ScaleNet includes hosts in 11 plant families from the Australasian, Nearctic and Palaearctic zoogeographic regions. A few other species of Pulvinaria have been taken in quarantine in addition to P. floccifera (Westwood), P. hydrangeae, P. ixorae Green, P. polygonata Cockerell, P. psidii Maskell and P. urbicola Cockerell including: P. aurantii Cockerell (Japan, on Citrus); P. citricola Kuwana (Ecuador, on Musa; Japan, on Diospyros); P. elongata Newstead (Colombia, on Oryza ); P. horii (Kuwana) (Japan, on Acer); P. neocellulosa Takahashi (India, on Murraya); and Pulvinaria vitis (Canada, on Tilia).
