中文摘要：
【目的】 明确热带平刺粉蚧Rastrococcus tropicasiaticus Williams的鉴别特征，建立平刺粉蚧属种类检索表。【方法】 随机抽样、形态学观察和测量。【结果】 从进口越南龙眼鲜果中截获热带平刺粉蚧，头胸部腹面多格腺以单排排列，体背面大五格腺少是其识别的主要形态学特征；编制了平刺粉蚧属16种检索表。【结论】 热带平刺粉蚧为我国口岸首次检出，研究结果为进口水果中该类粉蚧的检疫鉴定提供了重要的参考资料。
英文摘要：
[Objectives] To understand the morphological characteristics of Rastrococcus tropicasiaticus Williams and develop a taxonomic key to identify Rastrococcus species in the Oriental region. [Methods] Random sampling, morphological observation and microscopic measurement were used to develop a quarantine and morphological identification method for the R. tropicasiaticus. [Results] The taxonomic key developed in this study was instrumental to the first identification and interception of R. tropicasiaticus on longans imported from Vietnam. Single rows of ventral multilocular disc pores on the head and thorax and a few large dorsal quinquelocular pores were the diagnostic morphological characteristics used to identify this species. [Conclusion] The key developed in this study can reliably identify R. tropicasiaticus and should therefore contribute to improved quarantine and identification of this pest.
