WHO CAUSES IT?
Cassida vittata, commonly known as the beet cassid, is a beetle insect of the family Chrysomelidae. This insect goes through several stages during its development: egg, larva, pupa and adult. Adults emerge in the spring and begin feeding on sugar beet leaves. Females lay their eggs on the underside of leaves. After hatching, the larvae feed on the leaf tissue, creating galleries and causing significant damage. The larvae go through several molts before pupating in the soil or at the base of plants. After completing the pupal stage, new adults emerge and can continue feeding until the arrival of winter, at which time they seek shelter in the soil or surrounding vegetation to hibernate. The ability of this insect to produce several generations per year and its ability to hibernate allow it to survive in different environmental conditions and represent a constant challenge for crop management.

SYMPTOMS
Cassida caused by Cassida vittata severely affects sugar beet, compromising its growth and yield. The damage is mainly foliar, which reduces the photosynthetic capacity of the plant and affects its general development.
- Presence of holes and galleries in the leaves.
- Wearing of the leaf tissue, leaving only the main veins.
- Leaves with a skeletal appearance.
- Decrease in leaf surface useful for photosynthesis.
- Reduction in plant vigor.
- Loss of yield in beet cultivation.
- General weakening of the plant, making it more susceptible to other pests and diseases.
