leaves, then put the mulberry leaves into a woven bag or pile them on the ground, cover them with plastic cloth, and they will remain as fresh and green as before after 24 hours.

4. Spray mulberry leaves to promote growth: add 1-2 ml of fermentation liquid to one pound of water, spray the mulberry leaves in the mulberry field, spray 2-3 times a month, add 0.2% potassium dihydrogen phosphate for better effect. Spray until the mulberry leaves are completely wet without dripping. Mulberry leaves grow fast, the leaves are green and thick, and the yield can be increased by 20-25%. It can also reduce diseases and insect pests.

Note: Antibiotics cannot be used 6 hours before and after using the Vitality 99 Fermentation Agent fermentation liquid. No matter how long the fermentation liquid is stored, as long as it still has a sweet and mellow aroma, it can be used. If it smells, it cannot be used.

Precautions for raising silkworms in summer and autumn

1. Prevent pesticide poisoning. During the silkworm-raising season, do not spray the farmland near the silkworm room with organochlorine pesticides such as dimethoate, as the fumigation effect 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.

4. Before raising silkworms, rat holes should be blocked, silkworm racks should be kept at a certain distance from the wall, and lime powder or silkworm medicine should be sprinkled around the legs of the silkworm racks to prevent rats from climbing up. When raising silkworms, drugs should be used to kill rats.

5. In summer and autumn, the temperature is high when raising silkworms. Open doors and windows to increase indoor ventilation. Spraying mulberry leaves with clean water and using electric fans to blow breeze indoors can also help cool down the room.

6. If sick silkworms are found, they should be cleaned up in time and placed in a disinfection basin filled with bleach solution or lime slurry. It is forbidden to feed sick silkworms to livestock and poultry to prevent the spread of pathogens and pollute the environment.

7. Silkworm feces contain a large amount of pathogens. Do not spread them out to dry around the silkworm room. Instead, compost them in a pile outdoors or in a manure pit to prevent the spread of pathogens.

8. In summer and autumn, the temperature is high and pathogens multiply quickly. Pay attention to picking leaves on demand, transporting leaves in time, and storing leaves properly. The mulberry pool should be disinfected once for each age, and do not feed mulberry leaves overnight.

6. Tips for raising silkworms for children?

1. From silkworm ants to silkworm babies:

Suitable temperature: 20-25℃, time: 2-3 days for incubation.

Collecting ants: The little silkworms will crawl out of the egg shell like ants. Use very light gestures to collect and lead them to the tender leaves.

Note: Silkworm eggs need to be kept in a ventilated and dark place during hatching period.

Method/Step 2:

2. Feeding silkworms:

The living habits of silkworms are: sleep when full, eat when awake;

Living environment: Plastic or wooden flat box,

Note: The mulberry leaves should be fresh. You can also collect them in a plastic bag each time, use a few leaves every day, and sprinkle some water on the rest and put them in the refrigerator to keep them fresh. 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 if they eat them.

Method/Step 3:

3. Silkworms spin silk and make cocoons:

Molting: After molting once, the larvae become the second-instar larvae. Each time the larvae molts, they become one year older. They molt a total of four times.

Cocooning: 7-8 days after molting four times, the owl stops eating mulberry leaves, its body starts to shine, and it begins to look for a suitable place to start cocooning.

Note: Put some supporting objects in the silkworm box to help the silkworms make cocoons.

Method/Step 4:

4. About silkworm droppings:

Silkworm feces, which consist of black particles, can be used as medicine in traditional Chinese medicine and are also a good nutrient for plants.

Silkworm excrement, also known as silkworm sand, has the effects of curing dampness, curing itching, removing internal heat, removing rheumatism, and improving hearing and eyesight. Many elderly people dry it and make it into pillows for their newborn babies to sleep on.

Method/Step 5:

5. Silkworms emerge from their cocoons:

The silkworm sheds its skin for the final time (fifth time) in the cocoon and becomes a pupa. After about 7-10 days, the pupa turns into a silkworm moth and emerges from the cocoon.

Note: The fat one is the mother of the silkworm, and the thin one is the father of the silkworm. Let the father and mother of the silkworm live together, and you can see a lot of silkworm eggs the next day. If you protect them well, these silkworm eggs can hatch again in the spring of the next year.

Method/Step 6:

6: Note: Silkworms are particularly sensitive to fragrance, so perfume, mosquito coils, air purifiers, scented cosmetics, etc. are not allowed. Any type of pesticide is absolutely prohibited! Raising silkworms can stimulate children's creativity, interest, and touch life, which is conducive to improving children's hands-on ability and observation ability. It is also a good content of family affection activities. The following is a picture of the harvest of our silkworm raising~~
