CATDOLL : CATDOLL: What is the new technology of raising silkworms with Artemisia selengensis (pictures of raising silkworms with Artemisia selengensis)

1. In what kind of environment do silkworms generally grow? Do they eat the same food at different stages? If not, what are they?

Silkworms can be divided into several types, including mulberry silkworms, tussah silkworms, natural silkworms and amber silkworms. Different types of silkworms eat different things.

1. Mulberry silkworms are oligophagous insects. In addition to mulberry leaves, they can also eat lettuce leaves, mulberry leaves, paper mulberry leaves, elm leaves, duck chives, dandelions and lettuce leaves. Mulberry leaves are the most suitable natural food for silkworms.

2. Tussah silkworms feed on the leaves of plants of the genus Quercus in the Fagaceae family, such as Quercus oxyphylla, Quercus mongolica, and Quercus truncatula. They can also eat the leaves of plants such as Artemisia selengensis, Salix babylonica, chestnut, maple, pear, and apple.

3. The silkworm feeds on the leaves of plants of the genus Quercus in the Fagaceae family, such as the Liaodong Quercus, Mongolian Quercus, Shuanpi Quercus, and pointed Quercus. The amber silkworm can eat the leaves of several plants, mainly the leaves of nanmu, and also the leaves of evergreen trees such as Rubiaceae and Tiger Thorn, as well as the leaves of plants such as Michelia and Cinnamomum. Extended information: 1. Mulberry silkworm: Mulberry silkworm feeds on mulberry leaves, and cocoons can be reeled into silk. Silk is a precious textile raw material, mainly used for weaving silk, and is also widely used in military industry, electrical engineering, etc. Pupae, moths, and silkworm feces can also be used comprehensively. 2. Tussah silkworm: Tussah silkworm is named because it likes to eat tussah leaves. Cocoons can be reeled into silk, which is mainly used to weave tussah silk. Pupae can be eaten and used as medicinal materials. It occurs twice a year, and adults appear from April to June, and overwinter as pupae in cocoons. 3. Cecropia: Cecropia is a silk-spinning insect of the family Bombyx mori in the order Lepidoptera. It is a very rare species in nature. The Cecropia silk it produces is a priceless treasure, known as a green soft gem that is better than gold.

4. Camphor silkworm: Camphor silkworm is a wild silk-spinning insect of the Bombyx mori family of the Lepidoptera order. Its silk can be made into silkworm gut thread and high-quality fishing line. It is commonly found in Guangdong, Taiwan, Guangxi, Fujian, Jiangxi, Hunan and other places in my country.

5. Chestnut silkworm: The chestnut silkworm is an economic insect that spins silk and cocoons and feeds mainly on walnut leaves and chestnut leaves. It is widely distributed in Japan, my country's "Three Norths" and central and southern regions. Chestnut silk is an expensive natural fiber.

6. Ailanthus annuus: Ailanthus annuus is an economic insect that spins silk and makes cocoons, and its staple food is Ailanthus annuus leaves (Ailanthus toonae), and its sidekicks include leaves of Tung oil tree, castor bean, holly, Michelia, Paulownia, Sycamore, and Cinnamomum camphora. It belongs to the Bombyx mori family of the order Lepidoptera, and is found in China, Japan, India and other countries.

7. Willow silkworm: Willow silkworm mainly feeds on leaves of maple poplar, snow willow, Chinese tallow tree, camptotheca acuminata, apple, pear, etc. It is a silk-producing insect. High-quality cocoons can produce 300 meters of silk, which is thin and resistant to decay. It is mainly distributed in East Asia and Southeast Asia.

8. Tiger silkworm: The tiger silkworm is a kind of silkworm. There are black and white stripes on the body of the silkworm in the larval stage. The moth stage is not much different from the ordinary white silkworm. The larval stage likes to eat mulberry plants, especially mulberry leaves. The silkworm cocoons are an important raw material for the textile industry.

2. How long does it take for silkworms to hatch?

It takes about 15-30 days for silkworms to hatch from eggs.

Silkworm eggs: Silkworms reproduce by eggs. Silkworm eggs look like fine sesame seeds, about 1 mm wide and 0.5 mm thick. A female moth can lay 400 to 500 silkworm eggs. 1700 to 2000 silkworm eggs weigh about 1 gram and have a diameter of 0.2 cm.

