Spider Mites on Common Hazel

Corylus avellana L.

Damage to common hazel caused by members of the Tetranychidae family, resulting in the appearance of light spots on leaves, yellowing, web formation, and premature leaf drop.

In the reference 12 varieties crop Common hazel, where this is mentioned in the description.

Various mite species from the Tetranychidae family parasitize common hazel (hazelnut), with Tetranychus urticae being the most prevalent. The presence of Tetranycopsis horridus, T. viennensis, Eotetranychus coryli, Panonychus ulmi, and Bryobia rubrioculus is also recorded on the crop.

Initial symptoms of infestation appear as small light spots on the underside of the leaf blade at the feeding sites. As the population grows, the leaves acquire a marbled or bronze hue and become covered in thin webbing, which, in cases of severe infestation, leads to wilting and premature defoliation.
