Notes: Abstract: In the last fifty years, 14 new non-indigenous scale insect species have spread or were introduced into Slovenia: 7 Coccidae (Ceroplastes japonicus, Coccus pseudomagnoliarum, Neopulvinaria innumerabilis, Pulvinaria fioccifera, P. hydrangeae, Pulvinariella mesembryanthemi, Saissetia coffeae), 3 Diaspididae (Kuwanaspis pseudoleucaspis, Pinnaspis strachani, Pseudaulacaspis cockerelli) and 4 Pseudococcidae (Planococcus ficus, Pseudococcus calceolariae, P. viburni and Spilococcus mammillariae). Neopulvinaria innumerabilis, Ceroplastes japonicus and Pulvinaria hydrangeae are widespread and sometimes serious pests on various crops. Further 4 species were only intercepted during the inspection of imported plants (Aonidiella aurantii, Lepidosaphes beckii, Dysmicoccus brevipes, Ripersiella ficaria). The first record of Ripersiella ficaria on roots of imported bonsai trees of Ligustrum sinense is reported.
