American Serpentine Leafminer

Overview

American serpentine leafminer is a leafmining fly associated with protected crops, ornamentals and vegetables.

It creates narrow winding mines in leaves and can reduce crop quality, especially where leaves are part of the marketable crop.

Symptoms

  • narrow serpentine mines
  • pale feeding trails
  • dark frass lines inside mines
  • reduced leaf quality
  • adult fly activity around foliage

Crop relevance

Relevant in:

  • ornamentals
  • protected vegetables
  • leafy crops
  • herbs
  • nursery systems

IPM relevance

Management focuses on:

  • early detection
  • removal of heavily mined leaves
  • parasitoid conservation
  • weed host management
  • avoiding disruptive sprays

Biological control relevance

Useful biological control may include:

Additional IPM notes

American serpentine leafminer causes narrow winding mines in leaves.

It can affect protected crops, ornamentals and leafy crops.

Mines reduce leaf quality and may reduce photosynthetic area under heavy pressure.

Monitoring should focus on new mines, adult activity and crop batches with previous history.
