WHO CAUSES IT?
Chaetocnema tibialis, known as the beet flea, is a small beetle that belongs to the Chrysomelidae family. This insect has a shiny, oval black or dark brown body, with hind legs adapted for jumping, giving it its common name. The adults emerge in spring and feed on the young leaves of the beet, creating small holes. Females lay eggs in the soil near the base of plants. The larvae emerge and feed on the roots and underground tissue of the plants. After completing their development, the larvae pupate in the soil, giving rise to the next generation of adults. This cycle can repeat several times during the growing season, especially under favorable temperature and humidity conditions.

SYMPTOMS
Chaetocnema tibialis infestation in beets causes a disease known as flea beet, which mainly affects the leaves of the plant. Damage is caused by both adults and larvae, although the adults are the most damaging. Small and numerous perforations are observed in the leaves, which can reduce the photosynthetic capacity of the plant and weaken its growth.
- Small rounded perforations on the leaves
- Decrease in photosynthetic capacity
- Reduced growth and general weakening of the plant
- Sheets with sieving appearance due to perforations
- Loss of vigor and productivity of the crop
- Increased susceptibility to other pests and diseases
