Pests
Pyrus communis L.
The two-spotted spider mite Tetranychus urticae infests pear trees, causing light-colored stippling, leaf bronzing, and web formation. This leads to impaired photosynthesis, reduced winter hardiness, and premature defoliation.
In the reference 3 varieties crop European pear, where this is mentioned in the description.
Damage on pear trees appears as small light or silvery spots on the underside of the leaf at the pest's feeding sites. As the mite population develops, the spots merge, causing yellowing and bronzing of the leaf blade. A characteristic sign of Tetranychus urticae activity is the presence of fine webbing on the surface of leaves and fruit.
Infestation by spider mites has an indirect negative impact on the overall condition of the tree, reducing its resistance to adverse environmental factors and fungal diseases. No specific races of the pest associated with pear cultivars, nor any breeding resistance genes to this species, have been identified at this time.
