How to raise silkworm eggs? 5. How to raise silkworm eggs?

1. How to raise silkworm eggs.

Prepare a clean and odorless box, lay the silkworm eggs flat in it, and then place them in an environment of about 25, the silkworm eggs will gradually turn purple and black, and in about two weeks, the young silkworms can hatch.

2. How to take care of young silkworms.

The silkworm that has just hatched from the egg is black and covered with fine hair, like an ant, and is called "ant silkworm". The fine hairs on the body are no longer noticeable after a few days. Because the ant silkworms that come out are relatively small, it is best to put white paper underneath when hatching, so that it is easier to find.

The silkworm ant starts foraging about 40 minutes after it emerges, and we need to prepare relatively tender and clean mulberry leaves without water.

3. Silkworms need to be fed.

Silkworms like to eat mulberry leaves, and they need to prepare pesticide-free, clean and non-watery mulberry leaves. Do not use diseased leaves and rotten leaves. Don't touch it often when raising silkworms, and the silkworms may not eat or drink for a day when they are molting, so don't disturb them at this time.

Remove any food residues, leaves and faeces in a timely manner. Keep the overall living environment of silkworms clean. The box for raising silkworms should be placed in a ventilated and cool place.

The eggs of silkworms are relatively easy to hatch, mainly to control the temperature it needs, wait patiently for more than ten days, and generally have silkworms come out. Friends who are interested in silkworm farming can try it.

Put it in a cardboard box, or a small sieve for sieving rice, and if you use a sieve, put some paper on the bottom of the sieve. When the silkworm has just hatched from the egg, you should be especially careful with it, feed it with a relatively tender mulberry, and use a very soft brush to move it when changing mulberry leaves, and pay attention to the strength; Sometimes the mulberry leaves are too dry, and if you are not careful, you will leave the silkworms on the mulberry leaves to be discarded in the process of changing the mulberry. When you are young, it is difficult to raise a little, but it is easier to do when you grow up.

When it is about to form cocoons, take some wheat stalks and tie them into the shape of branches. After breaking the cocoon, put them together in a box, they will mate together, and then lay eggs. Sometimes because there are few silkworms raised, the moths will be left alone when the cocoon is broken, but don't worry, as long as a pair of silkworms is successful, I believe it will be enough for you to raise.

Mulberry leaves should be fresh, you can also collect a plastic bag at a time, use several sheets a day in parts, and sprinkle the rest with some water in the refrigerator to keep them fresh.

Put the silkworm eggs in the container and wait for hatching, the temperature should be controlled at about 25-28 degrees Celsius, the low temperature needs to be sealed in the container, after hatching, you need to feed with very tender mulberry leaves, generally seven days molt once, it will be motionless during the molting, so as not to affect its growth, 25 days later begin to form cocoons, and then it will become a moth, silkworms reproduce with eggs, look like fine sesame. ”

The spawning should be released, and the spawning should be placed in a clean and odorless box, and it should not be kept above 25 degrees.

Silkworm eggs are raised from the aspects of purchasing high-quality silkworm eggs, preparing suitable incubators, incubating silkworm eggs, putting hatched silkworm eggs on mulberry leaves, and controlling environmental factors.

1. Choose high-quality silkworm eggs: choose silkworm eggs with round appearance, uniform specifications, bright colors, high transparency, and no breakage and loss.

2. Prepare a suitable incubator: the size of the incubator and the material should be appropriate, and the temperature, humidity, ventilation and other conditions should also meet the standards required for silkworm egg incubation.

3. Carry out silkworm egg incubation: put the silkworm eggs into the incubator, keep the temperature and humidity appropriate, observe and inspect the travel god every day, deal with the dead silkworm eggs in time, and adjust the incubator environment to ensure that the silkworm eggs can hatch healthily.

4. Put the hatched silkworm eggs on mulberry leaves: by providing fresh mulberry leaves to the silkworm eggs, maintain suitable temperature, humidity and ventilation conditions to help the larvae hatch and grow smoothly.

5. Control environmental factors: the breeding of silkworm eggs requires room temperature of 20-28 and humidity of 65%-75%. At the same time, it is necessary to take care to prevent infection with viruses and bacteria, and to keep the environment clean and hygienic.

Silkworm eggs hatch into silkworm babies, and the steps of incubation are as follows:

Tools: box, silkworm plaque, black cloth, white paper, light, water.

1. First of all, prepare a small box as a silkworm room and disinfect it, and spread the silkworm baby in the silkworm plaque in the sterilized silkworm room, with the eggs facing up.

2. When the development reaches the later stage, when it is found that there are a small number of silkworm eggs with black spots, immediately cover the silkworm baby with a black cloth and do not see the light, about 40 hours after patting the grandson, remove the dark black cloth, wrap the silkworm baby in white paper, the egg is facing up, turn on the light and sensitize, so that the silkworm bites through the egg shell and hatches.

3. On the 1st to 4th day, the room temperature is required to be 24 degrees Celsius, and the difference between dry and wet is between degrees Celsius; The room temperature is required from day 5 to 10 to be 27 degrees Celsius, and the difference between dry and wet is between degrees Celsius.

In addition, it should be noted that the development temperature of the silkworm baby is 7-40, and some water should be sprinkled before hatching to keep the silkworm baby moist and maintain the temperature, but the water should not be too much, and it can be moistened.

Silkworm moth introduction

Silkworm moth is a kind of insect, native to China, domesticated and raised indoors, so it is also called silkworm; Silkworm raising and the use of silk is a major event in human life, which has been recorded in China about 4,000 years ago, and at least 3,000 years ago, China has begun to raise silkworms artificially; In 551 AD, two foreign monks brought cocoons to Europe.

The body of the moth is medium-sized, the antennae of both female and male are ctenoid, and the male has slightly longer ctenodonate; beak vestigial, lower lip whiskers short, no single eye, body wings grayish-white, wing veins grayish-brown; When the silkworm spins the silk cocoon, the head keeps swinging, weaving the silk into a neatly arranged zigzag silk circle, each weaving more than 20 silk circles, then move the position of the body, and then continue to spit and weave the silk row below, and then weave the other end after weaving.

Therefore, the cocoon of the silkworm is always thick at both ends and thin in the middle. Silkworms need to change their position 250 500 times for each cocoon, weaving more than 60,000 figure-8 silk rings, each silk circle is on average, and the silk length of a cocoon can reach 1500 3000m.
