During the summer silkworm season, which is a critical time for pest control, it's essential to prevent pesticide poisoning. Agricultural chemicals must be strictly kept away from mulberry fields and silkworms to avoid contamination of mulberry leaves. When spraying crops near the silkworm house, windows and doors should be closed promptly to minimize exposure. It's recommended to use organic nitrogen-based pesticides that are free from insecticides when treating silkworms. Failure to do so can result in severe poisoning, which could harm or even kill the silkworms.
Farmers should always wash their hands and change into clean clothes before feeding the silkworms. Mulberry leaves should be sprayed with foliar fertilizer or moistened before feeding. The use of any equipment previously used for pesticides is strictly prohibited. Before feeding large quantities of mulberry leaves, it's important to conduct a small-scale trial to ensure they are safe and non-toxic.
Commonly used pest control materials during summer and autumn contain pyrethrin and other harmful substances that may lead to chronic poisoning in silkworms. Products like Radar, Mop, and other mosquito repellents are highly toxic to silkworms and should never be used in the silkworm room. If these products are used near the silkworm house, the area must be completely sealed off.
To manage flies, which are more prevalent in summer and autumn, it's important to install screen doors and windows around the silkworm area. If necessary, fly-killing sprays can be used, but only in a safe and controlled manner to avoid harming the silkworms.
For rodent control, it's crucial to plug all rat holes before the silkworm rearing period begins. Keep the silkworm frames at a distance from walls and spread lime powder or silkworm medicine around the base of the frames to prevent rats from climbing up. Regular pest control measures should be implemented, and keeping cats in the area can help reduce rodent damage significantly.
In summer, high temperatures can affect silkworm health. To keep the silkworm room cool, spray well water early in the day and hang damp cloths or wet grass curtains. Keep doors and windows closed during the day to block hot air. At night, open the windows fully to allow fresh air in and mist the mulberry leaves with clean water. Using electric fans inside the room to circulate air is also an effective way to combat heat stress.
