CATDOLL : CATDOLL: Is there a season for silkworm breeding? (Is there a season for silkworm breeding? Why?)

1. What is the season for raising silkworms?

Silkworms are usually raised in spring, around the Qingming Festival, when the temperature is relatively warm. If they are raised too early, the temperature will be too low and they will be frozen. In addition, the leaves of the mulberry tree have not grown much yet and cannot meet the needs of the silkworms.

2. What is the season for raising silkworms?

Spring and summer should be roughly the same as the growth cycle of mulberry trees 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.

3. Why are silkworms not born in autumn or winter?

Answer: Afraid of cold and grows slowly.

Silkworms are born in spring. The growth of silkworms usually lasts for 8 to 9 days. After going through five stages of larval stage, they enter the pupa stage, and then emerge as silk moths and break out of their cocoons.

After emerging from the cocoon, the female moth emits a smell from its tail to attract the male moth to mate. After mating, the male moth dies. The female moth can lay about five hundred eggs in about one night, and then slowly dies.

4. Can we still raise silkworms in summer, autumn or winter?

Yes. Silkworms can be raised all year round in the south, but not in the north. They can only be raised in the summer in the north because it is too cold in the north and mulberry trees cannot grow. Things to pay attention to when raising silkworms in summer and autumn: 1. Prevent pesticide poisoning. Do not spray organic pesticides such as insecticides in the silkworm room and farmland near the mulberry field during the silkworm raising season. The smell will cause poisoning to the silkworms; mulberry leaves must be tested and confirmed to be non-toxic before feeding silkworms. 2. Mosquito-repellent incense or mosquito repellents and insecticides are prohibited in the silkworm room. When used in a house near the silkworm room, the doors and windows of the silkworm room should also be closed to prevent poisoning of the silkworms. 3. Screen doors and windows should be installed in the silkworm room to prevent flies from entering the silkworm room and harming the silkworms, and "silkworm fly killing" emulsion should be added or sprayed on the silkworm body to kill fly maggots. 4. Before raising silkworms, rat holes should be blocked, and the silkworm racks should be kept at a certain distance from the walls. Lime powder or silkworm medicine should be sprinkled around the feet of the silkworm racks to prevent rats from climbing up. When raising ground silkworms, drugs should be used to kill rats. 5. In summer and autumn, the temperature for silkworm rearing is high. Doors and windows should be opened to strengthen indoor ventilation. Spraying mulberry leaves with clean water and using electric fans to blow breeze indoors are also conducive to cooling the room. 6. If sick silkworms are found, they should be cleaned up in time and put into a disinfection basin containing 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 number of pathogens. Do not spread them around the silkworm room for drying. They should be concentrated in the wild for retting or put in a manure pit for retting to prevent the spread of pathogens. 8. In summer and autumn, the temperature is high and the pathogens reproduce quickly. Pay attention to picking leaves on demand, transporting leaves in time, and storing leaves reasonably. The mulberry storage pool should be disinfected once for each age, and do not feed mulberry leaves overnight. 9. Do not feed wet leaves in hot and humid weather. Do not sprinkle water when storing 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.

Spring and summer should be roughly the same as the growth cycle of mulberry trees to ensure an adequate supply of mulberry leaves.

6. In which season are silkworms born?

To be honest, silkworms are usually born in April. There are mainly two situations. If they are dormant eggs, they need to wait until the second year to hatch. Of course, if they are non-detained eggs, they can hatch in April of the same year. If you want them to be produced that year, light and high temperature are very important. First, put the eggs in a paper box and keep the temperature at about 27 to 28 degrees, or you can put them under the light, but pay attention to the distance from the light, and also ensure the humidity.
