| 10. | 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
雄虫敏感的prf范围在22hz左右，雌虫敏感的paf范围为70 90hz ，这与实际的雌、雄虫求偶鸣声的pm变化范围是一致的；雌、雄虫能对mvf变化范围较大的信号敏感，雄虫敏感的mvf范围为100 300hz ，与雌虫求偶呜声的mvf变化范围是一致的，而雌虫敏感的mvf范围为200 1700hz ，要比实际的雄虫求偶鸣声的mvf变化范围大的多。 |
