蚁属(膜翅目:蚁科)4种的形态测量学分析

摘要

运用形态测量学分析方法,对蚁属Formica中的光亮黑蚁F.candida、亮腹黑褐蚁F.gagatoides、北京凹头蚁F.beijingensis和满洲蚁F.manchu 4种共296头蚂蚁标本进行研究.选取头长(HL)、头宽(HW)、复眼最大直径(ED)、触角柄节长(SL)、并腹胸长(AL)、前胸背板宽(PW)、并胸腹节宽(DPW)和体长(TL)8个度量数据为变量进行相关性、配对T检验、均值±SD与主成分散点分布图分析,探讨形态测量学方法在蚁科昆虫分类中的应用.结果表明:形态测量学方法能够将4种蚂蚁进行有效识别区分,可作为形态分类学研究的一种有效、快速的辅助方法.%Using morphometric method to measure eight morphological characteristics (i.e.head length (HL),head width (HW),eye maximum diameter (ED),scape length (SL),alitrunk length (AL),pronotal width (PW),dorsal propodeal width (DPW),and total length (TL)),of four species of the genus Formica (F.candida,F.gagatoides,F.beijingensis,and F.manchu).Correlation,paired T test,mean value ± SD,skewness and kurtosis,and principal component were analyzed.The rusults showed that morphometric analysis method can distinguish the four species from one to another,and offer an effective and fast method for morphological taxonomy.
