The work presented here is the experimental study of a synergistic ultrasonic and infrared treatment of mulberry silkworm pupae. The study investigated pupal mortalities as a function of processing time, temperature and ultrasonic frequency. The range of experimental conditions consisted of processing temperatures from 60–80°C, ultrasonic frequencies from 20–40 kHz, and processing times of 180–480 seconds. The results indicated that mortality rate was always found to be positively associated, with increase in processing time as well as ultrasonic frequencies. It was discovered that high efficiency could be achieved, especially at 40 kHz ultrasonic frequency and significantly lower temperature. According to the experimental results, recommended optimal regime parameters are you to help stifling with a high quality and to minimize its adverse effects on cocoon quality. The findings will be of practical importance in the development of advanced and energy-saving technological solutions for various sectors of sericulture. 5.3 × 10⁻⁵ to 1.42 × 10⁻⁴, approaching or exceeding acceptable limits. The findings demonstrate significant contamination of the Aluu River by microplastics with sediment acting as a major sink for these pollutants. The dominance of high-risk polymers, coupled with elevated health risk indices, indicates potential long-term ecological degradation and serious public health concerns for populations dependent on the river. Continuous environmental monitoring, strict regulation of industrial discharges, improved waste management practices, and public awareness initiatives are strongly recommended.
