WHO CAUSES IT?
Mealybugs are small insects belonging to the Coccoidea family, which includes several species with different habits and characteristics. Adult females deposit eggs en masse on the surface of plants, protected by a waxy covering. The eggs hatch into mobile nymphs, called “crawlers,” which disperse in search of suitable feeding sites. These nymphs attach themselves to the plant and begin to suck the sap, developing through several nymphal stages until they become adults. Female scale insects are usually sessile, while the less common males undergo complete metamorphosis and become winged insects capable of flying and searching for females to mate with. The females continue to produce eggs, thus completing the life cycle that can repeat several times a year, depending on environmental conditions.

SYMPTOMS
Mealybug infestation causes a series of problems in plants, compromising their vigor and general health. Mealybugs suck the sap from plants, weakening them and affecting their growth. This damage can manifest itself in various ways, depending on the intensity of the infestation and the species of mealybug involved. Common symptoms of infestation include:
- Yellowing and premature leaf fall.
- Presence of yellow or chlorotic Taches on the leaves.
- Deformation of shoots and fruits.
- Appearance of a sticky substance called honeydew on leaves and stems.
- Development of sooty mold (black mold) on honeydew.
- Reduction in the general growth of the plant.
- Regressive death of severely affected branches and shoots.
