  • Notes: In this study, the results of recent surveys (during the period between 2012 and 2015) on alien insects infesting ornamental plants in Bulgaria are reported. Fourteen species, associated with urban landscape areas and indoor plants, are discussed. Two of them, Ceroplastes sinensis Del Guercio and Lepidosaphes flava (Signoret), are reported for the first time in Bulgaria. Furthermore, Acizzia jamatonica (Kuwayama), Ceroplastes ceriferus (Fabricius), Pseudaulacaspis pentagona (Targioni Tozzetti) and Cydalima perspectalis (Walker) have been found in new localities. Metcalfa pruinosa Say has widened its host range in Bulgaria. Additional distribution data are also provided about Aulacaspis yasumatsui Takagi and Cacoecimorpha pronubana (Hübner). Details on current status, host plants, zoogeographical origin and probable pathways of introduction into Bulgaria are reported for each species. Morphological and biological remarks are given for C. perspectalis and C. sinensis.
