WHO CAUSES IT?
Cassida vittata is a beetle belonging to the family Chrysomelidae, commonly known as cassid. This insect has a flattened, oval-shaped body, with a length that varies between 5 and 7 millimeters. Adults are bright green and have a pronotal shield that covers much of the body, including the legs and head. During the warm months, females lay their eggs on the underside of table beet leaves. After an incubation period, the larvae emerge and begin to feed on leaf tissue. These larvae have a spiny, yellowish body, and go through several stages before pupating. Pupation occurs in the soil or on leaves, where the larvae transform into adults. Depending on environmental conditions, there may be several generations per year, especially in hot climates.

SYMPTOMS
In table beets, infestation by Cassida vittata produces a disease known as cassid. Damage is caused by both adults and larvae, who feed on leaf tissue, creating necrotic areas that interfere with photosynthesis and normal plant growth.
- Presence of irregular holes in the leaves.
- Transparent areas on the leaves due to the removal of the parenchyma.
- Withered and discolored leaves.
- Reduction in the effective leaf surface for photosynthesis.
- Weakened plants and lower root yield.
- Visible presence of adults and larvae on the underside of the leaves.

Recommendations
- Regularly monitor crops to detect the early presence of adults and larvae.
- Implement crop rotation to interrupt the pathogen cycle.
- Promote the presence of natural predators such as parasitoid wasps and birds.
- Maintain field hygiene by eliminating residue from previous crops that may harbor pupae.
- Apply specific insecticide treatments when economic damage thresholds are exceeded.
- Use colored sticky traps to monitor and reduce the adult population.
- Implement physical barriers such as mesh to prevent adults from entering crops.
- Avoid excessive use of nitrogen fertilizers that may favor the development of the pest.

RECOMMENDATIONS
- Check your plants frequently, especially at dawn or dusk.
- Remove the beetles by hand and place them in a container with soapy water.
- Use yellow traps to attract and catch the adults.
- Keep the floor clean and free of old plant remains.
- Apply diatomaceous earth around the base of the plants.
- Spray with wormwood, chili or chili infusion or a solution of baking soda and vinegar to repel them naturally.
- Use light traps or funnel traps to capture them.
- If the attack is very strong, use a specific insecticide.
REPELLENT PLANTS
