DESCRIPTION
WHO CAUSES IT?
Aphis gossypii and Myzus persicae are two species of aphids that affect celery. Both aphids have a similar morphology: small, soft, oval-shaped bodies that can vary in color from light green to yellow, black or even pink. Aphis gossypii, known as the cotton aphid, is polyphagous and attacks various plants, while Myzus persicae, the peach aphid, is equally versatile. Parthenogenetic females produce live offspring without the need for males, allowing rapid proliferation. Under favorable conditions, a single female can produce dozens of offspring in a few days. Aphids go through several nymphal stages before becoming winged or wingless (wingless) adults. The winged adults can disperse to new plants, facilitating infestation in large crop areas.
SYMPTOMS
In celery, infestation by Aphis gossypii and Myzus persicae can cause significant damage that affects the quality and yield of the crop. These aphids feed by sucking sap from leaves and tender stems, weakening the plant and reducing its growth. In addition, they are vectors of various phytopathogenic viruses.
- Rolled and deformed leaves.
- Yellow and chlorotic Taches on the leaves.
- Secretion of molasses, which favors the growth of sooty fungus.
- Decrease in plant vigor and growth.
- Transmission of viruses that can cause mosaics and deformations.
- Presence of visible colonies of aphids on the leaves and stems.

EFFECTIVE PRODUCTS TO ELIMINATE THIS DISEASE
- Regularly monitor crops to detect the early presence of aphids.
- Encourage the presence of natural enemies such as ladybugs, lacewings and parasitoid wasps.
- Avoid excessive use of nitrogen fertilizers, which can promote the growth of aphid populations.
- Implement crop rotation to break the life cycle of aphids.
- Use yellow sticky traps to monitor and control winged aphid populations.
- Apply insecticidal soap or horticultural oils to affected areas to control infestations.
- Consider using trap crops that attract aphids away from celery.
- Carry out treatments with specific insecticides, respecting the action thresholds and avoiding resistance.
