The present study aimed to investigate the lethal effects of ultrasonic sound frequencies, which are thought to cause resonance on Culex (Cx.) pipiens, Linneaus, 1758 larvae. Modern integrated pest management (IPM) programs combine biological, cultural, and/or chemical methods to control populations of this pest. Ultrasonic sound waves are used in many fields for pest control. This study was conducted with eight-hour-long experiments in which 720 larvae were placed in piezo-transducer immersed containers producing sound frequency at three different levels (20.0 kHz, 28.8 kHz, and 32.8 kHz). In statistical analyses, Two-Way ANOVA and Multiple Regression Analysis were used. The results revealed that, among all frequencies to which mosquito larvae were exposed, 28.80 kHz (above the ultrasonic limit) was found to be the most effective with mortality between 70 and 100%. I also determined that ultrasonic sound waves applied caused the highest mortality of 96.67% to 100% on Cx. pipiens 1st instar larvae. Also, between %6.67 and %10 larval death was detected in control groups. In statistical analyses, it was determined that the ultrasonic sound frequency values were applied to the Cx. pipiens larvae and the exposure time directly affected the mortality. Ultrasonic frequency, transmitted to the water in a container caused high rates of larval mortality with a resonance effect in the mosquito larvae close to the natural frequency. I believe that the ultrasonic frequency of 28.8 kHz is similar to the resonant frequency of Cx. pipiens larvae. The high sound frequencies (ultrasonic), close to the resonance limit, could effectively augment conventional larvicide applications with the greatest mortal effect in smaller areas.

本研究旨在调查超声波频率的致命影响，这些频率被认为会引起库蚊 (Cx.) pipiens共振，Linneaus，1758 年幼虫。现代综合害虫管理 (IPM) 计划结合了生物、文化和/或化学方法来控制这种害虫的种群。超声波可用于许多领域的害虫防治。这项研究进行了长达八小时的实验，其中 720 只幼虫被放置在压电传感器浸入式容器中，产生三个不同级别（20.0 kHz、28.8 kHz 和 32.8 kHz）的声音频率。在统计分析中，使用了双向方差分析和多元回归分析。结果表明，在蚊子幼虫暴露的所有频率中，发现 28.80 kHz（高于超声波限值）是最有效的，死亡率在 70% 到 100% 之间。我还确定施加的超声波导致的死亡率最高，为 96.67% 到 100%CX。pipiens 1 龄幼虫。此外，在对照组中检测到 %6.67 和 %10 之间的幼虫死亡。在统计分析中，确定将超声波频率值应用于Cx。pipiens幼虫和暴露时间直接影响死亡率。超声波频率传输到容器中的水中会导致幼虫死亡率高，蚊子幼虫的共振效应接近自然频率。我相信28.8 kHz的超声波频率与Cx的共振频率相似。pipiens幼虫。接近共振极限的高声频（超声波）可以有效地增加常规杀幼虫剂的应用，在较小的区域内具有最大的致死效果。
