摘要
研究结果表明，朱砂叶螨Tetranychuscinnabarinus（Boisduval）体型大小的差异不能反映其地理分布的规律，也不能作为它与有关近似种相区分的特征；雌成螨足Ⅰ胫节刚毛数量的变化并不代表各地理种群之间的稳定变异，但可作为辅助鉴别特征；不同地理科群及同一种群不同个体之间阳具端锤形状存在一定差异，但仍可作为朱砂叶螨有效的鉴别特征。
An attempt was made to examine the morphologic variations of different geographic populations of (Tetranychus cinnabarinus(Boisduval) ). Results showed that the bodysize difference did not reflect the geographic distribution pattern and was hence not valuable in distinguishing T. cinnabarinus from its sibling species. The number of Leg I tibiala of the female adults Varied but irregularly among geographic populations,and it can,however,be used for supplementary identification. The shape and size of the aedeagal terminal knob differed to a certain extent among different geographic populations and evenindividuals of the same plpulation but were still effective characteristics for identificationof T. cinnabarinus.
