CATDOLL : CATDOLL: What is the most suitable temperature for silkworm rearing? (What is the most suitable temperature for silkworm rearing?)

1. What are the growth environment requirements for silkworms?

Temperature: The temperature range for silkworm growth and development is 20-30℃. The suitable temperature for feeding and rearing is usually 27-28℃ for the first instar, 26-27℃ for the second instar, 25-26℃ for the third instar, 24-25℃ for the fourth instar, and 23-24℃ for the fifth instar. It should be kept at 24.5-25℃ in the early stage of cocooning and 24℃ in the late stage of cocooning. Humidity: The relative humidity is 95% in the first instar, and it decreases by 5-6% with each subsequent instar.

2. What is the appropriate temperature for raising silkworms?

Temperature, silkworms are cold-blooded animals.

Changes with the external temperature.

The temperature range for growth is 20 to 30 degrees Celsius.

The higher the temperature within the suitable temperature range, the better the growth and development.

Fast, above 30 degrees Celsius and below 20 degrees Celsius

Under this condition, the silkworms develop slowly, which is not conducive to the

Growth, long contact time will affect the health of silkworms.

The optimum temperature for raising young silkworms at 1 to 2 years old is 27 to 28 degrees.

The best temperature for aging is 26 degrees Celsius.

The optimum temperature for raising silkworms is 24 to 25 degrees Celsius.

The temperature for raising young and adult silkworms should not exceed 30

The young silkworms are kept in a high temperature environment of 27 to 28 degrees Celsius.

Feeding under the water, eating more mulberry, digestion and absorption are accelerated,

The silkworms gain weight and are healthy.

Celsius low temperature feeding mulberry long time, accumulation of breeding

The silk glands are full and enlarged, with more silk material and cocoons.

Layer thickness.

3. How many silkworms should be raised?

The most suitable temperature for silkworm rearing is between 20-30℃. The higher the temperature within the suitable temperature range, the faster the growth rate. Temperatures above 30℃ or below 20℃ will directly affect the growth of silkworms. Silkworms are temperature-changing animals, and their body temperature will change with the external temperature.

4. What is the most suitable temperature for raising silkworms? c?

The temperature of silkworm is 7-40℃, and the optimum temperature for feeding is 20-25℃. The temperature of tussah is 8-30℃, the optimum temperature for development is 11-25℃, and the most suitable temperature is 22-24℃.

5. What is the suitable temperature for silkworms?

The temperature for silkworm development is 7-40℃, and the optimum temperature for feeding is 20-30℃. Silkworms are metamorphosis insects, and the most common one is the mulberry silkworm, also known as the silkworm, which is one of the economic insects that spins silk and spins cocoons and feeds on mulberry leaves.

Silkworms feed on mulberry leaves, and their bodies turn white after eating them continuously. After a period of time, they begin to shed their skins. The molting period lasts for about a day, and they do not eat or move like they are sleeping. This is called "hibernation."

After molting once, it is the second-instar larvae. It grows one year older each time it molts. The larvae molt four times in total and become fifth-instar larvae. They then eat mulberry leaves for 8 days to become mature silkworms and start spinning silk cocoons. Extended information: Some characteristics of silkworm eggs, larvae (silkworm babies), silkworm pupae, and silkworm moths can be used to identify the sex of the silkworm. However, the most widely used method is to identify the sex of old silkworms, silkworm pupae, and silkworm moths.

The most reliable feature for identifying the sex of silkworms is the eighth and ninth abdominal segments. Female silkworms have four transparent spots on the eighth and ninth abdominal segments, while male silkworms have a transparent spot in the middle of the ninth abdominal segment. However, generally speaking, it is most difficult to distinguish the sex of silkworms during the larval stage. Except for senior technicians, ordinary silkworm farmers often find it difficult to distinguish.

The characteristics of male and female pupae are also identified by utilizing the structure of the eighth and ninth abdominal segments.

In the center of the ventral surface of the eighth and ninth segments of the female pupa's abdomen, there is a straight line that separates the eighth and ninth segments; while in the center of the ventral surface of the ninth segment of the male pupa's abdomen, there is a pair of small protrusions.

6. What is the maximum suitable temperature for raising silkworms?

The growth temperature is more suitable between 20 and 30 degrees. Above 30 degrees or below 20 degrees will affect the growth.

7. What is the most suitable temperature for raising silkworms?

① Temperature. Silkworms are cold-blooded animals. Their body temperature changes with the change of external temperature. The temperature range for normal growth and development of silkworms is 20-30 degrees Celsius. The higher the temperature within the suitable temperature range, the faster the growth and development. When the temperature exceeds 30 degrees Celsius and is below 20 degrees Celsius, the development speed of silkworms is slow, which is not conducive to the growth of silkworms. Long contact time will affect the health of silkworms. The suitable temperature for raising young silkworms from 1 to 2 years old is 27-28 degrees Celsius, and 26 degrees Celsius is suitable for the third age. The Silk Quilt Network recommends that the suitable temperature for raising adult silkworms is 24-25 degrees Celsius. It is better to raise young and adult silkworms at a temperature not exceeding 30 degrees. Young silkworms are raised under high temperature conditions of 27-28 degrees Celsius, eat more mulberry, digest and absorb faster, gain weight, and are healthy. Adult silkworms are raised under low temperature conditions of 24-25 degrees Celsius, eat mulberry for a long time, accumulate more nutrients, have full and hypertrophic silk glands, have more silk substances, and have thick cocoon layers. ② Humidity. The humidity in the environment can affect the growth, development, mulberry food intake, digestion and absorption, molting, and silkworm hygiene. In a humid environment, silkworms breathe vigorously, eat more mulberry, digest and absorb faster, grow and develop faster, and have a short lifespan. However, high humidity can cause pathogenic microorganisms to reproduce quickly, and silkworms are susceptible to infection and disease. A dry environment is beneficial to the hygiene of the silkworm's body, but the mulberry leaves are easy to wither and affect their mulberry intake, causing hungry silkworms, thin silkworms, and difficulty in molting. Therefore, it is better to keep the air moist and the silkworm's body dry. The suitable humidity range is that the relative humidity of the young silkworms is 90% in the first age, and then decreases by 5% for each age, and the fifth age for adult silkworms.

8. What environmental temperature and light do silkworms prefer?

Silkworms are suitable for growing in an environment with a temperature range of 22-29 degrees Celsius, and their most suitable growth temperature is around 27 degrees Celsius. A silkworm eats about 25 grams of mulberry leaves in its lifetime. If you feed 40 silkworms, you only need 1 kilogram of mulberry leaves. But in the actual feeding process, some mulberry leaves will be wasted, so more mulberry leaves will be needed.
