Malumphy, C.P., & Redstone, S. 2011 First Incursion of Smooth Pine Scale Leucaspis pini (Hartig) Hem., Diaspididae) in Britain, with a Review of the Status of Leucaspis in Britain.. Entomologist's Monthly Magazine 147:69-75
Notes: In November 2010, a large infestation of smooth pine scale Leucaspis pini (Hartig) (Hemiptera: Diaspididae) was found on a single potted 2m tall Scots pine Pinus sylvestris L. plant grown outdoors at the Royal Botanic Gardens, Kew, Surrey, England. The infested plant had been used in a temporary exhibition at the gardens four or five years previously but its origin is not known for certain. It is suspected to have been bought from a commercial plant nursery in southern England. This is the first known incursion of smooth pine scale in Britain and the infested tree has since been destroyed. The biology and geographical distribution of L. pini] are discussed. In addition, the records of five other nonnative species of [Leucaspis recorded in Britain are reviewed. Only one species, L. podocarpi Green, is currently naturalised in Britain and is restricted to Podocarpus spp. on Tresco, Isles of Scilly, Cornwall.
