Popis: An outbreak of Hydria prunivorata (Ferguson) in north-central New York resulted in severe defoliation of black cherry, Prunus serotina Ehrh. from 1969–1971. Black cherry mortality caused by a scolytid, Phloeotribus liminaris (Harris), following defoliation was concentrated in areas with similar stand and soil characteristics. Polar ordination of 10 forest stands based on pre-mortality tree species composition grouped areas with high mortality. Mortality was significantly correlated with the relative importance value of black cherry in the stand and with the hydrogen ion concentration of the soil. Soil p H was lowest on poorly drained sites.
