WHO CAUSES IT?
The worm, scientifically known as Chrysodeixis chalcites, is a common pest that affects geranium and other garden plants. This insect belongs to the Noctuidae family and is characterized by its green color and voracious eating habit. It feeds on the young leaves of the geranium, leaving characteristic holes in them and causing significant damage to the plant if the infestation is severe.

SYMPTOMS
The disease caused by the worm in geranium manifests itself mainly as damage to the leaves. Symptoms include the presence of irregular holes in the leaves, as well as leaf wear and discoloration. Additionally, insect feces may be observed near affected areas and, in severe cases, the plant may show poor growth and an overall deteriorated appearance.

Recommendations
To prevent maggot infestation in geranium, it is recommended to perform regular plant inspections for signs of larvae or leaf damage. Additionally, organic mulch can be used around plants to discourage egg laying and promote the presence of natural predators of the worm. As for control, specific insecticides can be applied to control moth larvae, such as the geranium worm.
