Silkworm is an insect of high economic value, and its larvae can be made into silk. Here are some things to know about silkworms:
1. Silkworms are the larvae of Bombyx mori (the scientific name is Bombyx moth). The Bombyx moth is a lepidopteran insect that is the main source of silk.
2. The life span of silkworms is very short, only about two weeks. During this time, they complete processes such as growth, molting, and cocooning.
3. The food of silkworms is mulberry leaves, so they are also called "mulberry silkworms".
4. Silkworms have strong vitality and adaptability and can survive and reproduce in different environments.
5. The normal development of silkworms requires appropriate temperature and humidity. Generally speaking, the most suitable temperature is 25-30 degrees Celsius and the humidity is 70%-80%.
6. The silk in the cocoon is secreted by the saliva of the silkworm. The silkworm starts spinning silk on the third day and wraps up into a cocoon after finishing spinning on the fifth day.
7. Because silk fiber is very slender, it has high strength and durability and is widely used in various textile manufacturing.
8. Silkworm breeding is a very important agricultural industry, especially in China and other Asian countries, and has a history of thousands of years.
