In commercial orchards, C. verbasci was ranked among the top three pests in 22 of 40 samples collected at harvest, and its damage exceeded the economic injury level of 1% culled apples in 17 of the samples. Injury was greatest in "Delicious" cultivars, for which a linear relationship was derived between population density and damage at harvest. Economic injury levels of one and four nymphs per tap are proposed for cvs. Golden and Red Delicious, respectively, in British Columbia.
