DESCRIPTION
WHO CAUSES IT?
Myzus persicae, Aphis gossypii, Macrosiphum euphorbiae and Aulacorthum solani are species of aphids that affect pepper. These insects have a complex life cycle, with several generations per year. They begin as eggs that overwinter attached to the plant or in the soil. In spring, the eggs hatch into nymphs that quickly mature into adults. Adults can reproduce asexually through parthenogenesis, allowing rapid population increase. Adult females give birth to live nymphs, which do not go through an egg phase, and these nymphs develop into adults within days. Some adults develop wings and disperse to new host plants, expanding the infestation. In autumn, aphids produce sexual males and females that mate and lay eggs, completing the annual cycle.
SYMPTOMS
The aphid causes a disease in pepper that manifests itself with several distinctive symptoms. These insects suck the sap from plants, weakening them and reducing their growth. The infestation causes yellow Taches and deformations on the leaves, as well as the production of honeydew, a sticky substance that encourages the growth of sooty fungi. Additionally, aphids can transmit plant viruses, increasing damage to crops. The leaves curl and wrinkle, and the plant may appear generally wilted.

Use aphid-resistant pepper varieties.
Implement a crop rotation program to avoid the accumulation of aphids in the soil.
Maintain an adequate distance between plants to improve air circulation and reduce humidity.
Introduce natural predators of aphids, such as ladybugs and lacewings, to control the population biologically.
Apply horticultural oils and insecticidal soaps as a preventive and control treatment.
Carry out regular monitoring of crops to detect the presence of aphids early and act quickly.
Avoid excessive use of nitrogen fertilizers, as they promote the growth of tender tissues susceptible to aphids.
Use yellow sticky traps to monitor and reduce the aphid population by catching flying adults.
