Title: Variability in Resistance of Peach Plant Introductions to Tetranychus urticae (Acari: Tetranychidae) Infestation
Authors: R.L. Meager Jr. and D. Werner
Abstract:
Populations of twospotted spider mites infested 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.
