Mosquito flight tone was amplified and digitally sampled at 20,000 samples per second (Hz). Resampling of the resulting sound files at 1,000, 5,000, and 10,000 Hz allowed comparison of flight tone frequency distributions for males and females of Aedes aegypti (L.) and A. albopictus (Skuse). Frequency distributions for females of the two species did not overlap at sampling rates of 5,000 Hz or higher, whereas considerable overlap was observed at the 1,000 Hz sampling rate. Males of the two species produced flight tones higher in frequency than those of females, but similar to each other. At the highest sampling rate, seven flight tone harmonics were measured for each species. Close correspondence of the means of the flight tone harmonics (corrected for harmonic number) demonstrated that any of the harmonics may be used accurately and precisely to calculate flight tone frequency. These data indicate that flight tone differences have been selected in these species and could act as an isolating mechanism for mating.
蚊子飞行音调被放大，并以每秒20000次采样（赫兹）进行数字采样。将所得声音文件重新采样至1000赫兹、5000赫兹和10000赫兹，以便比较埃及伊蚊（L.）和白纹伊蚊（Skuse）雌雄个体的飞行音调频率分布。在5000赫兹或更高的采样率下，这两个物种雌性的频率分布没有重叠，而在1000赫兹采样率下观察到相当大的重叠。这两个物种的雄性产生的飞行音调频率高于雌性，但彼此相似。在最高采样率下，对每个物种测量了七个飞行音调谐波。飞行音调谐波平均值（针对谐波数量进行校正）的密切对应表明，任何一个谐波都可被准确精确地用于计算飞行音调频率。这些数据表明，这些物种的飞行音调差异已被选择出来，并可能作为交配的隔离机制。
