The Colorado potato beetle (Leptinotarsa decemlineata) is one of the most destructive pests of potato crops and has developed resistance to numerous insecticides. This study aimed to develop and evaluate a portable ultrasonic device powered by solar energy and a rechargeable battery to suppress beetle activity in potato fields. The device emitted ultrasonic waves in the 20-40 kHz frequency range, targeting the beetles’ sensitivity to sound vibrations. Field trials showed that continuous ultrasonic exposure reduced mating activity by 65-70%, nearly halted reproduction within 14 days, and decreased leaf damage by 35%. As a result, potato yield increased by approximately 32,5% compared to untreated plots. These findings indicate that ultrasonic technology can serve as an eco-friendly and sustainable method of pest management in potato cultivation.
