| 摘 要： | 录制分析了陕西省三种常见蟋蟀的雄性鸣声特征.结果表明:贝氏斗蟋鸣声中一个音节所含脉冲数不等,多为8或9个,音节持续时间较长(约203 ms),主峰频率为4472Hz;长鄂斗蟋鸣声中一个音节所含脉冲数多为8个,主峰频率为4162 Hz;多伊棺头蟋鸣声的时域波形较为规则,每个音节皆由2个脉冲组成,音节持续时间较短(约32 ms),主峰频率为4810 Hz。两种斗蟋的鸣声表现出一定的相似性和不同之处,而与多伊棺头蟋鸣声的差别较明显。鸣声之间的差异可以作为种类鉴别的依据。

| Abstract: | In the present paper the male calling songs of three common species of crickets in Shannxi province are recorded and their characteristics are analyzed.The results show that the calling song of Velarfictorus beybienkoi(Gorochor) have various number of pulses in one syllable,mostly 8 or 9,and long syllable duration time(203ms or so).The main peak frequency is 4472 Hz.In the calling song of Velarificatorus asperses(Walker) the number of pulses in one syllable is mostly 8 and the main peak frequency is 4162 Hz.The calling song of Loxoblemmus doenitzi(Stein) is regular with two pulses in one syllable,short duration time(32ms or so) and the main peak frequency 4810 Hz.The songs of two species of crickets of the genus Velarifictorus show certain similarities and differences and are significantly different from the calling song of Loxoblemmus doenitzi.Differences in these song characteristics can work as the basis of taxonomy. |
