How long does it take to go from ant silkworm to second instar silkworm?????

How long does it take to go from the ants to the shedding.

It was black and blank, and the inside of Gargowu County went in.

Ant silkworms can become 1st instar silkworms from hatching from eggs. The silkworm baby that has just hatched from the egg is black like an ant, and people call it "ant silkworm", which is called a first-year silkworm at this time, and the body is covered with fine hair, and the hair is not obvious after about a few days. Silkworm ants have an appetite about 40 minutes after hatching, and the feeding process begins at this time.

The growth process of ant silkwormsThe silkworm baby lives on mulberry leaves, and after eating mulberry leaves, her body turns white, and after a while, she begins to shed her skin. Silkworms do not eat or move when they sleep, on the surface they sleep, but in fact they take off their old skins and put on new skins to continue to grow. The silkworm baby should molt 4 times during the whole feeding process, and every time it molts, it will not eat or move, so try not to disturb it at this time, and do not throw it away if it is sick.

The silkworm sleeps for about a day at a time.

1. Silkworm egg hatching: After 8-9 days of green incubation, silkworm babies hatch out of silkworm eggs, and the silkworms are black and small, commonly known as ant silkworms.

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 skin will be molted for the first time, and the sleep period will last 8-12 hours.

3. Second instar: the silkworm body grows significantly, the color becomes lighter, the mulberry eating time is about 3 days, and the sleeping 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-year-old 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 known as the large sleep period, and the sleep period can reach 30-40 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.

The 5th-10th day requires room temperature 27, dry and wet difference. When the embryo develops to the late stage, it is found that there are a small number of silkworm eggs with small blue dots, immediately darken the silkworm seed with a black cloth, after about 40 hours, that is, 4-5 o'clock before dawn on the third day, remove the dark black cloth, wrap the silkworm seed in white paper, the egg is facing up, turn on the light and sensitize, so that the ant silkworm bites through the egg shell and hatches.

1. Incubation of silkworm eggs: After 8-9 days of incubation, the young silkworms hatch from the silkworm eggs, and the newly feathered silkworms are black and small, commonly known as ant silkworms. 2.

First-in-star: The color of the first-in-star silkworm changes from black to dark brown, and it eats mulberry for 3-4 days, and the amount of food is not large. After entering the sleep phase, the skin will molt for the first time, and the sleep period will last for 8-12 hours.

3.Second instar: The silkworm body grows obviously, and the color becomes lighter.

The feeding time is about 3 days, and the sleep period is 8-12 hours. 1. Incubation of silkworm eggs: After 8-9 days of incubation, young silkworms hatch out of silkworm eggs, and the newly feathered silkworm body is black and small, commonly known as ant silkworms.

2. First-year-old: The body color of first-year-old silkworms changes from black to dark brown to sell royal things, and it takes 3-4 days to eat mulberry, and the amount of food is small. After entering the sleep phase, the skin will molt for the first time, and the sleep period will last for 8-12 hours.

3. Second instar: the silkworm body grows obviously, and the color becomes lighter. The feeding time is about 3 days, and the sleep time is 8-12 hours.

4. Three-instar hailstorm: The silkworm body turns light brown, the amount of food begins to increase, and it enters the liquid period of sleep in about 4 days. 1 10-year-old silkworms are generally called small silkworms, and enter the large silkworm stage after 10 14 hours.

5. Fourth instar: The silkworm that enters the large silkworm stage develops rapidly, and the amount of food increases significantly. The fourth instar generally lasts for 5 days, and the sleep period is very long, generally called the large sleep period, and the sleep period can reach 30-40 hours of age

During the period when mulberry eats the largest amount of leaves, the amount of leaves eaten in about 7 days accounts for more than 75% of the total amount of leaves. After 7 days, the silkworm body begins to become shorter and brighter, commonly known as adult silkworm. When the mature silkworm stops eating, it begins to spin silk and form cocoons.

In about two weeks, the larvae hatch. Silkworm eggs are generally kept in the refrigerator, and placed at room temperature after being removed, the most suitable temperature for silkworm eggs to hatch is about room temperature 25, and silkworm eggs will gradually turn purple-black. The outer layer of the silkworm egg is a hard egg shell, and the inside is the yolk and serous membrane, and the embryo in the fertilized egg continuously ingests nutrients during the development process, and gradually develops into an ant silkworm, which crawls out of the egg shell, and the egg shell becomes white or light yellow after the egg shell is empty.

When the silkworm hatches from the silkworm egg, the color of the body is brown or black, very small, and there are many fine hairs, and it looks a bit like an ant, so it is called ant silkworm. The antworm is about 2 mm long and about 2 mm wide, and after crawling out of the egg shell, it will eat mulberry leaves after 2 to 3 hours.

How long does it take for freshly laid silkworm eggs to hatch.

Silkworm eggs are generally kept in the refrigerator, taken out and placed at room temperature, the most suitable temperature for silkworm eggs to hatch is about room temperature 25, silkworm eggs will gradually turn purple black, about two weeks or so, you can hatch larvae.

It can be bred for 2 generations under the conditions of factory rearing in the south.

Dear, it's an honor to answer your questions Silkworm is a kind of insect, in its life cycle, the larval stage is divided into five instars, and it takes a certain amount of time from the first instar to the second instar of the reed. Generally speaking, the eggs of silkworms hatch out of pupa and collapse into first-instar silkworms, and after about 4-5 days of development, they will enter the second instar stage. However, the specific time will be affected by environmental factors (such as temperature, humidity) and different varieties, so this time may have a certain deviation.

Under normal circumstances, if suitable temperature, humidity and other conditions are provided, it generally takes 3-4 days for the silkworm to complete the first molt and become a second-instar silkworm. At this time, the body color of the silkworm gradually becomes darker, the body length is longer than that of the first-instar bond, and the amount of food gradually increases. If there is severe stress or disease during the breeding process, their growth rate may be slowed down or abnormal, in this case, it is necessary to take timely measures to prevent the death of silkworms.
