The optimum temperature for silkworm rearing is 23~25°C. The 4th instar should not be lower than 24°C. If the 5th instar temperature is higher than 28°C, the food intake is reduced, the age is shortened, the stress resistance is reduced, the calving volume is low, and the cocoon quality is reduced.
The suitable humidity for silkworm rearing is 65%~70%. When the humidity is too low, mulberry leaves are easily withered and affect the eating rate. Humidity is too high, silkworm body water is not easy to evaporate, body temperature rises, germs easily breed, is not conducive to large silkworm rearing.
Large silkworms are light-resistant and tend to concentrate in dark places. In addition to keeping the indoor light evenly, give Mulberry a uniform seat.
The large silkworm room should always maintain an airflow of 0.1-0.3 m/s in order to discharge the bad gas in the silkworm room in time and keep the indoor air fresh. Therefore, the large silkworm room should be provided with front and rear convection (door) windows. The size of the window is not less than 120 cm and 80 cm.
