Colonization Sites of Scale Insects (Homoptera: Coccoidea) on Different Plant Species and Varieties
Three groups of scale insects living on wooden plants can be distinguished considering the parts of plants on which they can reproduce. Sphaerolecanium prunastri and Epidiaspis leperii infest branches only, while Parthenolecanium corni (L1) attacks also the leaves. The San José scale lives on all parts of the plants except the roots. Significant differences have been found in the intensity of San José scale infestation between trunks, branches and fruits of susceptible apple varieties (Húsvéti Rozmaring, Jonathan, Starking, Golden Winter Parmen).
