摘要
北京地区蟪蛄蝉（ＰｌａｔｙｐｌｅｕｒａｋａｅｍｐｆｅｒｉＦａｂｒｉｃｕｒｓ）的呼叫声和求爱声具有不同的声学特性和行为功能。呼叫低潮声“Ｚｈｉ－”声和呼叫高潮声“Ｚｈｉ－”声分别由不规则和规则调幅脉冲组成，声响效果主要取决于主频率分别为７３００±６１Ｈｚ和５８１９±３８Ｈｚ的载频带。雌蝉大范围内的飞行趋声反应主要与呼叫高潮声载波的主频特性有关。求爱低潮声“Ｏｕ－”声和求爱高潮声“ＺｈｉＯｕ－”声都是由明显失去调幅特性的脉冲组成，声响效果主要取决于基频分别为５２２±９Ｈｚ和５９４±１２Ｈｚ的基频带。小范围内的求爱主要与求爱高潮声基频所表征的脉冲时间参数有关。发声机制主要与发声膜结构相适应的三条长肋的激励方式有关。
in the kaempfer cicada(Platypleura Kaempferi Fabricurs) in Beliing region, the calling andcourtship song possess different acoustic properties and behavioral significances. the calling soft-song'zhi-' sounds and loud-song 'Zhi-' sounds are separately composed of irregular and regular amplitudemodulating pulses, and the principal frequencies of the carrier band mainly respollsible for the soundingeffects are 7300 ± 61 Hz and 5819 ± 38 Hz, respectively. The flight phonotactic reactiolls of femalecicadas in long range are mainly relevant to the carrier-frequency property of calling loud-songs. Thecourtship soft-song 'Ou-' sounds and loud-song 'ZhiOu-' sounds consist both of pulses withoutmarked amplitudes-modulation properties, and t he fund ame nt al frequenc ies of t he b asic band mainlyresponsible for the sounding effects are 522 1 9 Hi and 594 1 12 Hi, respectively. The short-rallgecourtship of female cicadas is mainly relevant to the temporal pattern characterized by fundamentalfrequencies of the courtship loud-song. The sound-production mechanism is discussed in relation toexciting modes of three long ribs corresponding to structures of the sounding membrane.
