How long does a silkworm live, and how many days does a silkworm live in total

Silkworm eggs hatch into ant silkworms in about 10 days, ant silkworms to pupate about 20 days, pupa to silkworm moths about 14 days, counting more than 40 days of life, I mean mulberry silkworms.

If the silkworm comes out of the egg and dies, it is generally more than 50 days.

Some teachers also say 53 days, but it is generally not so accurate, and it has a lot to do with the temperature and food.

The first half of life: the silkworm has to go through four stages of development in its generation: egg, larva (silkworm), pupa, and adult (moth). Silkworms reproduce from eggs, and new organisms are formed inside the eggs.

The larvae that form inside the eggs bite through the egg shell and hatch. The larvae that have just emerged from the egg shell have a small body, are black-brown, and the whole body is full of bristles, and the shape is like an ant, which is called ant silkworm. The ant silkworm grows rapidly with the mulberry eating, the middle part becomes green, the bristles become thin, called the hair thinning stage, and then the body drive increases, and the body color gradually fades and turns blue-white.

Since the capacity of the larval epidermis is limited, when it grows to a certain extent, it is necessary to remove the old skin and replace it with a slightly wider new skin in order to grow. After 3 or 4 days of ant collection, the larvae stop eating mulberry, spin silk, fix the gastropod and tail foot on the silkworm seat, and no longer crawl, which is called sleep. After a day and night, the sleeping silkworm takes off its old skin and puts on a new skin.

The silkworm that has just shed its old skin is called a silkworm. After eating mulberry, it continues to grow, and when it reaches a certain level, it sleeps and peels off again. In general, varieties sleep 4 times and shed skin 4 times during the larval period, that is, 4 sleeps and 5 instars.

The first age is from hatching to the end of the first sleep; The second age is fed from the first sleep to the end of the second sleep; The third age is fed from the second sleep to the end of the third sleep; The fourth age is fed from the third sleep to the end of the fourth sleep; The fifth age is fed from the fourth sleep to the old and mature. At the end of the fifth instar, the front half of the body is translucent, stop eating mulberry, raise the head and chest to sway left and right, and spit silk wisps in the mouth, which is called mature silkworm at this time. Mature silkworms spin silk cocoons, and the larvae end here, generally after 25 to 28 days.

Due to different varieties and different temperatures, the length of the whole age is different.

About a month - two months.

There shouldn't be so many days, it seems like 56 days.

The life of a silkworm needs to go through five stages: silkworm egg, ant silkworm, mature silkworm, silkworm cocoon, silkworm moth, and the life span is about 50 days. The growth and development of silkworms is related to temperature, humidity and food, and the general greening period is about 10-11 days, and the larval stage is divided into five instar shelters, which are 4-5 days for the first instar, 3-4 days for the second instar, 4 days for the third instar, 6 days for the fourth instar, and 7-9 days for the fifth instar, a total of about 25 days.

The silkworm pupal stage is generally 14-15 days, and the moth rot and clearing period is generally 3-5 days.

The silkworm moth no longer eats after feathering, and after about an hour the wings become stiff and then mate with the tail. Each female lays about 500 eggs. Then it dies slowly, so the life cycle of silkworms is about 2-3 months.

The silkworm pupal stage is generally 14-15 days, and the moth stage is generally 3-5 days.

The silkworm moth no longer eats after feathering, and after about an hour the wings will harden, and the good finch will then mate. Each female lays about 500 eggs. Then it dies slowly, so the life cycle of the silkworm is about 2-3 months.

Summary. Hello! We're happy to answer for you!

The life of a parent silkworm is generally about 56 days, and the cycle of a silkworm is about 24 to 32 days. The larval stage of silkworms is about 25 days, a total of four times of peeling, each peeling is an increase of one year, followed by the pupal stage of silkworms, the whole process needs to last 14 18 days, and finally the adult stage, when the silkworm pupa moth, can live for 3 5 days.

Hello! I'm glad to answer your answer! The life of a parent silkworm is generally about 56 days, and the cycle of a silkworm is about 24 to 32 days.

The larval stage of silkworms is about 25 days, a total of silver needs to be done to go through four times of peeling, each peeling is even an increase of one year, followed by the pupal period of silkworms, the whole process needs to last 14 18 days, and finally the adult stage, when the silkworm pupa moth, can live for 3 5 days.

Extended content: Precautions for the front of silkworm raising1Pay attention to temperature regulationThe silkworm itself is afraid of cold, so the temperature should be strictly controlled when raising silkworms, and the ambient temperature of the silkworm stage is controlled at around 27 degrees, and the ambient temperature at the stage of the silkworm is controlled at around 25 degrees.

2.Pay attention to the preparation of food, silkworms mainly feed on mulberry leaves, orange farmers need to prepare fresh mulberry leaves, do a good job of cleaning, but also to ensure that mulberry leaves have no pesticide residues.
