the article presents the developed device for mortification a silkworm pupa inside a cocoon by exposing it to infrared radiation and the technology for its use. The schemes of temperature changes in the structural bonds of a live cocoon pupa during its mortification under the influence of infrared radiation on cocoons obtained in different seasons of the year and the corresponding results of practical research are presented and analyzed. Studies have shown that the distance between the cocoon and the infrared lamp affects the temperature of the structural connections of the pupa and the cocoon. It was found that the treatment of cocoons with infrared radiation for a short period of time can cause an increase in the temperature of the pupa to an average of 79oC, and the temperature of the cocoon shell in comparison with the pupa decreases to 27oC. It was also found that when processing with distances between cocoons and infrared lamps equal to 10cm, 15cm and 20cm-the temperature of the pupa and the cocoon shell obtained in different seasons of the year may differ and the temperature difference of the pupa reaches 4oC, and the temperature difference of the cocoon shell is up to 9oC. In this regard, the process of mortification the pupa cocoons, obtained in spring, can be performed in a short time, resulting in saved technological parameters of the shell cocoons at a high level, which leads to improving the efficiency of unwinding cocoons enterprises, as well as to acquire high quality raw silk.
