Silkworms hatch fastest when their incubation environment has sufficient temperature and humidity.

Lay the silkworm seeds all flat inside the plaque, with the egg side always up. Place it inside a sterilized silkworm room. Generally, the room temperature should reach 24°C on the 1st-4th days, and the difference between dry and wet is 2-2.5°C. The room temperature should reach 27°C on the 5th-10th days, and the difference between dry and wet is 1.5-2°C. When the embryo develops to the late stage, and you find that there are a small number of eggs with greenish-colored dots, be sure to put the silkworm seeds in a black plaque immediately. immediately darken the silkworm seeds with a black cloth.

After 40 hours, that is, 4-5 hours before dawn on the 3rd day, you can remove the dark cloth, wrap the silkworm seeds in white paper, egg side up, turn on the light to sense the light, and let the ant silkworms bite through the eggshell and hatch out. The incubation and development of silkworm eggs at a temperature of 7-40 ° C, before hatching sprinkle some water to keep the silkworm seeds moist, the temperature can be.

How many stages of growth are there for baby silkworms?

1, silkworm eggs

The first stage of growth of silkworm babies is egg laying. Silkworm eggs appear round, small particles, just laid eggs appear transparent, at this time the eggs will be wrapped in paper towels, waiting for a period of time, the eggs will turn black, the larvae will hatch.

2, larvae

The second stage of the growth of silkworm babies is the larvae. The newly hatched larvae are black with fine hairs distributed all over the body. At this time, it is necessary to provide them with fresh mulberry leaves to replenish their nutrients, and after a week, the baby silkworms will turn white and begin to shed their skin. A larva total **** to molt four times to grow to maturity.

3, cocoon

The third stage of the growth of the baby silkworm is the cocoon. After four times the skin of the silkworm baby belongs to the fifth instar larvae, at this time the larvae have the ability to spit silk cocoon, will climb to the corner of the breeding box or artificially provide the area to spit silk, will wrap themselves in it.

4, adult

The fourth stage of the growth of baby silkworms is the adult. After the cocoon is made, wait for ten days, the pupa in the cocoon will break the cocoon and become an adult, at this time to cover the netting above the container to avoid the adult fly away, wait for one day, the adult will mate on its own, which will produce eggs and wait for the death of the silkworm.
