The ideal temperature for high-temperature-resistant silkworms is between 24°C and 27°C. If the indoor temperature exceeds 30°C, immediate cooling measures should be taken to ensure optimal conditions for the silkworms. After feeding, it's important to close doors and windows to maintain a stable environment. A shade structure or pergola should be placed both before and after the silkworm rearing area. Water should be sprinkled on the floor, and mechanical ventilation should be used to help regulate temperature and humidity.
To prevent hunger and heat stress, silkworms grow quickly, so the amount of mulberry leaves provided and the frequency of feedings should be increased. During the 4th to 5th instar stages, silkworms can be fed 4 to 5 times daily to support their rapid development.
Before rearing silkworms in early autumn, thorough disinfection is essential. After disinfection, the silkworms should be exposed to air for 3 to 4 days to ensure all pathogens are eliminated. Regular use of fresh lime powder and disease-prevention agent No. 1 helps maintain hygiene and prevents common silkworm diseases.
During hot and dry seasons, mulberry horse infestations can damage mulberry leaves. To control this, an 80% Dichlorvos Emulsion diluted at 2000 times can be applied twice to effectively eliminate the pests and maintain leaf quality.
During the peak season of rice and cotton around August, pest control activities must be carefully managed. When spraying crops, attention should be paid to wind direction to avoid contaminating mulberry leaves. For fields located near mulberry plantations, it’s crucial to collect and test feed leaves before harvesting. Only undamaged, non-toxic mulberry leaves should be used. In case silkworms are poisoned, they should be rescued immediately by removing sand from their bodies and feeding them fresh, non-toxic mulberry leaves. Alternatively, mulberry leaves can be sprayed with 1% fresh lime water or 500-times diluted adrenaline to aid in detoxification.
