Some animals that live in nature can be used to meet the needs of human life, one of which is silkworms. Silkworms have the characteristics of being able to produce silk threads of high selling value. Silk threads are taken from larvae that have not yet hatched. Would You Know How Much “Weight of Average Silkworm” and “How Fast Can a Domestic Silkmoth Run”
What are silkworms?
A silkworm is a moth whose larvae sing a large Number of strong silk in Constructing Its Own cocoon mainly: an Asian moth (Bombyx mori from the family Bombycidae) whose coarsely hairless caterpillar produces trade silk.
Worms are often found in wet areas and there is a lot of soil and plants. Do You Know Just How Much”Weight Of Typical Worm” Know about it?
What does a silkworm look like?
Not much different from other types of moths, silkworm moths, in general, have a body shape that tends to be long and bumpy with brownish-white feathers enveloping their bodies.
How long does a silkworm moth live?
Moths live very shortly 5-10 days, with males generally outlive females. The silk moth will begin to look for a mate as soon as it comes out of its cocoon, with some seen mating with the moth of the opposite sex inside its cocoon if two moths share one!
Can you know the exact order of the life cycle of silkworms?
The entire life span of silkworms starts with silk moths. Inside the silkworm (caterpillar) turns into a pupa and then becomes a moth and the moth develops perfectly out of the cocoon.
So the order is silk moth —> eggs —> silkworms —> cocoons.
Would You Know How Much “Weight of Average Silkworm” and “How Fast Can a Domestic Silkmoth Run”
The average weight of Chinese silkworms is 0.9023 grams and is included in the quality of class D (≤ 0.9 grams).
The stages of production in sericulture are as follows:
- Silk moths lay eggs.
- If the eggs hatch, the caterpillars are fed mulberry leaves.
- When silk moths are about 25 days old, they weigh 10,000 times heavier than when they hatch. They are now ready to spin silk cocoons.
- Silk is produced in two glands on the moth’s head and then forced out in liquid form through openings called spinners or “spinnerets”.
- Silk will harden due to contact with air.
- The moth rotates about 1 mile in filaments and completely wraps itself in a cocoon for about two or three days but due to quality restrictions, the amount of silk cocoon that can be used is very small. Approximately 5500 silk moths are needed to produce 1 kg of silk.
- Silk obtained from the cocoon is not damaged as a result of the brush by finding the outer end of the filament.
- The silk filament is then wound up in a reel. One cocoon contains about 1,000 meters of silk filaments. Silk at this phase is called raw silk. Only one thread consists of 48 individual silk filaments. This could result in at least 4,000 meters throughout the.
- Threads can now be formed by combining several silk threads.
Types, Characteristics, and Characteristics of SilkWorms
Then the Characteristics and Characteristics of SilkWorms? Based on race, it turns out that the type of silkworm (Bombyx mori L.) is divided into 4 types of races, namely:
This Japanese-breed silkworm turns out to lay many eggs with a long life cycle. The shape of the body is small, and the cocoon is yellow or green and notched in the middle.
Caterpillars of this Chinese breed turned out to be sensitive to high humidity. Kokon that he has turned out to be white, pink, greenish, and yellow gold corner. The silk fibers produced are smooth and very easy to spin.
European breed silkworms
Caterpillars and eggs of this breed are large with a long life cycle. His cocoon is also large with a slight curve in the middle. The color of the is white or reddish with its long silk fibers.
Tropical silkworms as the name suggests, live in the Tropics and are resistant to hot temperatures, and have a small size.
The following are the characteristics of Japanese breed silkworms, among others:
- Relatively longer production life compared to Chinese breeds
- Weaker, so these silkworms are more susceptible to disease attacks
- The shape of it has is like peanuts
Characteristics of Chinese breed silkworms include:
- Relatively shorter production life
- The shape is round
- Their resistance to disease is better
Facts of silkworms
Silkworm turns out to have some interesting uniqueness to read. Here are some unique facts about silkworms producing high-value soft fabrics.
Historically, silk has been found since the 27th century BC in China during the Huang Ti (Yellow Emperor) empire.
The emperor’s empress accidentally noticed a silkworm cocoon falling into her tea that turned into a strand of a fine, long thread. Then the empress ordered that the cocoon be made into cloth.
China and India make wild silkworms as one of the animals cultivated as a producer of silk fabrics for export commodities.
Silkworms are voracious animals that eat. These caterpillars will eat every day as long as food supplies are still around.
At the age of 25 days, due to its gluttony, the weight of silkworms increased 10 thousand times since hatching.
Mulberry silk is very popular, so it becomes a synonym for the word silk itself. Mulberry silk fabric is produced from mulberry silkworm (Bombyx moir L.).
The name mulberry is taken from the name of the leaf given for the food of this caterpillar, which is a leaf derived from the Mulberry tree.
Ants are very dangerous animals for silkworms. Ants can interfere with and thwart the cultivation of wild silkworms, so it is necessary to avoid silkworms from such animals.
The trick is to paint the trunk of the tree with a liquid limestone one meter high from the ground so that the ants can not crawl up to the tree.
Wild silkworms take 43 to 58 days for each one life cycle. A female can produce as many as 30 thousand eggs per head.
One hectare of mulberry plantations will produce 11 tons of mulberry leaves for silkworm food and will produce about 225 kilograms of cocoons. The result is only 42.5 kilograms of silk thread.
Silus live silkworms starting from eggs, larvae, pupae (encased in coons), and butterflies. Eggs will become caterpillars and will hatch into caterpillar larvae in about two weeks. while the process from caterpillars to pupae after the age of 25 days.
In one egg-laying, a female silkworm will produce 400 needle-headed eggs. After the mouth, the female silkworm then dies.
Normally. a silkworm will be able to produce silk fibers up to 15 meters in length every minute.
A cocoon of silkworms, when the strands are stretched will stretch 900 meters long strands of silk thread. A piece of silk was once recorded as having a length of about 4,000 meters.
