Anonymous users2024-02-14The time for silkworms to hatch is related to the temperature, and is not fixed, the temperature is 20-30, 9-11 days will hatch, the spring temperature is about 12, the incubation time is 22-27 days, if it is in the diapause period, the temperature is about 30, and the incubation time needs 30-100 days, so the surrounding temperature must be maintained during the incubation period in order to hatch as soon as possible.
How long does it take to hatch silkworms.
Spring silkworm to the end of the dead silk "silkworm here refers to an animal, can spin silk, spit out of the silk can be made into a variety of silk fabrics, more popular in the market, there are many places in our country that specialize in silkworm people, if you want to raise silkworms well, you need to know how to hatch silkworms, how long it takes to hatch silkworms.

Anonymous users2024-02-12The growth of silkworms is generally 8-9 days in the incubation period, about 25 days in the larval stage, and 14 days and 18 days in the pupal stage. The silkworm moth period is 3 days and 5 days.
The growth process of silkworms:
1. Silkworm egg hatching: After 8 9 days of green stimulation, the silkworm baby hatches from the silkworm egg, and the silkworm is black and small, commonly known as ant silkworm.
2. First instar: The color of the first instar silkworm changes from black to dark brown, and the mulberry eating time is 3 4 days, and the amount of food is not large. After entering the sleep period, the first molt will be carried out, and the sleep period will last 8 to 12 hours.
3. Second instar: the silkworm body grows significantly, the color becomes lighter, the mulberry eating time is about 3 days, and the sleep period is 8 12 hours.
4. Third instar: The color of the silkworm body changes to light brown, the amount of food begins to increase, and it enters the dormant period after about 4 days. 1 3 instar silkworms are generally called small silkworms, and enter the large silkworm stage after 10 to 14 hours.
5. Fourth instar: The silkworm that enters the large silkworm stage develops very quickly, and the amount of food increases significantly. The 4th instar time is generally 5 days, and the sleep period is very long, generally called the large sleep period, and the sleep period can reach 30 to 40 hours.
6. Fifth instar: the period when mulberry cannibalizes the largest amount of leaves, and the amount of leaves eaten in about 7 days accounts for more than 75% of the total leaf eat. After 7 days, the silkworm body begins to shorten and become brighter, commonly known as the mature silkworm, the mature silkworm no longer eats, and begins to spin silk and form cocoons.
