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.
