WHO CAUSES IT?
Lixus junci and Lixus scabricollis are beetles of the Curculionidae family, known for their ability to infest beet crops. Adults emerge in early spring and feed on the young leaves and stems of plants. The females lay their eggs inside the beet stem, where the larvae develop. The larvae excavate galleries in the stems and roots, feeding on internal tissue and causing extensive damage. These galleries interfere with the transport of nutrients and water within the plant, weakening it significantly. After several weeks, the larvae complete their development and pupate within the galleries. The adults emerge at the end of summer, thus completing the cycle. This cycle can repeat several times a year, depending on weather conditions, allowing Lixus populations to increase rapidly.
