Intro to Silkworm Farming: Rearing Tips and Common Problems Explained

Sericulture refers to the traditional agricultural practice of raising silkworms (Bombyx mori) by hand to obtain silk, and it has a long history in our country. Silkworms feed mainly on mulberry leaves and go through four developmental stages in their lifetime: egg, larva, pupa and adult. The rearing cycle from hatching to cocoon spinning usually takes about one month, with the exact time affected by temperature and rearing conditions.

The key to raising silkworms lies in the quality of the mulberry leaves and environmental control. The leaves must be fresh and clean, and should not be wet or contaminated with pesticides, or silkworm diseases are easily triggered. The rearing room should be well ventilated, kept at a suitable temperature, protected against rats and flies, and the silkworm droppings should be cleaned up promptly to reduce the buildup of pathogens.

Silkworm varieties can be divided by voltinism into multivoltine, bivoltine and univoltine types, and cocoons also come in white and yellow. Different varieties differ somewhat in their ability to adapt to climate, so rearers can choose according to local conditions; beginners are advised to start with varieties that are more resistant and easier to raise.

Silk is a natural protein fiber that can be woven into silk fabric and is also used to make items such as silk quilts; silkworm pupae, droppings and moths likewise have value as feed and fertilizer. In addition, because it can fully demonstrate the metamorphosis of an insect, sericulture is often used in schools for nature observation education.

Beginners often encounter problems such as poor appetite and abnormal body color in silkworms, which are mostly related to contaminated mulberry leaves or improper environmental humidity. Sick silkworms should be isolated and dealt with promptly, rearing tools should be disinfected frequently, and keeping things clean is the most effective way to prevent silkworm diseases.
