Mites
Mites are arachnids that are mostly found on the underside of leaves. Through their bite-sucking mouth armor they preferentially feed on the leaves, causing speckled discolorations resulting from the bites. The presence of mites affects the photosynthetic efficiency and transpiration of the plant, causing the yellowing and dryness of the leaves, which is reflected in the vigor of the vine and in the quality of production.
Economic Attack Level (NEA)
* As erinosis is considered an occasional pest in the vineyard, there are no official economic levels of attack, nor sampling procedures to assess the intensity of attack for erinosis.
