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

1. New technologies and methods for silkworm breeding?

1. Preparation

Before raising silkworms, be sure to prepare a clean, odor-free cardboard box, and then poke some small holes on the top of the box to facilitate ventilation.

2. Incubation

Place the silkworm eggs in a carton at a temperature of 21-29°C. The incubation time is generally about 11 days.

3. Feeding

(1) When the silkworms are about to hatch, put an appropriate amount of fresh mulberry leaves into the cardboard box for the silkworms to eat.

(2) When silkworms are in the young stage, they can be fed with fresh and tender mulberry leaves. When they are in the adult stage, they can be fed with ordinary mulberry leaves.

(3) Before feeding, be sure to check the mulberry leaves carefully to pick out diseased, moldy, and insect-infested leaves, and make sure there is no water on the leaves, otherwise the silkworms will easily suffer from diarrhea after eating them.

4. Cleaning

(1) The old mulberry leaves in the cartons must be removed regularly and replaced with fresh mulberry leaves. All silkworm feces in the cartons must be cleaned up.

(2) When changing mulberry leaves to clean the feces, you must use a brush. The silkworms on the old mulberry leaves can be gently swept onto the new mulberry leaves, and then the silkworm feces and old mulberry leaves in the cardboard box are cleaned, and finally the new mulberry leaves are put into the cardboard box.

(3) If there are dead silkworms in the carton, be sure to clean it up immediately to prevent other silkworms from being infected.

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. 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.

4. A beginner’s guide to silkworm farming?

1. Breeding for beginners

When a novice raises silkworms, he needs to prepare a clean, odor-free ordinary paper box or wooden box, then put the purchased silkworm eggs into the paper box, and place the box in a greenhouse that can regulate the temperature. The indoor temperature should be controlled between 21-29 degrees to promote rapid hatching of the silkworm eggs.

2. Feed mulberry leaves

Silkworms grow very fast and have a high demand for mulberry leaves. When raising silkworms, you need to prepare fresh, pesticide-free green mulberry leaves. Use a sharp knife to cut the mulberry leaves into small pieces, and then spread them on the box. Allow the silkworms to eat freely, and feed them mulberry leaves every 3-4 hours to ensure that there is enough food.

3. Suitable environment

Silkworms live in a clean environment. When raising silkworms, if the environment is too dirty, the silkworms will be infected with diseases. The boxes need to be cleaned every 2-3 days. The feces and leftover mulberry leaves in the boxes can be cleaned out, and the windows should be opened from morning to afternoon every day to ventilate the silkworms.

4. Feeding methods

When raising silkworms, the indoor temperature needs to be controlled at around 25 degrees, which is the optimal growth temperature. Silkworms of different ages like to eat different types of mulberry leaves. Silkworms aged 1-3 like to eat tenderer mulberry leaves, while silkworms aged 4-5 can be fed older mulberry leaves, which is beneficial for mulberry to absorb cellulose to spin silk and make cocoons.

5. 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.

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.
