Chrysanthemum Leafminer
Overview
Chrysanthemum leafminer is relevant in ornamental production where leaf mining damage reduces plant quality and marketability.
Protected ornamental systems can support repeated generations if populations are not detected early.
Symptoms
- serpentine mines
- pale leaf trails
- visible frass lines
- reduced ornamental quality
- adult fly activity
Crop relevance
Important in:
- chrysanthemums
- ornamentals
- nursery stock
- protected propagation
IPM relevance
Management should focus on:
- regular scouting
- removing heavily mined leaves
- maintaining parasitoid activity
- checking incoming plants
- avoiding broad-spectrum disruption

Additional IPM notes
Chrysanthemum leafminer reduces visual crop quality through visible mining damage.
Protected crops and continuous production systems are higher risk.
Monitoring should focus on new mines, older mined leaves and adult activity on sticky traps.
Preserving parasitoids and removing heavily mined leaves can help slow population build-up.
