WHO CAUSES IT?
Phyllocnistis citrella, Liriomyza sp. and Lyonetia sp. They are genera of leafmining insects, known for their ability to infest various plants. These insects have a complex life cycle that involves several stages. Adult females lay their eggs on the surface or within the tissues of the leaves. Once the larvae emerge, they begin feeding on the inner tissue of the leaf, creating meandering galleries visible on the surface. The larvae go through several molts as they feed and grow inside the leaf. Upon reaching maturity, the larvae pupate inside the leaf or in the surrounding soil. The adults emerge from the pupae, ready to reproduce and continue the cycle. This process can be repeated several times a year, especially in warm climates, allowing leafminer populations to increase rapidly.

SYMPTOMS
The disease caused by leafminers on plants results in a series of characteristic symptoms due to the larvae feeding on leaf tissues. This not only reduces the photosynthetic capacity of plants, but also weakens them and makes them more susceptible to other diseases and environmental stresses.
- Appearance of serpentine and translucent galleries in the leaves.
- Discoloration and yellowing of affected leaves.
- Premature fall of severely damaged leaves.
- Reduction in the general vigor of the plant.
- Black or brown Taches on the leaves, indicative of larval feeding areas.
- Curling and deformation of the leaves.
- Presence of pupae on the lower surface of the leaves or on the nearby soil.

Recommendations
- Regularly inspect plants for early signs of infestation and manually remove affected leaves.
- Use yellow sticky traps to monitor and reduce the adult population.
- Apply specific insecticides for leafminers, following the manufacturer's recommendations and alternating products to avoid the development of resistance.
- Introduce and encourage the presence of natural enemies of leafminers, such as parasitoids and predators, which help control larval populations.
- Maintain adequate hygiene in the growing area, removing and destroying plant remains that may harbor pupae or adults.
- Avoid excessive use of nitrogen fertilizers, as they can promote the growth of tender shoots that are more susceptible to attack by leafminers.
- Implement cultivation practices that strengthen plant health, such as adequate irrigation and selective pruning.

RECOMMENDATIONS
- 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.
