[Aim] To better understand how to control Parlatoria oleae (Colvee) invasion, its morphological characteristics were examined as well as its distribution, host, natural enemy, and biological and economic importance.[Method] Microscope analysis was used to examine the morphology and measure the species characteristics.[Result] Female shells of P. oleae was approx 0.77 mm, and adult female approx 0.55 mm. The body of P. oleae was purple, and the pygidium was yellow. There were small duct tubercles and a curve long hair. There were four lobes with the medial lobe being the largest, and the second and third lobes were similar. The fourth lobe was dentate and had 5 perivulvar pores.[Conclusion] With the high reproductive ability and the variety host, once P. oleae invade a new area, it can make serious damage to an ecosystem. Strengthening the inspection and quarantine is one of the main measures to prevent P. oleae, and biological and chemical measures are also important methods to control P. oleae.
