| Tools | Key points for use | alternative |
|---|---|---|
| pointed scissors | 45 degree angle cut | scalpel |
| Elbow tweezers | Clamp the middle part of the pupa body | bamboo clip |
4.Take out the silkworm chrysalis: Gently clamp the brown pupa body with tweezers, slowly rotate and pull it out to avoid damaging the epidermis.
5.Follow-up processing: The removed silkworm chrysalis can be used immediately or stored in a refrigerator (can be stored at 0-4℃ for 3 days).
3. Solutions to common problems
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| Damaged pupa | Tools are not sharp enough | Replace professional tools |
| difficult to remove | Not enough soaking time | extended to 8 minutes |
| Death of pupa | Operating force is too large | Practice simulation operations |
4. Collection of innovative methods from netizens
1.Negative pressure suction method: Use the modified suction tube device to remove the complete pupa body through the air pressure difference (video demonstration by "Handmade Lao Li", the UP host of B station).
2.cryogenic freezing method: Freeze the cocoons for 10 minutes and then take them out. The pupae will shrink and be easier to separate (tested by Douyin user @ Silkworm Master to be effective).

2. Live pupae should be handled as soon as possible after being taken out to avoid prolonged exposure to the air.
3. Children need to be accompanied by an adult when operating. It is recommended to wear goggles to prevent cocoons from entering the eyes.
4. Silk from silkworm cocoons after pupae can still be used for textiles and must be properly preserved.
According to the latest popular science from agricultural expert @Sericulture Research Professor Zhang, scientific pupae removal can increase silk utilization by 15% while ensuring that the integrity of the pupa body reaches more than 90%. With the increase in the number of home sericulture enthusiasts, this traditional skill is being given a new era connotation.
