摘要/Abstract

摘要： 北京西郊(BX)、陕西西安(SX)、四川峨嵋山(SE)、山东潍坊(SW)、福建福州(FF)和陕西杨陵(SY)地区蟪蛄蝉鸣声都含高潮声Zhi…”声、脉冲的单一式调幅特性和高潮声的载波主频率(6 433±375)Hz等基本相同，显示种的同一性。但是高潮声的基频和主频率的品质因数(Q_3dB)等显示出不同程度的地区性种下差异。BX、SX和SE的基频相同(550Hz)，都为高Q_3dB，即无明显的地区差异。SW和FF的基频分别为450H2和650Hz，Q_3dB都明显降低，即呈-定的地区差异。SY不仅呈节奏变化的单次声-高潮声-尾声的特有模式，而且基频增高为800Hz，即地区差异更明显。

Abstract: In this paper, the calling songs of kaempfer cicada Platypleura kaempferi(Fabricius) distributing in the western suburbs of Beijing (BX), Xian (Shaanxi)(SX), Mt. Emei (Sichuan) (SE), Weifang (Shandong) (SW), Fuzhou (Fujian)(FF) and Yangling (Shaanxi) (SY) are analyzed. The natural calling songs from thesed ifferent regions all have a high tide sound "Zhi… ', a characteristics of single amplitude modulation of pluses, and the principal frequencies of high tide sound (6 433=375Hz) are the same on the whole. These indicate the specificity of the species. But the fundamental frequencies of high tide sound and the quality factors (Q_3dB) of principalfriquencies show some differences between populations from different regions. The fundamental frequencies of SW and FF are 450 Hz and 650 Hz respectively and the quality factors of principal frequency are lower, showing some regional differences. Especially the fundamental frequency of SY is raised to 800 Hz, namely, the differences between regions are more obvious.

Key words: Platypleura kaernpferi, variations of songs, geographic differences
