QUI EN EST LA CAUSE ?
Thrips are small winged insects belonging to the order Thysanoptera, known for their ability to cause significant damage to a wide variety of plants. These insects have thin bodies and narrow wings fringed with hairs. They feed by piercing the surface of leaves and sucking plant juices, which can weaken plants and cause growth deformities.

In ornamental and garden plants, thrips can cause a disease known as "leaf silvering." Symptoms include silvery or whitish Taches on leaves, caused by damage by thrips while feeding. Additionally, deformed or curled leaves may be observed, and in severe cases, defoliation may occur.
