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.
