Abstract: Objective To know the effect of ultrasonic on the behavior of mice in lab,and the field repelling effect of ultrasonic rodent repeller on Rattus norvegicus,one of the dominant commensal rodent in China,so as to exploit the applying technique of ultrasonic on rodents control.Methods The activity of tested rodent was represented by percent of rodent footmarks in power.Rodent sticky trap and ultrasonic rodent repeller were used together in R.norvegicus test.Results Both before and after ultrasonic repeller was used for two days in lab,the percent of rodent footmark in power per Kunming white mouse one day was 0.3%-1.4%,the footmarks were mainly at the edge of room;while for 3 to 12 days repeller was used,the percent of rodent footmarks were up to 12.5% and were mainly in the centre of the tested room,there was significant difference.If the ultrasonic repeller was used only in field R.norvegicus control,there was no significant difference of control effect between without ultrasonic repeller and with the repeller,with a positive power(36.0±11.4)% and(30.9±8.2)% respectively.When ultrasonic repeller and rodent sticky trap were applied at the same time,for two repetitions we obtained a same result that ultrasonic repeller had significant effect on R.norvegicus control.For the first repetition,there was no rat positive power after 8 days and for the second time no rat positive power was after 19 days but with one at the 42st day.Conclusion Mice activity behavior can be affected when the mice were exposed in ultrasonic;ultrasonic repeller might control rodent by repelling their breaking in;during R.norvegicu control rodent sticky trap and other methods should be used together with ultrasonic repeller for rodent prevention and control.
