Labanowski, G.S. 1999 [Scale insects - dangerous pests of Dracaena.] Tarczniki - grozne szkodniki draceny.. Ochrona Roslin 43(6): 14-15.

Notes: Two diaspidid species, Chrysomphalus aonidum and Pinnaspis aspidistrae, are regularly imported into Poland on decorative pot plants, including Dracaena marginata, Aralia sieboldii [Fatsia japonica], Citrus spp., Ficus spp., Monstera deliciosa, Photinia serrata, Strelitzia sp. and others. They quickly spread in commercial greenhouses and cause serious damage to a variety of ornamentals. The life cycle of both pests is described and their photographs are shown. Actellic 500 EC [pirimiphos-methyl], combined with the wetting agent Citowett AL, are recommended for chemical control.
