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%.

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

The silkworms are very small and cannot be caught by hand, nor can their life thread be broken. They need to eat tender green dry mulberry leaves, which should be put in a box and kept in a ventilated and cool place. Silkworms shed their skin four times in their lifetime and can live for about 56 days. The mulberry leaves that have rain should be dried in the shade. They should be fed every three days, and their feces should be cleaned up. Silkworms do not have noses, but use the black spots on their bodies to breathe and need air.

3. 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.

4. 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.

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. What should we pay attention to when raising silkworms?

Hello, I am glad to answer your question. We must provide silkworms with tender mulberry leaves as food, and never provide older mulberry leaves. To some extent, animals are the same as humans, just like when we were young, we couldn't eat steamed buns and some vegetables directly. The same is true for silkworms. We should provide very tender mulberry leaves, but silkworms can't eat them. So we must provide them with some fresh mulberry leaves, so that they can eat and grow normally!

7. 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.
