WHO CAUSES IT?
The pathogens Empoasca decipiens Paoli, Empoasca solani Curtis, Asymmetrasca decedens Paoli and Jacobiasca lybica are insects commonly known as leafhoppers, leafhoppers or leafhoppers. These insects go through several stages during their development. Adults are small, approximately 3 mm in length, and have varied colors ranging from green to brown. Females deposit their eggs within plant tissues, mainly in the leaves. These eggs hatch and release nymphs that go through five instars before becoming adults. During these stages, nymphs and adults feed on the phloem of plants, inserting their mouthparts into leaves to extract sap. This feeding process not only weakens the plant, but can also transmit phytopathological diseases and cause direct damage from the toxins they inject. The presence of leafhoppers is common in hot, dry climates, where they can complete multiple generations per year, thus increasing their impact on crops.

SYMPTOMS
In peach, peach or nectarine, leafhopper infection produces several symptoms that affect the general health of the plant and the quality of the fruits. The feeding activity of these insects causes physiological stress in the plant, which results in a reduction in photosynthesis and growth. The leaves show symptoms of yellowing and mottling, which can lead to premature defoliation. Young shoots and fruits are also affected, showing uneven development and deformations.
- Yellowing and mottling of leaves
- Premature defoliation
- Uneven development of shoots
- Deformations in the fruits
- Reduction in photosynthesis
- General physiological stress in the plant
- Loss of vigor in affected trees
