利用蝗虫阳具基背片形态学数据进行种下研究初探

Preliminary Study on Intraspecies Used Iphauus’s Morphological Date

利用显微拍摄技术拍摄不同地理种群青脊竹蝗(Ceracris nigricornis nigricornis)和大青脊竹蝗(ceracris nigricornis laeta)的阳具基背片照片,测量8个变量,并将得到的数据进行主成分分析,接着利用主成分数据再进行聚类分析。结果表明:利用阳具基背片形态数据基本可以区分青脊竹蝗和大青脊竹蝗,但种内地理种群的区分有待进一步研究。

Used the microscopic photography technology to photograph different geography populations of Ceracris nigricornis nigricornis and ceracris nigricornis laeta's epiphallus pictures,measured eight variables,and obtained the data to carrid on the analysis of principal components,then carried on the cluster analysis using the date of principal components.The result indicated:Basically distinguished Ceracris nigricornis nigricornis and ceracris nigricornis laeta using epiphallus's morphological data,but the discrimination of intraspecies geography population waited to be studyed further.
