Abstract
Among scab-resistant apple cultivars, good hosts for the hawthorn spid er mite, Tetranychus viennensis Zacher, and for the two-spotted spider mite, Tetranychus urticae Koch (Acari, Tetranychidae), were Novamac a nd Freedom, on the leaves of which the net reproduction rate (R-o) ran ged between 20 and 26, while the worst hosts were the cvs. Primula, Pi onier, and Lodel, on the leaves of which the R-o index ranged from 8.9 1 to 15.92.
