WHO CAUSES IT?
Caraviella aegopodii, Myzus persicae and Aphis spp. They are phytophagous insects commonly known as aphids. These small winged or wingless insects feed by sucking plant sap. Their life cycle includes several stages, beginning with laying eggs on the leaves and stems of host plants. Nymphs emerge from the eggs and, through successive molts, become adults in approximately one week under favorable conditions. Adults can reproduce both sexually and asexually, with some species capable of producing viviparous clones. Aphids can form large colonies in a short time, especially in warm, humid weather conditions.

SYMPTOMS
Aphid infestation in carrot can cause significant disease, negatively impacting plant health and performance. Aphids suck the sap, weakening the plant and reducing its growth. Additionally, these insects are vectors for viruses that can cause additional diseases. Affected plants show visible signs of stress and deterioration.
- Curling and deformation of the leaves.
- Yellowing or chlorosis.
- Presence of honeydew on the leaves, which attracts sooty fungi.
- Reduction in plant growth and vigor.
- Transmission of viruses, resulting in mosaics and other viral diseases.

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.
