Since 2001, all scale insects inspected from the imported agricultural products by Bureau of Animal and Plant Health Inspection and Quarantine (BAPHIQ), Council of Agriculture, Executive Yuan, Taiwan, were sent to Taiwan Agricultural Research Institute (TARI) for identification. A total number of 2110 scale samples were inspected during 2001-2010. The results showed that 2037 samples of them belonging to 59 species of 36 genera in 7 families of Coccoidea (Hemiptera: Sternorrhyncha) were identified, in which 11 species of 9 genera have no records in Taiwan, including Asiacornococcus kaki (Kuwana in Kuwana & Muramatsu, 1931), Diaspidiotus ostreaeformis (Curtis, 1843), Exallomochlus camur Williams, 2004, E. hispidus (Morrison, 1921), Lepidosaphes conchiformis (Gmelin, 1790), Lomatococcus ficiphilus (Borchsenius, 1960), Matsucoccus matsumurae (Kuwana, 1905), Paraputo odontomachi (Takahashi, 1951), Pseudococcus baliteus Lit, 1994, Ps. jackbeardsleyi Gimpel and Miller, 1996, and Unaspis yanonensis (Kuwana, 1907) (a quarantine pest).
