DESCRIPTION

Pathogen description

The cottony mealybug is a sap-sucking insect belonging to the Pseudococcidae family. These insects are known for their cottony appearance, as they are covered in a white waxy substance. They feed on plant sap, weakening their health and causing direct and indirect damage, such as the secretion of honeydew that can attract the appearance of black mold fungi.

Disease description

In citrus, the cottony mealybug can cause yellowing of the leaves, general weakening of the plant and a decrease in fruit production and quality. The honeydew secreted by these insects can promote the growth of sooty mold fungi, which stain the leaves and fruits, negatively affecting photosynthesis.

• Yellowing of the leaves.
• General weakening of the plant.
• Decrease in the production and quality of the fruits.
• Presence of sticky honeydew on the leaves and fruits.
• Appearance of sooty fungus.

Preventive treatments

• Regular inspection of plants to detect early infestations.
• Biological control through the introduction of natural predators, such as ladybugs and parasitoid wasps.
• Application of specific insecticides to control populations.
• Prune and eliminate the most affected parts of the plant.
• Clean the honeydew from the leaves with soapy water to prevent the proliferation of fungi.
