Practical biological control, IPM and environmental pest-management knowledge.

Capsid Bugs

Overview

Capsid bugs are sap-feeding true bugs that can damage young growth, flowers and developing fruit.

They are important in:


Symptoms

Typical symptoms include:

  • distorted young leaves
  • damaged growing points
  • flower bud damage
  • misshapen fruit
  • small feeding marks
  • uneven fruit development

Risk conditions

Condition Risk
Soft young growth High
Flowering crops High
Weedy margins Moderate
Warm spring weather Moderate–High

Monitoring

Inspect:

  • shoot tips
  • flower buds
  • young leaves
  • field/tunnel edges
  • developing fruit

IPM approach

Useful strategies:

  • inspect young growth early
  • monitor edges and hotspots
  • reduce unmanaged weed reservoirs where appropriate
  • protect beneficial insects where possible
  • respond before fruit distortion becomes widespread

Key message

Capsid damage often appears as distortion, so early shoot and flower inspections are important.
