WHO CAUSES IT?
Aphids, belonging to different species of the Aphididae family, are small, soft insects that feed on plant sap. These pathogens reproduce both asexually, through parthenogenesis, and sexually. Parthenogenetic females can produce numerous live offspring without mating, allowing for rapid population expansion. During the life cycle of aphids, they can go through several generations of asexual reproduction before sexual males and females are produced. These sexual generations usually occur in response to environmental factors such as reduced host quality or seasonal changes. After mating, sexual females lay winter-hardy eggs, which hatch in spring and restart the cycle. Aphids can also develop wings in certain generations, allowing them to disperse to new plants.

SYMPTOMS
The infestation of aphids in the loquat causes a disease that manifests itself in various parts of the plant, mainly in leaves and tender shoots. Aphids suck the sap, weakening the plant and reducing its vigor. Additionally, they excrete a sugary substance called molasses, which favors the growth of black fungi known as sooty molds, affecting photosynthesis.
- Rolled and deformed leaves.
- Yellowing and premature leaf fall.
- Deformed buds and flowers.
- Presence of sticky honeydew on leaves and stems.
- Growth of sooty mold on molasses.
- Small and deformed fruits.
- Delayed growth and general weakening of the plant.

Recommendations
- Regularly monitor plants for early signs of infestation.
- Use yellow sticky traps to catch flying aphids.
- Introduce and encourage natural enemies such as ladybugs, lacewings and parasitoid wasps.
- Apply horticultural oils or insecticidal soaps to suffocate and eliminate aphids.
- Prune the infested parts of the plant and destroy them properly.
- Maintain good garden hygiene, eliminating plant debris that may harbor pests.
- Avoid excess nitrogen fertilization, which can promote the growth of aphids.
- Implement physical barriers such as fine mesh to prevent aphids from accessing plants.
- Alternate the use of insecticides with different modes of action to prevent resistance.
- Apply preventive treatments in times of greatest risk, such as spring and autumn.
