What happens to silkworms after they lay eggs? How long after laying eggs can a silkworm hatch

In planting good mulberry leaves.

On the basis of preparing the silkworm room and silkworm tools; 7 days before raising silkworms, spray and disinfect with 1% strong chlorine, half a kilogram of medicinal solution per square meter, seal for more than 24 hours after spraying, and at the same time, spray the surrounding environment of the silkworm house should be sprayed and disinfected. About the eighth day of silkworm seed out of the warehouse, you can see that there is a small black spot at one end of the silkworm egg, called point green, a silkworm seed has 20% of the eggs point green, use the black cloth to shade the light, from the day of the point of green, the black cloth will be removed at 5 o'clock in the morning of the third day, and the light will be turned on to incubate.

Photosensitive 3 to 4 hours later, spring silkworms.

At 9 a.m., the summer and autumn silkworms can harvest ants at 7 or 8 a.m. Method of collecting ants: use mulberry trees.

The first leaf is cut into centimeter cubes, about 5 times the amount of the ant, and sprinkled on a dustpan lined with plastic film.

On the silkworm seed paper in one hand and the silkworm chopsticks in the other hand, evenly pat the back of the silkworm seed paper to make the ant silkworm fall on the dustpan, and then scrape the ant silkworm with goose feathers and arrange it into a circle.

If you want to hatch, wrap the cocoons in a clean napkin and place them in a place where they won't be flattened, either in an empty box or in a drawer. At the beginning of April next year, you have to pay attention to whether there are any small black insects crawling out, that is, silkworms. You can use the tip of a brush to pick the silkworms off the cocoon and put them in a clean and dry box to continue raising.

It must not be placed in the refrigerator, because hatching requires a certain temperature, and the suitable temperature is generally about 25, and the silkworms cannot hatch if it is too cold. If you forget it in the refrigerator, then you won't have silkworms to raise next year.

Other people's storage method in the refrigerator is to raise it in batches, if you are a normal way to raise it, just store it in a warm and dry environment.

Don't let the moth lay its eggs on the cocoon After the moth breaks the pupa and takes out the cocoon Lay a piece of cardpaper After they lay the eggs Cut out the paper with the eggs and seal it in a sealed bag and put it in the refrigerator The next year to hatch again I tried to hatch a few.

Is the cocoon dry, if the cocoon is dry, just find an iron box and put it, don't put it in a place with high temperature, and prevent freezing to death in winter.

If it's not specially kept, don't ask for it, such silkworm eggs are unstable, if you want to steam it with sulfur without letting it come out of the eggs, you can experiment with a little bit.

Generally, the egg period of silkworms is 15-30 days, which means that it takes about 15-30 days for silkworms to hatch from the eggs. Silkworm eggs are generally kept in the refrigerator, put at room temperature after taking out the morning beam, the temperature suitable for the hatching of silkworm eggs is about room temperature 25, silkworm eggs will gradually become purple and black, open for about two weeks, you can hatch out of Zhiyun larvae.

After the eggs of silkworms are laid, they need to pass a certain amount of time before they can hatch. Generally speaking, the incubation time of silkworm eggs is about 7-10 days. 2.

Incubation conditions: The incubation of silkworm eggs requires certain temperature and humidity conditions. Generally speaking, a temperature between 25-30 and a humidity of 70-80% is more suitable.

3.Hatching chain family environment: The hatching of silkworm eggs requires a clean, hygienic and well-ventilated environment.

In short, silkworms can still hatch in the same year after laying eggs, but it is necessary to pay attention to maintaining suitable incubation conditions to ensure that silkworm eggs can hatch smoothly and healthy silkworm seeds.

Hello dear, happy to answer your <>

Silkworm cavity can hatch seed silkworms when laying eggs, or it can be stored and re-hatched in the following year. During egg laying, the silkworm mother lays her eggs on a surface such as cardboard or bamboo chips, and then stops laying eggs. At this time, the eggs have good vigor and can hatch seed silkworms in time.

In the breeding process, the breeding of varieties, the health and quality of female silkworms will also affect the survival rate of eggs and the quality of incubation and scarcity. Generally speaking, high-quality silkworms can be obtained by hatching silkworm eggs with an egg-laying period of about half a month. If the eggs need to be preserved until the following year before hatching, special treatment is required to make the eggs dormant to prevent them from drying out, dying or hatching unevenly.

There are various ways to preserve eggs, such as closed storage, refrigerated storage, or dry storage. However, it should be noted that the long-term preservation time will affect the hatchability and quality of eggs, and there may also be bacterial contamination and parasite hazards, which will affect the efficiency of silkworm farming. Therefore, when preserving eggs, it is necessary to pay attention to maintaining the humidity and temperature of the eggs, and the cycle should not be too long.

<> "Hello friend, after the silkworm lays eggs, the eggs need to hatch into larvae, and then the larvae continue to molt and develop into mature silkworms before they have the ability to lay eggs. Generally speaking, silkworms can still hatch and cover the land in the year after laying eggs, but the following aspects need to be noted:1

Incubation environment: Silkworm eggs are most suitable for hatching in a ring with a humidity of about 80% at 20-30 and a humidity of about 80%, and it is also necessary to maintain ventilation to avoid the death of silkworm eggs caused by insufficient oxygen or too much carbon dioxide. 2.

Nutrition and feed: The larvae that hatch silkworm eggs need to be well fed with nutrients and suitable feed to ensure healthy growth and maturation. In conclusion, there is still the possibility of hatching in the year after the silkworm lays eggs, but it is necessary to pay attention to factors such as the incubation environment, incubation time, nutrition and feed.