The color of silkworm eggs is light yellow or yellow when they are just laid. After 1 to 2 days, they turn into light adzuki bean color or adzuki bean color. After 3 to 4 days, they turn into gray-green or purple. They no longer change and are called fixed color.

The outer layer of the silkworm egg is a hard eggshell, and inside is yolk and serous membrane. The embryo in the fertilized egg continuously absorbs nutrients during the development process and gradually develops into a silkworm. It crawls out of the eggshell, and the eggshell becomes white or light yellow after it is empty.

The first instar is four to five days; the second instar is three to four days; the third instar is four days; the fourth instar is six days; the fifth instar is seven to nine days; the pupal stage is fourteen to eighteen days; and the moth stage is three to five days.

Type Introduction

silkworm

Also known as the silkworm, it is one of the economic insects that feed on mulberry leaves and spin silk cocoons. It belongs to the Lepidoptera, Bombycidae, and its scientific name is Bombyx mori. The silkworm originated in China. Its growth temperature is 7-40℃, and its optimal breeding temperature is 20-25℃. It is mainly distributed in temperate, subtropical and tropical regions.

Silkworms are oligophagous insects. In addition to mulberry leaves, they can also eat lettuce leaves, mulberry leaves, paper mulberry leaves, elm leaves, duck chives, dandelions and lettuce leaves. Mulberry leaves are the most suitable natural food for silkworms.

Silkworms are holometabolous insects, and they go through four completely different developmental stages in their life: egg, larva, pupa, and adult. Under suitable temperature conditions, it takes 22 to 26 days for the larvae to hatch and spin cocoons. A silkworm eats about 20 to 25 grams of mulberry leaves in its lifetime, and generally undergoes four dormancy and molting. When it reaches the extreme growth stage, its weight increases by about 10,000 times.

The amount of mulberry leaves consumed by the last instar accounts for more than 85% of the total amount of mulberry leaves consumed. The cocoons made by silkworms can be used to reel silk, which is an excellent textile fiber and the raw material of silk. The pupae of silkworms are edible, and silkworm moths and silkworm feces can be used comprehensively as raw materials for various chemical and pharmaceutical industries. Silkworm sand pillows have the effects of dispelling wind and dampness, strengthening the brain and improving eyesight.

According to the production situation in 2006, there are eight major silkworm-raising provinces in my country, namely Guangxi, Jiangsu, Zhejiang, Sichuan, Shandong, Guangdong, Chongqing, Anhui, etc., and their cocoon production accounts for about 86% of the national total; the secondary silkworm-raising provinces include Yunnan, Shaanxi, Hubei, Jiangxi, Henan, Shanxi, Hunan and other seven provinces, and their cocoon production accounts for 13.64% of the national total.

Tussah

The tussah silkworm is an insect that spins silk and spins cocoons and feeds on tussah leaves. It belongs to the order Lepidoptera, family Bombyx mori, and its scientific name is Antheraea pernyi. It is native to China, and its growth temperature is 8-30℃, its optimum growth temperature is 11-25℃, and its most suitable temperature is 22-24℃. It is mainly distributed in China. It is also distributed in small quantities in North Korea, South Korea, Russia, Ukraine, India, Japan and other countries.

The silkworm feeds on the leaves of plants of the genus Quercus, such as Quercus mongolica, Quercus truncatula, etc., and can also eat the leaves of Artemisia selengensis, Atractylodes lanceolata, Chestnut, Maple, Pear, Apple, etc. The silkworm is a completely metamorphosed insect, and it goes through four developmental stages in its life: egg, larva, pupa, and adult, which have completely different morphologies and physiological functions.

After four dormancy and molting, the silkworm ages one year after each molting. It takes about 50 days for a silkworm to hatch and mature into a cocoon at the age of 5. Spring silkworms eat about 30 to 35 grams of leaves in their lifetime, while autumn silkworms eat 50 to 58 grams of leaves. The leaves eaten by adult silkworms account for more than 80% of the total amount of leaves eaten. The weight of spring silkworms is 14 grams, while that of autumn silkworms is about 21 grams. When they grow to the extreme, their weight increases by about 2,000 to 3,000 times that of ant silkworms.

Tussah cocoons can be used to reel silk, which is the raw material for tussah silk. Tussah pupae are edible and, together with moths, are raw materials for the chemical, pharmaceutical and food industries. The eggs are good intermediate hosts for trichogrammatid wasps used for biological control.

