CATDOLL : CATDOLL: How many days can silkworms survive without eating mulberry leaves?

1. How many days can silkworms survive without eating mulberry leaves?

Silkworms that do not eat mulberry leaves can live for three or four days. Silkworms that do not eat mulberry leaves will have the following problems:

If the silkworms are starved for too long, they will become dehydrated and die.

Specific solution:

You can find some substitutes, such as mulberry leaves, elm leaves, fig leaves, wormwood willow leaves, lettuce leaves, etc., and continue to feed mulberry leaves when mulberry leaves are available. Silkworms will likely starve to death if they do not eat food about 40 minutes after hatching.

Silkworm feeding notes:

The main feeding methods are as follows:

Because silkworms eat a lot of mulberry leaves, have a lot of excrement, and cannot tolerate high temperature and humidity, special attention should be paid to ventilation during the period. Silkworms should be raised with doors and windows open, and the food should be sparsely placed on each bed to ensure that the silkworms are well fed. During the three days of adult silkworms, each bed should have a sufficient area of ​​more than 400㎡, and sufficient mulberry leaves should be provided to ensure that the silkworms are well fed.

2. Why don’t silkworms eat mulberry leaves?

Question 1: What should I do if silkworms don’t eat mulberry leaves? The mulberry leaves that silkworms eat must be cut very thinly so that they can be eaten.

Question 2: Why don't silkworms eat mulberry leaves? The young silkworms eat mulberry leaves. Your silkworms are normal, don't worry.

I'll give you some suggestions

1. Now you need to feed it with tender mulberry leaves (it should be tender before it sheds its skin three times)

2. Chop the mulberry leaves into small pieces and feed them to the silkworms. The size of the cuts depends on how big your silkworms are. Cut them into cubes or strips that are twice the size of the silkworms. Don't feed too much at one time. The silkworms can't eat much and the dry mulberry leaves will easily roll up the silkworms. Then you will feed less and less.

3. Raise the silkworms separately, big ones with big ones and small ones with small ones

4. Stay away from pesticides, perfumes and cigarettes

5. Do not soak mulberry leaves in water or put them in plastic bags. Silkworms will get sick if they eat mulberry leaves that have rotted.

6. Raise silkworms sparsely. If they are too dense, they may scratch each other.

7. Do not catch the silkworms that have just hatched and molted. Wait 5-6 hours before feeding them mulberry leaves (use tender mulberry leaves this time). Feeding them too early will easily damage the mouthparts of the silkworms, causing them to develop slowly and grow smaller.

8. Don't put it under strong light. You need to turn it frequently. It tends to be phototropic or backlit. You can put it in the study or bedroom.

If you do the above points, your silkworms will be plump and white.

Question 3: Why do silkworms only eat mulberry leaves? The domestic silkworm is an important economic insect. The silkworm is a living machine that turns mulberry leaves into silk. The larval stage of silkworms is not very long, but they consume a large amount of fresh mulberry leaves. Why do silkworms love to eat mulberry leaves? First, let's take a look at mulberry leaves. Mulberry trees are tall trees that originally lived in humid and hot areas and were evergreen plants. Later, they were introduced to temperate zones and gradually became deciduous plants. There are mulberry trees in large areas of northern and southern my country. The leaves grow large and lush, and their fruits, mulberries, are a kind of fruit that people like to eat. Mulberry leaves, like the leaves of other plants, contain a variety of nutrients that are necessary for the growth and development of insects such as silkworms. In addition, various plant leaves have their own unique smells and tastes. These smells are emitted by chemicals in the leaves. Mulberry leaves have the smell of chlorophyll and chlorophyll. Insects such as silkworms rely on their sense of smell and taste to identify the smell of food. Silkworms do not only eat mulberry leaves. It is reported that more than 20 kinds of plant leaves, such as elm leaves, fig leaves, and lettuce leaves, are its food. However, in the long-term breeding practice, people learned that mulberry is the plant that is most likely to obtain a large number of leaves, so they have been feeding silkworms with mulberry leaves for a long time. After generations of eating mulberry leaves, silkworms gradually formed a special habit of eating mulberry leaves, and passed this habit on to their offspring. The offspring of silkworms rely on their keen sense of smell and taste organs to track the smell of alcohol and aldehydes emitted by mulberry leaves. Therefore, silkworms show the habit of eating mulberry leaves the most.

Question 4: Why do silkworms only eat mulberry leaves? Mulberry leaves are their staple food, but you can feed them medlar leaves, lettuce leaves, elm leaves, oak leaves, and lettuce leaves, but not too much. Silkworms can eat a lot of food, in addition to mulberry leaves, there are also elm leaves, fig leaves, wormwood leaves, dandelion leaves, lettuce leaves, lettuce leaves, ya leaf, salsify leaves, etc., no less than 20 kinds.

