鼠类超声通讯在鼠害防治中的应用

Application of ultrasonic communication in rodent management and control

鼠类针对不同刺激或不同目的可发出超声波,且超声信号的频率和时程随年龄、性别、种类、自然和社会环境的不同而出现差异性变化,同时可接收超声波信号。该文介绍了鼠类超声信号的研究成果,并阐述当前超声波驱鼠器的使用状况及存在问题,为新型高效超声驱鼠产品的研发和使用提供建议,从而更好地开展鼠害防治工作。

Rodents emit and perceive calls in the ultrasonic range, i.e., above the human hearing threshold of about 20 kHz： so-called ultrasonic vocalizations （USV）. They emit USV, which differ in frequencies and durations according to their age, sex, species, and the physical and social behaviors, in response to different stimuli and for different purposes. This paper describes the characteristics and functions of the USV in rodents, and also elaborates current status of ultrasonic rodent repellent devices. It is very important for the research and development of the new, efficient ultrasonic rodent deterrent devices.
