中文摘要：
【目的】 提供仙人掌粉蚧Pseudococcus nakaharai Gimpel & Miller的鉴定方法，填补国内尚无该虫研究报道的空白。【方法】 显微玻片制作、形态特征分析、测量和二歧法检索。【结果】 详细描述了仙人掌粉蚧的形态特征和结构测量值，提出其鉴别特征，构建与近似种的检索表；提供了仙人掌粉蚧寄主和分布情况、田间特征照片、显微特征图片。【结论】 仙人掌粉蚧为我国口岸首次检出，研究结果可为进口仙人掌科、天南星科等植物产品或种苗携带该类蚧虫的检疫鉴定提供参考。
英文摘要：
[Objectives] To provide a guide to the morphological identification of Pseudococcus nakaharai Gimpel & Miller, a species not previously reported in China. [Methods] Slide-mounted specimens, morphological analysis, micrometer measurements and dichasial taxonomy retrieval were used to find morphological criteria that can reliably identify P. nakaharai. [Results] A detailed description and structural measurements of adult female P. nakaharai, congeners, hosts, and the species’ distribution, are provided, as well as a key to adult females of P. nakaharai and similar species. [Conclusion] The information presented in this paper following the first detection of P. nakaharai in China should improve the future quarantine and identification of this pest.
