DESCRIPTION
WHO CAUSES IT?
Bemisia tabaci, commonly known as whitefly, is a small insect approximately 1-2 mm in length. Adult females lay their eggs on the underside of leaves, preferring areas with a high density of young, tender leaves. Each female can lay between 100 and 300 eggs during her lifetime. The eggs hatch into nymphs that go through four instars before becoming adults. The nymphs attach to leaves and feed on plant sap, injecting toxic saliva that causes damage to plant tissues. Adults emerge from the pupae and begin to reproduce rapidly, especially in warm, humid conditions. Bemisia tabaci has a high reproductive capacity and a rapid development rate, allowing it to establish and proliferate quickly in crops.
SYMPTOMS
Whitefly produces a disease in plants that manifests itself through various symptoms that significantly affect the health and productivity of plants.
- Yellowing of leaves.
- Development of sooty mold on the leaves due to the secretion of honeydew.
- Reduction in plant growth and vigor.
- Withering and premature leaf fall.
- Deformation of shoots and new leaves.
- Appearance of chlorotic Taches on the leaves.
- Decrease in fruit production.
- Transmission of phytopathogenic viruses that aggravate the condition of the plant.

- Carry out regular monitoring to detect the presence of whiteflies in crops.
- Implement physical barriers such as anti-insect meshes in greenhouses and open fields.
- Introduce natural enemies such as parasitoids and specific whitefly predators.
- Apply potassium soap or mineral oils to reduce the population of nymphs and adults.
- Maintain an adequate crop rotation to interrupt the life cycle of the pathogen.
- Use yellow chromatic traps to attract and capture adults.
- Avoid excessive use of nitrogen fertilizers that promote the growth of tender tissues.
- Implement chemical treatments with specific insecticides, following the recommendations for integrated pest management.
- Promote crop diversity to reduce the susceptibility of the plantation to infestation.
