Abstract：
[Objectives] To determine whether Planococcus vovae (Nassonov, 1909) is synonymous with Planococcus juniperus Tang, 1989 or a new invasive pest in China. [Methods] In addition to comparing the morphology of adult females collected from Beijing and Inner Mongolia, new sequences in the HCO-LCO region of the COI gene were compared to those in NCBI using the Basic Local Alignment Search Tool (BLAST. Phylogenetic trees were then constructed using the Bayesian inference and Maximum likelihood methods, and the genetic distance between the COI sequences of different specimens was calculated. [Results] Many morphological differences are apparent between adult females from Beijing and those from Inner Mongolia. COI consistency between specimens from Beijing and Inner Mongolia, and between specimens from Beijing and French P. vovae, are 99.85% and 95.13%, respectively. Beijing specimens and P. vovae from France and Spain clustered in a single clade on two phylogenetic trees and had a genetic distance of 0.In contrast, there is a genetic distance of 0.05 between European specimens and those from from Inner Mongolia. [Conclusion] P. vovae is not synonymous with P. juniperus Tang and is therefore a new invasive pest in China.
