WHO CAUSES IT?
Tetranychus urticae, commonly known as spider mite, is a tiny mite that infests various plants. Adult females deposit their spherical, transparent eggs on the lower surface of the leaves. These eggs hatch within a few days, giving rise to six-legged larvae that quickly transform into eight-legged nymphs. Nymphs go through two instars before becoming adults. This development can be completed in less than a week under favorable conditions, allowing spider mite populations to multiply rapidly. Adult females, reddish or greenish-yellow in color with two dark dorsal Taches, can live for several weeks, during which they lay hundreds of eggs, thus ensuring the continuity of the infestation.

SYMPTOMS
Infestation by Tetranychus urticae in plants causes the disease known as red spider, which weakens and severely damages plants. These mites feed by sucking the cellular contents of the leaves, which reduces the photosynthetic capacity and causes considerable stress in the plants. Symptoms of this disease include:
- Appearance of yellow or tan Taches on the leaves.
- Discolored and dry leaves.
- Mottled or spotted leaf tissues.
- Premature loss of leaves.
- Reduction of plant vigor and growth.
- Presence of fine cobwebs on the underside of the leaves and between the shoots.
- Visible damage to shoots and fruits, especially in cases of severe infestations.
