历山自然保护区四种蟋蟀鸣声结构的比较研究(直翅目:蟋蟀总科)

COMPARATIVE STUDIES ON THE SONG STRUCTURES OF FOUR SPECIES OF CRICKETS FROM LISHAN NATURE RESERVE (ORTHOPTERA:GRYLLOIDEA)

应用计算机技术 ,分析了山西历山自然保护区的白须双针蟋、短翅灶蟋、银川油葫芦、迷卡斗蟋 4种蟋蟀雄性的鸣声结构。白须双针蟋雄性鸣声的每个脉冲组持续时间和每个脉冲组的脉冲数不同 ,主能峰频率为 6 5kHz。短翅灶蟋雄性鸣声的时域波形较规则 ,每个脉冲组由 3个脉冲构成 ,每个脉冲组的持续时间、脉冲组间隔基本相同 ,主能峰频率 6 6kHz。银川油葫芦雄性的鸣声由两类脉冲组构成 ,主能峰频率为 3 94kHz。迷卡斗蟋雄性鸣声的时域波形较规则 ,每个脉冲组由 6～ 7个脉冲构成 ,主能峰频率为 3.86kHz。

The paper analysed the male song structures of four species of crickets from Lishan Nature Reserve.The chirp duration and the number of the pulses in a chirp is different in the male songs of Dianemobius furumagiensis (Ohmachi & Furakawa,1929) from that of the other three species and the frequency of highest power peak is about 6.5*!kHz.The male songs of Gryllodes sigillatus (Walker,1869) are regular. A chirp of the songs consists of 3 pulses.The frequency of highest power peak is about 6.6*!kHz. The sequences of the male songs of Teleogryllus infernalis (Saussure,1877) have two types of chirps. The frequency of highest power peak is about 3.94*!kHz. The songs of male of Velarifictorus micado (Saussure,1887) have several sequences, a chirp with 6-7 pulses. The frequency of highest power peak is about 3.86*#kHz.
