How to spot it
The pear leafhopper (Cacopsylla pyri) is a small jumping insect that feeds on pear trees and exudes sticky honeydew.
The honeydew coats leaves, flowers, and fruits and often forms black sooty mold that hampers photosynthesis.
You notice infestation by rolled, glossy sticky leaves, puckered spots on the fruits, and the tiny, hopping insects on the underside of the leaves.
Prevention
Choose robust, low‑susceptibility pear varieties and plant trees with enough spacing so the canopy stays airy.
A light canopy pruning in winter removes hiding places for the pest and improves airflow.
Encourage beneficial insects such as flower flies, predatory bugs, and ladybirds by planting flowering strips and insect hotels nearby; they keep the population naturally in check.
Avoid excessive nitrogen fertilization, as tender shoots especially attract the leafhopper, and hand‑pick infected shoot tips in spring.
