WHO CAUSES IT?
Spodoptera exigua, commonly known as armyworm or green donut, is a lepidopteran pest belonging to the family Noctuidae. Adults are medium-sized moths with grayish-brown forewings and zigzag markings. Females deposit their eggs in masses on the leaves of host plants. Each egg mass contains between 50 and 300 eggs, and each female can lay several hundred over her lifetime. The eggs hatch in a few days, releasing larvae that pass through five to six larval instars, during which they feed intensively on the leaves, stems and fruits of the plants. Mature larvae burrow into the soil to pupate. The pupal stage lasts approximately two weeks, after which the adult emerges. This cycle can be completed in one month under optimal conditions, allowing multiple generations per year in warm climates.

SYMPTOMS
In pepper, Spodoptera exigua causes significant damage due to its ability to feed voraciously on leaves and fruits. This damage reduces photosynthesis and weakens the plant, affecting both growth and fruit production. The presence of larval excrement and the disfigurement of the fruits also decrease the commercial value of the crop.
Irregular holes in the leaves
Severe defoliation
Damage to shoots and stems
Presence of larvae and excrement on the plant
Pierced and disfigured fruits
Reduction in fruit production
