CATDOLL : CATDOLL: What are the precautions and taboos for raising silkworms? (What are the precautions and taboos for raising silkworms?)

1. What are the ten taboos in silkworm breeding?

1. When raising silkworms, it is taboo to put children's shoes in front of the bed after they go to sleep, and the adults in the family must keep the shoes away.

2. During the silkworm-raising season, the silkworm house is marked with red paper with the words "nurturing silkworms" or "knowing etiquette in the silkworm month" and posted on the door, or peach branches or camellia flowers are planted next to the silkworm house, which are said to avoid "conflicts". In some places, silkworm farmers often put straw curtains under the corridor and plant willow branches at intervals to indicate that silkworms are prohibited.

3. People believe that silkworms are extremely delicate and sacred, and therefore extremely spiritual animals, and that they can be harmed if not handled with care. The Huzhou Prefecture Records during the Qianlong period of the Qing Dynasty quoted the Wuxing Silkworm Book, which pointed out this point vividly: "Silkworms must be prevented from disease at all times from childhood to old age. Silkworms are commonly known as worry insects, and if they are sick, the harvest will be poor."

4. The custom of raising silkworms has existed in China for more than 2,000 years. From the Shang and Zhou Dynasties to the Qin and Han Dynasties and up to the Ming and Qing Dynasties, the state has included the Silkworm God in the sacrificial ceremonies. The people are even more pious in their sacrifices to the Silkworm God and dare not neglect them.

2. What are the things to pay attention to when raising silkworms, feeding them and laying eggs?

1. Temperature: Silkworms are very afraid of cold, so we always hear about spring silkworms. There is also a famous poem that only mentions spring silkworms, which is "The silkworm may not stop spinning silk until it dies, and the candle may not stop shedding tears until it turns to ashes." Therefore, we must pay attention to the breeding temperature when raising silkworms. Usually April and May are the best times to raise silkworms. The temperature at this time is basically around 20 to 25 degrees. We don't need to spend a lot of effort to adjust the temperature of the breeding room. Therefore, through the adjustment of temperature, the practice of raising silkworms in other seasons gradually emerged.

2. Mulberry leaves

When raising silkworms, you should pay attention to the fact that mulberry leaves should be fresh. At most, mulberry leaves that have been left at home overnight can be used to feed silkworms, but if the leaves are not fresh for too long, the silkworms will have diarrhea after being handled or will not eat them at all. The second thing to pay attention to is that the mulberry leaves must be cleaned and dust-free. At the same time, you cannot feed the silkworms mulberry leaves that have dew on them or that are not dry after washing, because the silkworms will have diarrhea and then die after eating them. Finally, mulberry leaves that have been sprayed with agricultural drugs not long ago cannot be picked and fed to silkworms, because silkworms are particularly sensitive to toxins.

3. Hygiene

We all know that the living habits of silkworms are the same as pigs, eating and sleeping, sleeping and eating, but silkworms are much more fragile than pigs, so the requirements for the sanitation of the breeding room are also relatively high. Many farmers have to clean up every few days during breeding. In fact, this is wrong. It is usually best to clean up every day. Although silkworm feces have certain medicinal value, they will produce bacteria in the breeding room and cause some diseases. In addition, we must clean out the silkworm skin and leftover mulberry leaves in time, especially food residues.

4. Management

In fact, attention should be paid to the management of silkworms during the feeding, daily life and cocooning period. In feeding, it should be noted that mulberry leaves should not be fed all at once. Generally, they should be fed at least twice a day in the morning and evening. Secondly, in daily management, it should be noted that incense should not be used in the breeding room, and mosquito coils, perfumes and other things with strong odors should not be placed in the breeding room. Otherwise, the silkworms will not be able to bear it and will die. Finally, during the cocooning period, we need to prepare a place for the silkworms to cocoon, so that they will not be so laborious when cocooning. If we do not provide assistance, they may become pupae before the cocoons are completed.

5. Disease prevention

There are many minor diseases that may occur during silkworm rearing. For silkworm rearing, disease prevention is the main approach. The sick silkworms should be taken out for isolation and disinfected with special agents. Sick silkworms should not be thrown away randomly, as they are highly contagious. Mites, rats, chickens and other animals should not be allowed into the breeding room, otherwise there will be heavy losses.

