Coccoidea are some of the most potentially detrimental pests for agriculture and ornamental plant industries worldwide, including in Laos. Between January 2015 and August 2016, scale insects were collected on variety of hosts. Previously, the known Coccoidea fauna of Laos comprised 35 species. These most recent collections boost the tally to 49 species belonging to 5 families of Coccoidea. Among these, 19 species are here recorded from Laos for the first time: [Coccidae] Ceroplastes floridensis,Ceroplastes rubens, Coccus capparidis, Drepanococcus chiton, Megapulvinaria maxima, Pulvinaria psidii, Saissetia coffeae; [Diaspididae] Aonidiella citrina, Aonidiella inornata, Fiorinia coronate, Lepidosaphes tokionis, Parlatoria proteus; [Lecanodiaspididae] Psoraleococcus multipori; [Monophlebidae], Icerya aegyptiaca; [Pseudococcidae], Phenacoccus madeirensis, Planococcus ficus, Pseudococcus aurantiacus, Pseudococcus baliteus and Rastrococcus jabadiu. All of these newly recorded species occur elsewhere in south-east or east Asia, including countries contiguous with Laos.
