Female courtship signal of the brown planthopper was made of many continuous regular pulses and male ' s signal was made of similar syllabics and had two types with different time domain characteristics. second male vibrational signal differed from male courtship signal with wide spectrum range and regular syllabics frequency. time domain characteristics of signals in different individuals even the same individual were different
頻域特徵分析知，褐飛虱雌蟲求偶嗚聲信號的頻域特性較穩定，個體內比個體間差異小；雄蟲求偶嗚聲信號s 、 e片段頻譜范圍較寬，但主振頻率比較接近，差異不顯著； m片段頻帶較窄，主振頻率mvf略小於s 、 e片段，變異較小； m片段脈沖重復頻率prf為幻 -
Synthesized signals with different pulse repetition frequencies ( prf ) and main vibration frequencies ( mvf ) were presented to the brown planthopper. the results showed that prf was a sensitive and important signal characteristic in mating choice. the prf and mvf sensitive ranges of male signals were 70 ~ 90hz, 200 ~ 1700hz separately, and of female signals were about 22hz, 100 ~ 300hz separately
雄蟲敏感的prf范圍在22hz左右，雌蟲敏感的paf范圍為70 90hz ，這與實際的雌、雄蟲求偶鳴聲的pm變化范圍是一致的；雌、雄蟲能對mvf變化范圍較大的信號敏感，雄蟲敏感的mvf范圍為100 300hz ，與雌蟲求偶嗚聲的mvf變化范圍是一致的，而雌蟲敏感的mvf范圍為200 1700hz ，要比實際的雄蟲求偶鳴聲的mvf變化范圍大的多。
