BACKGROUND
The German cockroach, (Insecta: Blattodea, Blattellidae), which occurs widely in human buildings, is a small cockroach species. Cockroach control chemical pesticides are toxic to the environment, and it is sometimes impossible to prevent them. Controlling through ultrasonic waves can be efficient and less dangerous for the environment.
METHODS
In this study, the repellency and lethal effect of ultrasonic waves on male and female German cockroaches was tested in a twin glass cubic chamber at laboratory condition. The wave frequencies tested ranged from 20 to 100kHz with 5kHz steps. A signal generator generated these frequencies, and the piezoelectric transmitter of these ultrasonic waves was positioned in the chamber's center on the upper side.
RESULTS
Fisher's test showed that there was the greatest repellency effect in both male and female at frequencies of 35 and 40kHz. According to the results of the regression test, the most lethal effect is at the frequencies of 40 and 75kHz.
CONCLUSION
The operating ultrasonic frequencies investigated in this study can be used to repel and kill German cockroaches as pests endangering human health and environment.
背景
德国小蠊（昆虫纲：蜚蠊目，姬蠊科）广泛分布于人类建筑中，是一种小型蟑螂物种。用于控制蟑螂的化学杀虫剂对环境有毒，且有时难以避免使用。通过超声波进行控制对环境可能更高效且危害更小。
方法
在本研究中，在实验室条件下的双玻璃立方箱中测试了超声波对雄性和雌性德国小蠊的驱避和致死效果。测试的波频率范围为20至100kHz，步长为5kHz。信号发生器产生这些频率，这些超声波的压电发射器位于箱内上方中心位置。
结果
费舍尔检验表明，在35kHz和40kHz频率下，雄性和雌性德国小蠊的驱避效果最佳。根据回归测试结果，致死效果最佳的频率为40kHz和75kHz。
结论
本研究中所研究的工作超声波频率可用于驱避和杀死作为危害人类健康和环境的害虫的德国小蠊。
