How to raise silkworms? What do you do after cocooning?

Bombyx mori is an insect of the family Lepidoptera, which is the main raw material source of silk. Sericulture has a long history in China. Because of its high profit value, there are actually many people raising silkworms up to now, so some old sericulturists have made good profits. So how to raise silkworms? What do you do after cocooning?

I. breeding methods of silkworms

1. Silkworm box management

Sericulture is generally raised in boxes, which is not only conducive to management, but also conducive to the growth of silkworms, considering the fragility of silkworms, first of all, silkworm boxes must be disinfected in place, and it is best to use the sun for a few days after disinfection to achieve the effect of natural disinfection. secondly, do not choose a material with strong water absorption, silkworms like a relatively dry environment, and secondly, the position of the silkworm box should not be in a place where the light is too bright, which is not conducive to the growth of silkworms.

two。 Feeding and management

The mulberry leaves fed by sericulture in each time period are also different. Special attention should be paid to the fact that in order to ensure the initial development, the early mulberry leaves must be relatively fresh and tender, and silkworms do not need water when they are fed, and all their water sources come from mulberry leaves. So every time, the mulberry leaves are fed as fresh as possible, and the water in the leaves should be kept clean. The feeding time is usually from 7 a.m. to 10:00, with 4-5 times in the middle. Mulberry leaves must be covered on the silkworm body, which is conducive to eating, and the thickness is generally about 3-4 layers of mulberry leaves.

3. Environment management

Silkworms are sensitive to light and temperature. In the early stage, young silkworms generally avoid light exposure. When there is light, they hatch slowly, the temperature is controlled at about 25-30 ℃, and the temperature is kept at about 30-33 ℃ at the initial stage after hatching. At this time, the control of light can be loosened a little bit, but try to avoid continuous bright light. In the middle and later stages, the temperature should be controlled at about 25 ℃. At this time, the environment can be kept bright occasionally, but it is still mainly dark.

4. Matters needing attention

Silkworms are very fragile, once diarrhea occurs, it is a very serious problem for silkworms. It is necessary to isolate them in time to avoid more effects, followed by the cleaning of feces. In order to avoid the damage to silkworms during cleaning, it is recommended that the cleaning times should not be too much. Generally, when silkworm feces accumulate too deeply, the remaining stems of mulberry leaves must be cleaned in time to avoid harm to silkworms. Finally, the environment for sericulture must be relatively ventilated to avoid being too muggy.

What to do with silkworm after cocooning

After cocooning, the silkworm will molt and pupate in the cocoon, break the cocoon in 8 to 10 days, and die naturally in a week after mating and laying eggs. Therefore, after cocooning, the silkworm can spread a piece of white paper at the bottom of the clean cardboard box without peculiar smell. The cocoon is also covered with a layer of white paper. If the cocoon is put in the box, the cocoon-breaking moth will mate, and the female moth lays eggs on paper. In silk production, if the pupa is allowed to metamorphosis into an adult. If the cocoon is dissolved and drilled naturally, because the cocoon is broken, the silk thread will become shorter and cannot be used for spinning and weaving silk, so the cocoon should be put into boiling water to kill the pupa before it is broken, making it easy to disassemble.

The above is the introduction of the breeding methods of silkworms and the treatment after cocooning. Sericulture is indeed a culture project that pays attention to management, so you must pay more attention to it every day. Once something happens, it is easy to cause a chain reaction. Bombyx mori is an oligophagous insect. In addition to eating mulberry leaves, it can also eat lettuce leaves, oyster leaves, elm leaves, duck onions, dandelion and lettuce leaves. Mulberry leaves are the most suitable natural food for silkworms.
