摘要：
Populations of twospotted spider mites infest peach plant introduction lines at different levels under field conditions in late season sampling in North Carolina. Leaf injury ratings based on a 1-5 scale showed wide differences in plant response to mite feeding among the lines. However, mite fecundity in laboratory tests was highly variable, and no significant differences among lines were found. These results suggest variability in the phenotypic response of peach germplasm to mite population development and effects of feeding.
