Morphological characters are measured from each tick specimen from samples of 10 "populations" of Haemaphysalis longicornis. The 10 populations consist of 6 diploid bisexual and 4 triploid parthenogenetic populations from Australia, Japan, and Korea. Statistical analyses (univariate and multivariate) of differential morphological variation are made among sex, method of reproduction, and chromosome ploidy level in attempts to determine the effects of these parameters on overall variation. In general, laboratory-reared thelytokous females (3n = 33y are least variable, laboratory-reared bisexual females and males (2n = 22 female; 21 male) are intermediate in variation, and field-collected bisexual males and females are most variable. However, the only field-collected thelytokous "population" (3n = 33) in the analyses is more variable than even the field-collected bisexual ticks.
从长角血蜱10个“种群”样本中的每个蜱虫标本测量形态特征。这10个种群包括来自澳大利亚、日本和韩国的6个二倍体两性种群和4个三倍体孤雌生殖种群。对性别、繁殖方式和染色体倍性水平之间的差异形态变异进行统计分析（单变量和多变量），以确定这些参数对总体变异的影响。一般来说，实验室饲养的产雌孤雌生殖雌性（3n = 33）变异最小，实验室饲养的两性雌性和雄性（2n = 22雌性；21雄性）变异程度中等，而野外采集的两性雄性和雌性变异最大。然而，分析中唯一野外采集的产雌孤雌生殖“种群”（3n = 33）甚至比野外采集的两性蜱虫变异更大。
