中文摘要:
为探讨群居型西藏飞蝗Locusta migratoria tibetensis Chen地理种群数量性状关系,从青藏高原9个地区采集到不同地理种群,以数值分析对形态指标及其比值进行了分析。结果表明,前翅长度(E)、后足股节长度(F)、头宽(C)形态指标和E/F、F/C两个比值可以作为分析种群关系的参数。聚类分析和主成分分析结果相似,能够较好地说明青藏高原9个种群的地理变异和种群相互关系,9个地理种群可以分三个类群,即第Ⅰ类群包括百巴 (BB)与八美 (BM)种群;第Ⅱ类群包括普兰 (PL)、扎囊 (ZN)、洛须 (LX)种群;第Ⅲ类群包括噶尔 (GE)、香孜 (XZ)、日土 (RT)、那嘎 (NG)种群。
英文摘要: A morphological index was used to quantify the morphological similarity 9 geographical populations of the gregarious phase of Locusta migratoria tibetensis Chen. The morphological indicators eleytron length(E), femur length(F), maximum width of head(C), and the ratio E/F, F/C, can be used as morphological markers to determine the relationship between geographical populations. The results obtained by two different statistical methods were similar, which suggests this method is an improvement in analyzing relationships between geographical populations of locusts. The 9 geographical populations were divided into three groups; the first including the Bai ba (BB) and Ba mei (BM) populations. The second group included the Pu lan (PL), Zha nang (ZN), Luo xu (LX) populations. The third group included the Ga er (GE), Xiang zi (XZ), Ri tu (RT) and Na ga (NG) populations.