3. What varieties of Guangtong silkworm seeds are there?

There are: mulberry silkworm, tussah silkworm, castor silkworm, cassava silkworm, horse silkworm, silkworm, amber silkworm, camphor silkworm, chestnut silkworm, catalpa silkworm, Chinese tallow silkworm, willow silkworm. Silkworm is a Lepidoptera insect, the main raw material source of silk, and occupies an important position in human economic life and cultural history.

1. Silkworm: Silkworm is also called domestic silkworm. Mulberry leaves are the most suitable natural food for silkworms. In addition to mulberry leaves, silkworms can also eat lettuce leaves, paper mulberry leaves, and lettuce leaves. Silkworms are one of the economic insects that spin silk and make cocoons.

2. Tussah silkworm: Tussah silkworm likes to eat plants of the Fagaceae family, such as oak oak and Mongolian oak, but it can also eat leaves of trees such as Artemisia selengensis, mountain yew, and apple.

3. Castor silkworm: Huili silkworm is the transliteration of castor silkworm. Castor silkworm leaves are the favorite food of castor silkworms, and castor silkworm cocoons can be used as raw materials for silk spinning;

4. Cassava silkworm: The living habits and characteristics of cassava silkworms are the same as those of castor silkworms, but they are generally fed with cassava;

5. Cordyceps silkworm: The living habits and characteristics of Cordyceps silkworm are the same as those of Castor silkworm, but they are generally fed with Cordyceps leaves;

6. Silkworm: Silkworms like to eat oaks, oaks, Mongolian oaks and other plants of the Fagaceae family. Silkworm cocoons can be woven into high-quality silk fabrics of different colors.

7. Amber silkworm: Amber silkworm is also called Assam or Muga silkworm. It is usually fed with nanmu leaves. Its cocoon is golden yellow, with good silk quality and amber luster. It is usually used to make precious clothing.

8. Camphor silkworm: Camphor silkworm is also called maple silkworm or fishing silkworm, and is generally fed with camphor leaves;

9. Chestnut silkworm: Chestnut silkworms are usually fed with walnut leaves or chestnut leaves;

10. Catalpa silkworm: Catalpa silkworms like to eat catalpa leaves. In addition, they also eat holly, paulownia, and camphor leaves.

11. Tung silkworm: Tung silkworm is also called big mountain silkworm or big tung silkworm, and the silk woven from the cocoons of Tung silkworm is known as "water silk".

12. Willow silkworm: Willow silkworm is also called large blue moth silkworm or middle tung silkworm. It is generally fed with leaves of maple, poplar, paulownia and other trees.

4. Can we raise silkworms when we plant Artemisia selengensis in the same year?

cannot.

It is absolutely not possible to raise silkworms on Artemisia selengensis, because Artemisia selengensis grows in the wild, and the climate and environment are not up to standard. If it rains, the silkworms will die. The environment is polluted or the silkworms eat leaves with pesticides, they will also die.

Since silkworms have very strict requirements on the environment, they are now basically raised in a greenhouse or in a disinfected room. Because silkworms are very delicate insects, from the time they are raised to the time they form cocoons, which is more than 20 days, you must ensure that the mulberry leaves they eat are free of pesticides and must be dry and free of water. In addition, silkworms eat more mulberry leaves in the last week of their cocooning, so you must ensure that there is enough mulberry leaves.

5. What do silkworms eat?

What silkworms eat

1. Silkworms are divided into natural silkworms, tussah silkworms, amber silkworms and mulberry silkworms. Different species eat different things.

2. Silkworms like to eat mulberry leaves, lettuce leaves, elm leaves, dandelions, etc.

3. Tussah silkworms like to eat mulberry leaves, oak and Mongolian oak leaves as food.

4. The silkworm feeds on the leaves of the Liaodong oak, Mongolian oak, cork oak, and sharp oak.

5. Amber silkworms mainly feed on nanmu trees, but also eat evergreen leaves such as tiger thorns of the Rubiaceae family.

Additional information:

Silkworm (scientific name: Bombyx mori) is an insect of the order Lepidoptera. It is the main source of silk and plays an important role in human economic life and cultural history. It is native to China and is commonly known as silkworm or nymph in southern China and Taiwan.

The silkworm is called "silkworm" in English because it uses silk to make cocoons. A cocoon is made from a strand of silk that is 300-900 meters long. Today, my country's silk production and exports account for more than 70% of the world's total, and it has become a major silk country that can dominate the world's silk price trend.
