Leaf miners – natural control for healthy plants
Leaf miners are dreaded pests in gardens and greenhouses. Their larvae cause typical feeding tunnels in leaves and significantly weaken plant growth. Here's how to identify and control leaf miners, and prevent future infestations using natural remedies.
An overview of the pest
Leaf miners (Agromyzidae) lay their eggs on leaves. After hatching, the larvae bore into the leaf tissue, leaving unsightly tunnels that significantly impair plant growth.
Life cycle of leaf miners
After a few days, the larvae hatch and leave the typical feeding tunnels in the leaf. After two to three weeks, they pupate in the soil and develop into adult flies. Early intervention is crucial to breaking the cycle.
How to recognize an infestation
- Typical feeding tunnels as white or yellow lines on the leaves
- Deformed or yellowed leaves
- Weakening of plant growth
Natural methods to combat
- Ichneumon wasps (Dacnusa sibirica TELENGA): These beneficial insects parasitize the larvae and thus stop the infestation effectively and sustainably.
- Mechanical removal: Remove infected leaves regularly and dispose of them safely.
- Thorough cleaning: Keep plant areas clean to contain infestation.
Preventive measures
- Regular inspection of plants
- Strengthening plants through balanced care and nutrient supply
- Early release of parasitic wasps
- Removal and safe disposal of infected leaves
