WHO CAUSES IT?
Pegomya betae, known as the beet fly, is a dipteran of the Anthomyiidae family. Adults emerge in early spring and are characterized by their light gray color and translucent wings. Females lay their eggs in the soil near the base of beet plants. Once the eggs hatch, the larvae, which are creamy white in color, begin feeding on the roots and leaves of the plant. This larval damage is especially damaging as the larvae excavate galleries in the roots, making it difficult to absorb water and nutrients. The larvae go through several stages of development before pupating in the soil. Adults emerge after a week to ten days, ready to repeat the cycle. The number of generations can vary from two to five per year, depending on climatic conditions.

- Delayed growth
- Leaf wilting
- Deformations in the roots
- Reduction of root mass
- General yellowing of the plant
- Low absorption of nutrients and water
