Clones of beach strawberry, Fra˜aria chiloensis (L.) Duchesne, and the cultivated strawberry, Fragaria x ananassa Duchesne 'Totem,' varied in suitability for survival and oviposition of the twos potted spider mite, Tetranychus urticae Koch. Strawberry clones also differed in densities of glandular and nonglandular trichomes and concentrations of total and catechol-based phenolics. A negative relationship observed between mite survival and the density of glandular trichomes may have resulted from entrapment of mites by sticky exudates from glandular trichomes. Mite oviposition was negatively correlated with densities of glandular and nonglandular trichomes and the concentration of total foliar phenolics. However. mite oviposition was best described by a model that combined three interacting morphological and chemical characteristics of the strawberry plant rather than by any individual characteristic.
