The key to successfully raising summer silkworms lies in a combination of careful management and precise techniques. The core approach is centered around providing high-quality, well-satiated food, while implementing flexible strategies such as "three preventions and one diligence," "three early and one late," and "four uniform and two timely." These methods ensure optimal growth and minimize disease risks.
**Three Preventions and One Diligence**
1. **Disease Prevention**: Prior to starting the rearing process, thorough disinfection is essential. Five to seven days before the silkworms arrive, the entire silkworm room, tools, and surrounding area should be cleaned and scrubbed. A 1% chlorine-containing bleaching powder solution is sprayed twice, with each application left for at least 30 minutes. Silkworms and related equipment should be soaked for sterilization. After receiving the young silkworms (ants), frequent washing and regular disinfection are crucial. At the second instar stage, a daily spray of 1% soda water can help detoxify any pesticide exposure. To prevent fly infestation, flies must be added on time from the third instar.
2. **Heat Protection**: Keep the silkworm room cool and well-ventilated. Avoid direct drafts near the silkworms, especially during hot weather.
3. **Hunger Control**: Feed small silkworms with slightly larger leaves, and by the third instar, provide whole leaves. Feed them six times a day, ensuring they eat when they are most active, especially at night.
4. **Diligence in Cleaning**: Regularly remove sand and debris. Sand removal should only occur after the second instar to avoid stress on younger silkworms.
**Three Early and One Late**
- **Early Ant Acceptance**: Receive silkworm ants between 8 and 9 am, feeding them immediately with fresh mulberry leaves in small quantities.
- **Early Feeding Expansion**: Expand feeding areas early to allow even distribution.
- **Early Release of Thin Silkworms**: Ensure thin silkworms are released promptly to prevent overcrowding.
- **Late Mulberry Leaf Feeding**: Feed leaves just before the silkworms fall asleep, ensuring they eat and rest in a balanced cycle.
**Four Uniform and Two Timely**
- **Uniform Temperature**: Maintain stable temperatures—26–28°C for the silkworm chamber and 23–24°C for the silkworms themselves, not exceeding 30°C or 27°C respectively.
- **Uniform Distribution**: Ensure even spacing and appropriate size of silkworms. Summer silkworms are generally thinner than spring ones.
- **Uniform Feeding**: Provide the right amount of mulberry leaves so that silkworms can eat fully without waste.
- **Uniform Leaf Quality**: Use fresh, appropriately matured mulberry leaves. For the first four instars, use summer-harvested leaves; for the fifth instar, combine with new sprouts to avoid old or damaged leaves.
- **Timely Sleep Treatment**: Adjust sleeping schedules earlier than in spring, manage uneven development, and shorten the time between feedings to ensure smooth sleep cycles.
- **Timely Captain Selection**: When silkworms are nearing maturity, select and dilute them in batches. Three days before the final molt, open windows to maintain humidity but avoid strong winds.
By following these detailed practices, farmers can significantly improve the health and productivity of their summer silkworms, leading to better silk yields and quality.
