Descrição da doença
Chaetocnema tibialis, commonly known as the chard flea, is a small beetle of the family Chrysomelidae. This insect goes through four main stages of development: egg, larva, pupa and adult. Adults are small, shiny black, and have the ability to jump, giving them their common name. Females lay their eggs in the soil near host plants. The larvae emerge from the eggs and feed on the underground roots and stems of plants. After several weeks, the larvae pupate in the soil, later emerging as adults. Adults feed mainly on leaves, leaving characteristic small holes. In temperate climates, Chaetocnema tibialis can have several generations per year, which facilitates its rapid proliferation and continuous damage to chard crops.

Descrição do patógeno
In chard, infestation by Chaetocnema tibialis causes a disease known as chard flea. This pathogen affects both young seedlings and adult plants, causing significant damage to the leaves and, in severe cases, the roots. Foliar damage is particularly problematic as it reduces the photosynthetic capacity of the plant and can render the leaves unsuitable for sale or consumption.
• Small irregular holes in the leaves.
• Leaves with a sifted appearance.
• Reduction in photosynthetic capacity.
• Weakened seedlings with slow growth.
• Damage to roots and underground stems.
• Loss of general vigor in the plant.

Recomendações
• Carry out crop rotations to interrupt the beetle's life cycle.
• Maintain cleanliness of the field, eliminating crop remains and weeds that could serve as shelter for adults.
• Implement physical barriers such as mesh or covers to protect young seedlings.
• Use sticky traps to monitor and reduce the adult population.
• Encourage the presence of natural enemies, such as parasitoid wasps and insectivorous birds.
• Apply biological insecticides based on Bacillus thuringiensis or neem in early stages of infestation.
• Apply chemical insecticides as a last measure, following local recommendations and rotating products to avoid the development of resistance.
• Maintain adequate watering to strengthen plants and make them less susceptible to damage.

RECOMMANDATIONS
- Check the back of the leaves frequently, especially in dry weather.
- Spray water on the leaves to increase humidity and prevent them from settling.
- Keep plants healthy with good watering and adequate light.
- If you see cobwebs or damage, clean the leaves with a damp cloth or pressurized water.
- Use potassium soap or neem oil every few days until they disappear.
