CATDOLL : CATDOLL: When does the silkworm season start? (When does the silkworm season start?)

1. When to raise silkworms?

The silkworm breeding period is generally from April to November, that is, from the time when mulberry leaves sprout and open to the time when mulberry leaves turn yellow and fall off. It takes about 40-50 days for silkworms to transform from eggs into moths, which is related to factors such as temperature, humidity, and feeding in the growing environment.

2. What is the season for raising silkworms?

1. Silkworms are usually raised in spring and summer, which is roughly the same as the growth cycle of mulberry trees, to ensure sufficient supply of mulberry leaves. Prepare food: Mulberry leaves must be washed with clean water and dried before feeding. Do not feed silkworms with yellow and rotten leaves, otherwise the silkworms will be poisoned or have diarrhea. In order to prevent the excess leaves from wilting quickly, put them in a plastic bag, tie the bag tightly, and place it in a cool place.

2. Feed the silkworms with leaves 4 times a day, early in the morning, at noon, in the afternoon, and at night. The amount should be appropriate each time to avoid waste. You can put more leaves at night because the silkworms eat mulberry leaves all night. Ant silkworms should be fed with young leaves, and the leaves are best cut into pieces or strips.

3. Clean up the feces and leftover leaves frequently: When changing leaves for the silkworms, you can directly cover the old leaves with new leaves, and remove the old leaves after the silkworms have crawled onto the new leaves. This can reduce the casualties of the silkworms and facilitate the removal of leftover leaves and silkworm feces.

4. Do not spray pesticides in the silkworm room as this will harm the silkworms.

3. Which season is suitable for raising silkworms?

Spring or Summer

Answer 1. Silkworm rearing time: Generally, silkworm rearing takes place in spring and summer (starting around April). Silkworms mainly feed on mulberry leaves, so silkworm rearing needs to be basically consistent with the growth cycle of mulberry trees, so that there are enough mulberry leaves for silkworms to eat. 2. Silkworm rearing frequency: In Jiangsu and Zhejiang silkworm regions, silkworm rearing can be carried out theoretically from April to November each year, but generally only 3-5 times.

4. Which month is it best to raise silkworms?

March-June.

The most suitable time for raising silkworms is generally March in spring and May and June in summer.

March is the time when mulberry leaves sprout and grow leaves. Spring silkworms at this time have tender mulberry leaves to eat. With sufficient mulberry leaves to feed on, the silkworms grow bigger and fatter.

5. What is the best season for raising silkworms?

Silkworms are usually raised in spring, around the Qingming Festival, when the temperature is relatively warm. If they are raised too early, the temperature will be too low and they will be frozen. In addition, the leaves of the mulberry tree have not grown much yet and cannot meet the needs of the silkworms.

6. What is the best season for raising silkworms?

Silkworm breeding time: Usually, silkworm breeding takes place in spring and summer (starting around April each year). Because silkworms mainly feed on mulberry leaves, the breeding of silkworms needs to be closely related to the growth cycle of mulberry trees.

7. Which month do we start raising silkworms?

Around April.

Generally speaking, silkworm breeding starts around April each year, specifically in spring and summer. Since the main food source for silkworms is mulberry leaves, the breeding of silkworms needs to be basically consistent with the growth cycle of mulberry trees, so as to ensure that there are enough fresh mulberry leaves for the silkworms to eat.

In the sericulture areas of Jiangsu and Zhejiang, silkworms can theoretically be raised during the eight months from April to November each year, but generally only 3-5 times.

8. Which month is it best to raise silkworms?

1. Generally speaking, the season for raising silkworms is spring and summer every year (starting around April each year). Since the main food source for silkworms is mulberry leaves, the season for raising silkworms and the growth cycle of mulberry trees need to be roughly the same to ensure that there are enough mulberry leaves to feed the silkworms.

2. The season of sericulture is related to the region. In the sericulture areas of Jiangsu and Zhejiang, theoretically, sericulture can be carried out during the eight months from April when mulberry trees sprout and open leaves to November when mulberry leaves turn yellow and fall off, but generally only 3-5 times a year. The sericulture areas in the Pearl River Basin raise sericulture more frequently than those in Jiangsu and Zhejiang, while some sericulture areas around the Yellow River or in the north raise sericulture less frequently than those in Jiangsu and Zhejiang.

9. When does one start raising spring silkworms?

1. Time for raising silkworms

Generally speaking, silkworm breeding starts around April each year, specifically in spring and summer. Since the main food source for silkworms is mulberry leaves, the breeding of silkworms needs to be basically consistent with the growth cycle of mulberry trees, so as to ensure that there are enough fresh mulberry leaves for the silkworms to eat.

2. Number of times of raising silkworms

The number of times silkworms are raised each year is related to the region. In the Jiangsu and Zhejiang silkworm areas, silkworms can be raised theoretically in the eight months from April (when mulberry trees sprout and open leaves) to November (when mulberry leaves turn yellow and fall off), but generally only 3-5 times a year. The silkworm areas in the Pearl River Basin raise silkworms more often than those in Jiangsu and Zhejiang, while the silkworm areas around the Yellow River and the northern regions raise silkworms less often than those in Jiangsu and Zhejiang.

2. What factors should be paid attention to in silkworm breeding?

1. Temperature

The suitable temperature for first-instar silkworms is 27-28℃, the suitable temperature for second-instar silkworms is 26-27℃, the suitable temperature for third-instar silkworms is 25-26℃, the suitable temperature for fourth-instar silkworms is 24-25℃, and the suitable temperature for fifth-instar silkworms is 23-24℃.

2. Humidity

The suitable humidity for first-instar silkworms is 80-85%, the suitable humidity for second-instar silkworms is 85-90%, the suitable humidity for third-instar silkworms is 75-80%, the suitable humidity for fourth-instar silkworms is 70-75%, and the suitable humidity for fifth-instar silkworms is 65-70%.

3. Mulberry leaf selection

(1) One-year-old silkworms: Use the third leaf from the top bud on the mulberry tree, which should be yellow with green in color.

(2) Second-instar silkworms: Use the fourth leaf from the top bud on the mulberry tree, which should be green with yellow in color.

(3) Third-instar silkworms: Use the 5th to 6th leaves from the top bud on the mulberry tree. The leaves should be light green and shiny.

(4) For fourth- and fifth-instar silkworms: Use the 7th to 15th leaves from the top bud, and the leaves must be fresh.

(5) There should be no water on the mulberry leaves.

4. Other matters needing attention

(1) When the temperature is high, you need to open doors and windows for ventilation.

(2) When raising silkworms, avoid direct sunlight.

(3) Mosquito-repellent coils should not be used in silkworm breeding areas because they are poisonous to silkworms and bees.

10. When is the season for raising silkworms?

Silkworms are usually raised in spring and summer. The most important thing to note about silkworm raising is that the growth cycle should be the same as that of mulberry trees to ensure that the silkworms have enough mulberry leaves to eat. Silkworms are metamorphosed insects, and the most common ones are mulberry silkworms, also known as domestic silkworms.
