Abstract
In silkworm rearing in Uzbekistan, one of the main problems is the maintenance of a hygrothermal regime. Scientific research has been carried out to create optimal air temperature and relative humidity for rearing hybrid silkworms from the 1st instar to the 5th instar. In the experiments, the silkworms were fed in two different experiments and in the same comparative method. In silkworm rearing, the use of fabric and polyethylene film to retain humidity in a special device has been found to save mulberry leaf consumption by 15,3-18,7%, and to shorten the worm cycle by 2,7-4,0 days and due to maintaining the hygrothermal regime, a significant increase in silkworm growth and weight was observed. KEYWORDS: silkworm, mulberry leaves, temperature, humidity, cocoon, silk.
