¿QUIÉN LO CAUSA?
Saissetia oleae, commonly known as the sooty mealybug, is a species of scale insect that affects olive trees. These insects feed on plant sap, causing weakening and stress to the trees. Additionally, they produce a sticky substance called honeydew, which serves as a growth medium for the sooty mold fungus. Sooty mealybug reproduction can be sexual or asexual, and females can lay up to 500 eggs in a single season.

SÍNTOMAS
The disease that occurs in olive trees is characterized by the presence of honeydew on the branches and leaves, which gives rise to the formation of a layer of black fungus known as sooty mold. This affects the plant's photosynthesis, as the sooty layer blocks sunlight.
• Presence of honeydew on branches and leaves.
• Formation of a layer of soot on the molasses.
• Loss of vigor in the plant.
• Decrease in the quality and quantity of the olive harvest.
• Branches and leaves weakened and yellowed.
