Pear Sucker

Overview

Pear sucker is a major pest of pear orchards.

It feeds on sap and produces honeydew, which can lead to: - sticky leaves - sooty mould - reduced fruit quality - weakened growth


Main host crop


Identification

Look for:

  • small jumping insects
  • nymphs on young shoots
  • honeydew
  • sticky foliage
  • sooty mould
  • distorted or weakened shoots

Risk conditions

Condition Risk
Warm sheltered orchards High
Dense canopy High
Soft growth Moderate–High
Low natural enemy activity High

Monitoring

Inspect:

  • young shoots
  • leaf undersides
  • fruit clusters
  • sticky honeydew zones

IPM approach

Useful strategies:

  • maintain open canopy
  • avoid excessive soft growth
  • preserve natural enemies
  • monitor early spring growth
  • reduce stress

Key message

Pear sucker is best managed by early monitoring, canopy airflow and preservation of natural enemies.