3. What are the six taboos in silkworm breeding?

1. On the birthday of the "Silkworm Goddess", silkworm farmers burn incense and worship at home, hoping to get the protection of the "Silkworm Goddess" and thus have a good harvest. Before and after the worship, no one is allowed to talk, and even less to dig the soil or weed.

2. When raising silkworms, silkworm breeders still have language taboos. For example, the words "silkworm", "crawl", "stiff", "sauce", "stretch", "bamboo shoots" and "onions" are respectively called "silkworm babies" and "walk". The last few words are all homophonic and represent unlucky things, so they are very taboo about people saying these words.

3. When they go to bed, they hate it if children put their shoes in front of the bed. Adults usually put children's shoes away. Of course, the specific reason comes from a beautiful legend. It is said that it is to protect the silkworms from harm.

4. In the process of raising silkworms, some small animals will enter, especially snakes. They will be very happy when they see them, and will not be afraid, let alone drive them away. They think that it is the willow fairy who came to protect the silkworms. It also indicates that there will be a good harvest this year.

5. Silkworm breeders have a custom, which they call "closing the silkworm door" and "opening the silkworm door". When "closing the silkworm door", they will insert peach branches on the door, or willow branches on the fence to tell others that now is the silkworm ban period and they should not interact with others. The ban will be lifted when the cocoons are collected, which is called "opening the silkworm door".

6. Silkworm breeders hate to use damaged silkworm trays, as that means "silkworms falling down", which is the thing they least want to see and is also an unlucky thing.

Things to note when raising silkworms

1. The silkworms are very small and have dark black bodies. When feeding them mulberry leaves, it is best to pick the tender mulberry leaves. It is also best to cut a small piece with scissors to make it easier for the silkworms to eat.

2. When the silkworms grow up a little, the mulberry leaves do not need to be cut, but the tender leaves are still the main ones, which is convenient for the silkworms to eat. They are now slightly white. Since the mulberry leaves are tender, they dry very quickly, so pay attention to adding leaves in time.

3. The silkworms eat more vigorously, grow faster, and have a good appetite, so it is easy to reach the time of molting. That is, the silkworms do not move much, and then begin the process of molting. Don't think it is sick and rub it.

4. After the fourth molting, the silkworm's body has become more transparent and is ready to start spinning silk. After about 5 days, the cocoons can be harvested.

5. Silkworms basically spend their entire lives eating. For those who raise silkworms in cities, the most troublesome thing is the mulberry leaves. If there are some in the garden, it is best to pick them. If not, you can buy them online or in the local market. Before feeding mulberry leaves, please be sure to wash the leaves, wipe them dry and then feed them to the silkworms, so that they are not prone to diarrhea or even death.

6. If it is difficult to obtain mulberry leaves, you can go out and pick them, pack them up, sprinkle some water on them and put them in the refrigerator to keep them fresh. This way, the silkworms can eat mulberry leaves every day. If there are really no leaves, you can also feed them some vegetable leaves, such as camphor leaves or lettuce leaves.

7. If you find that silkworms are not allowed to eat for several consecutive days, and it is a collective state, then you should pay attention to two issues. One is the hygiene of the mulberry leaves, whether they are washed clean, whether there are pesticides, etc. The other is whether the mulberry leaves have moisture and are not wiped dry, which will cause the silkworms to get sick. If none of these are present, you need to consider the surrounding environment. Too fragrant, too humid, or too dry is not good. Young silkworms have strong resistance to high temperature and humidity. Generally, the silkworm room is maintained at 25-28℃ and the relative humidity is 75%-80%. Adult silkworms are suitable for an environment with slightly lower temperature and humidity and good ventilation. Generally, the silkworm room is maintained at 23-24℃ and the relative humidity is 60%-70%.

5. What should we pay attention to when raising silkworms?

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 are less resistant to external interference during their dormancy, so you must pay attention to their protection during dormancy. When 95% of the silkworms have fallen asleep, sprinkle them with fresh lime powder and silkworm medicine "Disease Prevention No. 1" to prevent pathogens from invading. If a small number of silkworms do not eat mulberry and do not sleep, it is because they have not found a place to sleep. At this time, add some mulberry leaves to help them sleep 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 weather 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.

