WHO CAUSES IT?
Scrobipalpa ocellatella, known as the beet moth, is a lepidopteran of the Gelechiidae family. Adults are small, grayish-brown moths with a wingspan of 10-15 mm and have dark spot patterns on their wings. Females lay their eggs on beet leaves, preferably in young, tender areas. Upon hatching, the yellowish-white larvae with dark heads begin to feed on leaf tissue, undermining the leaves and causing significant damage. The larvae go through several larval stages, increasing in size and changing color to green before pupating. Pupation occurs on the leaf or in the soil near the host plant. The entire cycle, from egg to adult, can be completed in about a month, and the moth can have multiple generations per year, especially in warm climates.

- Brown or necrotic Taches
- Delay in plant growth
- General loss of vigor
- Reduction in root size and quality
- Severe defoliation in cases of high infestations
