CATDOLL : CATDOLL: When is the best time to raise silkworms? (When is the best time to raise silkworms?)

1. When is the best time to raise silkworms?

Generally speaking, it is more suitable to raise silkworms in spring and summer, which is roughly between April and July. The best time to raise silkworms is roughly the same as the growth cycle of mulberry trees, because only at this time can an adequate supply of mulberry leaves be guaranteed and the silkworms can grow healthily.

The advantages of raising silkworms in spring are that the weather is mild and the quality of mulberry leaves is better, so the silkworms are of higher quality and yield. The time for raising spring silkworms cannot be too late, and it can be done around April. Otherwise, if the weather is bad later, the number of silkworms will be greatly reduced.

3. 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.

4. When is the best season to pick mulberry leaves and raise silkworms?

Mulberry picking and silkworm rearing are usually done in spring and summer. The growth cycle of silkworm rearing should be roughly the same as that of mulberry trees to ensure an adequate supply of mulberry leaves. Silkworms are metamorphosed insects, and the most common one is the mulberry silkworm, also known as the domestic silkworm, which is one of the economic insects that feeds on mulberry leaves and spins silk cocoons. The silk it spins can be used to make silk quilts or woven into silk fabrics, which have very high economic value.

5. Which month is it best to raise silkworms?

Raising silkworms on mulberry leaves is a good time to do so in June. In June, mulberry leaves are lush, nutritious and easy to feed, so there is enough food for the silkworms. The temperature is also suitable, the silkworms grow fast and the production cycle is short, so it is a good time to raise silkworms.

6. Which month is suitable for raising silkworms?

The best time to raise silkworms is June. In the north, the weather starts to get warmer in June, so it is more suitable to raise silkworms at this time. Of course, in Hainan, you can raise silkworms around March.

7. 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.

8. What is the best time to breed silkworms?

It is best to start growing the mulberry trees after May 1st, because the leaves are already very large at that time and picking them will not affect the growth of the trees. However, you should still grow less at first and gradually grow more.

1. Living habits: Silkworms are metamorphosis insects, the most common of which is the mulberry silkworm, also known as the domestic silkworm, one of the economic insects that feeds on mulberry leaves and spins silk and makes cocoons. The mulberry silkworm originated in China, and its development temperature is 7-40℃, and the suitable temperature for breeding is 20-30℃. Silkworms feed on mulberry leaves, and their bodies turn white after eating mulberry leaves continuously. After a period of time, they begin to shed their skins. The molting lasts for about a day, and they do not eat or move like sleeping. This is called "hibernation". After molting once, it is a second-instar larva. It grows one year older every time it molts. The larvae molt four times in total, becoming fifth-instar larvae, and then eat mulberry leaves for 8 days to become mature silkworms, and begin to spin silk and make cocoons.

2. Distinguish between male and female:

Some characteristics of silkworm eggs, larvae (silkworm babies), pupae, and moths can be used to identify the sex of silkworms. However, the most widely used method is to identify the sex of old silkworms, pupae, and moths.

The most reliable feature for identifying the sex of silkworms is the eighth and ninth abdominal segments: there are four transparent spots on the ventral surface of the eighth and ninth segments of female silkworms; there is a transparent spot in the center of the ventral surface of the ninth segment of male silkworms.

The characteristics of male and female pupae are also used to identify the structure of the eighth and ninth abdominal segments. In the middle of the ventral surface of the eighth and ninth abdominal segments of the female pupa, there is a straight line that separates the eighth and ninth abdominal segments; while in the middle of the ventral surface of the ninth abdominal segment of the male pupa, there is a pair of small protrusions and an x-shaped symbol.

As for distinguishing male and female moths, in addition to identifying features such as antennae and abdomen size, the most reliable way to identify male and female moths is by their external genitalia. For example, the female moth has a black bone plate near its mating hole, and the male moth has a pair of claspers.
