Studies of the Coccoidea. 12. Species occurring on deciduous fruit and nut trees in Queensland

Abstract

Thirty species of scale insects have been recorded from deciduous fruit and nut trees in Queensland. At least 26 are importations.
Thirteen of the species are on record from the Stanthorpe district, the main deciduous fruit growing area of the State. In that area, however, only five occur on deciduous fruit trees: two, Quadraspidiotus perniciosus (Comstock) and Eulecanium persicae (F.), particularly the former, are of economic importance.