However, silkworms love to eat mulberry leaves the most. This is because silkworms spend the most time eating mulberry leaves. From generation to generation, they reproduce on mulberry trees, and gradually develop the habit of eating mulberry leaves, and it becomes hereditary.

A chemist once analyzed the smell of mulberry leaves. After distilling mulberry leaves at a high temperature of 132-157℃, he obtained an oily substance in a test tube, which looked like vinyl alcohol and vinyl aldehyde. This substance is volatile and smells like mint. If you drop it on paper, silkworms 30 cm away can smell it. After the silkworms smell this smell, they crawl over quickly. It can be seen that this is the most familiar signal smell for silkworms. Silkworms rely on their sense of smell and taste organs to identify the smell of mulberry leaves. If these sense of smell and taste organs are destroyed, they will not be able to distinguish the smell of mulberry leaves. Therefore, they will no longer be picky and will eat other leaves at will.

In recent years, the research on artificial feed for silkworms has basically found out the types of nutrients necessary for silkworm growth and their minimum requirements. It is also possible to feed silkworms artificial feed to raise silkworms, and it can also be colorful!

If you are raising silkworms, you should prepare more mulberry leaves instead of feeding them too many other leaves. You can put the mulberry leaves in a bag and put them in the refrigerator or in a well. This way you don't have to collect them often.

Question 5: Why don't silkworms eat mulberry leaves? They may be sleeping. The picture above is better.

Question 6: Is this mulberry leaf? Why don't silkworms eat it? Yes.

Question 7: Why don't silkworms move or eat mulberry leaves? Silkworms shed their skin four times. Each time they shed their skin, they grow bigger. The fifth time they look transparent, it means they are about to spin silk and become a silkworm. To shed their skin, they need to be dry and stay still, and they also don't eat mulberry leaves.

Question 8: What if silkworms don’t eat mulberry leaves? The mulberry leaves that silkworms eat must be cut very thinly so that they can be eaten.

3. What to do if the silkworms have no mulberry leaves to eat?

Silkworms don’t eat mulberry leaves, but they can eat the young shoots of elm trees and lettuce shoots. If that doesn’t work, buy silkworm feed online.

They can also eat lettuce leaves, mulberry leaves, paper mulberry leaves, elm leaves, duck onions, dandelions and lettuce leaves. Mulberry leaves are the most suitable natural food for silkworms.

The silkworm is a completely metamorphosed insect. In one generation, it goes through four different developmental stages: egg, larva, pupa and adult. Silkworm eggs are generally oval, slightly flat, with a slightly protruding end. They are composed of two parts: the eggshell and the egg contents. Eggs are the stage of embryogenesis and development into larvae. There are diapause eggs and non-diapause eggs. The silkworm larvae are oblong and cylindrical, consisting of three parts: head, thorax and abdomen. The first three segments are the thorax, and the last 10 segments are the abdomen. The larvae that have just hatched from the silkworm eggs look like ants and are called ant silkworms. Ant silkworms feed on mulberry leaves and continue to grow and develop. Their body color gradually changes from dark brown to bluish white. After a few days, they stop eating and moving, shed their old skin and put on new skin, which is called silkworm sleep.

From hatching to cocooning, silkworm larvae need to go through 4 moltings. The time between moltings is called an instar, so larvae generally go through 4 instars and 5 instars. Instars 1 to 3 are called young silkworms, and instars 4 to 5 are called mature silkworms. Under suitable temperature conditions, instar 1 is generally 3 to 4 days, instar 2 is about 3 days, instar 3 is 3 to 4 days, instar 4 is 4 to 5 days, instar 5 is 8 to 9 days, and the whole instar is about 25 days.

The staple food of silkworms is mulberry leaves, but you can feed them wolfberry leaves, lettuce leaves, elm leaves, oak leaves and lettuce leaves, but not too much. Silkworms can eat a lot of food, in addition to mulberry leaves, there are jujube leaves, elm leaves, fig leaves, wormwood leaves, dandelion leaves, lettuce leaves, romaine lettuce leaves, yam leaves, salsify leaves, etc., no less than twenty kinds.

However, silkworms love to eat mulberry leaves the most. This is because silkworms spend the most time eating mulberry leaves. From generation to generation, they reproduce on mulberry trees, and gradually develop the habit of eating mulberry leaves, and it becomes hereditary.

Silkworms can only grow and develop healthily and complete their generation alternation smoothly if they eat mulberry leaves.

If you are raising silkworms, you should prepare more mulberry leaves instead of feeding them too many other leaves. You can put the mulberry leaves in a bag and put them in the refrigerator or in a well, so you don't have to collect them often.

Eat lettuce leaves. I used to feed silkworms this and they grew very well.