6. What should we pay attention to when raising silkworms?

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.

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.

9. Avoid feeding wet leaves in hot and humid weather. Do not water the stored mulberry leaves. Remove sand frequently and sprinkle more fresh lime powder, dry straw and other materials to inhibit the growth and reproduction of pathogens.

10. When it is not the silkworm-raising season, do not store grains, bran and other items in the silkworm room to avoid moisture and the generation of mites, which will harm the silkworms during breeding.

Five common misunderstandings about the use of drugs in silkworm rearing In recent years, many silkworm farmers have used excessive and unconventional drugs in the prevention and treatment of silkworm diseases, which has resulted in drug poisoning of silkworms and aggravation of the disease, causing unnecessary losses in silkworm production. The author introduces the five common misunderstandings about the use of drugs in the silkworm rearing period as follows for reference by silkworm farmers.

1. The misunderstanding of using drug carriers is to spray silkworm medicine on mulberry leaves to add food to silkworms. Mulberry seedling planting technology and mulberry tree disease and insect pest control should be sprayed (sprinkled) on silkworm bodies, silkworm seats, and silkworm webs, which should be determined according to the disease type and drug type. But the actual situation is that drug carriers are often confused. For example, "Fangjiangling No. 2" is often sprayed on mulberry leaves by some silkworm farmers as a food drug, which often leads to poisoning and death of silkworms. And "Chloramphenicol for Silkworms" and "Kanjun Bacteria" that should be used to add food are often used on silkworm bodies, which is not only ineffective but also misses the best time to prevent and control silkworm diseases.

2. Misunderstandings in drug selection Some silkworm medicines are quite similar in appearance and color, and are often used incorrectly. "Big Silkworm Disease Prevention No. 1" and "Small Silkworm Disease Prevention No. 1" are only one letter different, both are bagged powders, but the concentration of the active ingredient - formaldehyde is significantly different, the former is 2.5%, and the latter is 1.25%. If they are used in reverse, it will cause drug damage to small silkworms and poor effect on large silkworms. According to the Agricultural and Forestry Network, "Fangjiangling No. 2" and "Mi Canfei" are often mixed because of their similar colors. More silkworm farmers do not know the efficacy of silkworm medicines and cannot choose the right medicine when selecting. What's worse, because they think the medicine is not strong enough, they mix and use multiple silkworm medicines, which actually promotes chemical reactions between the medicines, making the silkworm medicine lose its original efficacy and even causing drug damage. For example, "Fangbing No. 1", "Mi Canfei", "Fangjiangling No. 2" and other alkaline drugs such as lime powder should not be mixed at the same time.

3. Misunderstandings about the timing of medication. For example, when using lime powder during the dormancy period, there is no time distinction. Some people use it until the late dormancy period, causing the silkworms to molt half or not at all. "Anti-rigidity powder" works best when used before feeding at the beginning of the instar, but some silkworm farmers use it at the end of the instar when the silkworms are about to dormancy.

Fourth, the misunderstanding of the dosage of medicine is often manifested in insufficient dosage, excessive dosage, insufficient or too frequent dosage. For example, the dosage of "Ultra-Clean" fumigant used in the young silkworm stage is confused with the dosage used for disinfection before silkworms are killed, and 5 grams are used per cubic meter of space instead of 1 gram. In addition, when preventing and treating silkworm fly maggot disease, some people use "silkworm fly killing" once in the fifth instar of silkworms and think that it is enough, resulting in countless maggot holes and silkworms when collecting cocoons.

5. Mistakes in drug preparation: Drug preparation is based on guesswork and the concentration of the original drug is not taken into account, resulting in a high or low concentration. For example, when preparing bleaching powder to prevent stiffness, the effective chlorine concentration should be 2% for young silkworms and 3% for adult silkworms. However, in the prevention and control of silkworm diseases, the phenomenon of excessive effective chlorine concentration causing poisoning and death of adult silkworms occurs in almost every region and every season.

7. 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.
