Final diagnosis


Colomerus vitis (Grape erineum mite)

Attack of <b> <i> Colomerus vitis </i> </b> on young leaves of the apex of a vine branch. Leaf galls are more numerous and extensive. (Erinosis)
Attack of <b> <i> Colomerus vitis </i> </b> on young leaves of the apex of a vine branch. (erinosis)
The limbus is deformed where <b> <i> Colomerus vitis </i> </b> has made its nutritional punctures: the formation of these small domes is characteristic of erinosis.
Sometimes galls caused by <i> Columerus vitis </i> can occupy a significant area of ​​the leaf surface: <b> Erinose </b>
In the event of severe attack by <b> <i> Colomerus vitis </i> </b>, the entire surface of the leaf may be blistered and a whitish down appears on the upper surface.
On the underside of the leaf, the enlarged hairs form a down at the stings of <b> <i> Colomerus vitis </i> </b>, the agent of erinosi
Magnifying glass of the hypertrophy of the hairs on the underside of the leaf caused by bites of the <em> Colomerus vitis </em> mite.
Symptom of erinosis on vine leaves at the end of the vegetative cycle. The enlarged hairs take on a reddish to brown tint. <b> <i> Colomerus vitis </i> </b>
Mobile stage of <em> Colomerus vitis </em> circulating in the hair of the galls, the body is pale yellow.
We can distinguish hypertrophied hairs in an erinose gall at the end of the vegetative cycle: <b> <i> Colomerus vitis </i> </b>
