DESCRIPTION
WHO CAUSES IT?
Bemisia tabaci, commonly known as whitefly, is an insect belonging to the Aleyrodidae family. This pathogen has a life cycle consisting of four main stages: egg, nymph, pupa and adult. Adult females lay their eggs on the underside of the leaves of host plants. Once they hatch, the nymphs feed on the plants' phloem, causing significant damage. They then go through several instartions before becoming pupae and finally adults. This life cycle can be rapid, with multiple generations per year, especially in warm, favorable conditions.
SYMPTOMS
Whiteflies cause damage to lettuce plants by feeding on the phloem and secreting toxic substances, which can weaken the plants and reduce their ability to grow and produce. General symptoms include the presence of whiteflies flying around the plants and the presence of honeydew and sooty fungus on the leaves due to the secretion of honeydew by the insects.
- Presence of whiteflies flying around the plants.
- Molasses on the leaves and soil.
- Presence of sooty fungi on the leaves.
- Weakening of plants, reduced growth and yield.

- Use anti-insect nets to prevent whiteflies from entering the crops.
- Apply specific insecticides when necessary, using products that are effective against the different stages of insect development.
- Promote the diversity of natural enemies through the conservation of habitats and the introduction of predators and whitefly parasitoids.
- Implement integrated pest management practices, such as crop rotation and elimination of host weeds.
- Regularly monitor crops to detect the early presence of whiteflies and take preventive or control measures in a timely manner.
