Leaf miners (Lyriomyza spp.).
How it works
Mode of action
Adult female parasitic wasps of Diglyphus isaea kill second and third instar leaf miner larvae in the mine and lay their eggs next to them. The eggs develop into parasitic wasps inside the mine (but outside the leaf miner), using the dead larvae as food. Adult females also kill young leaf miner larvae by using them as a food source. This is known as host feeding.
The presence of Diglyphus isaea in the crop is signalled by short mines that contain dead leaf miner larvae. Older larvae and pupae are visible through the leaf.

Directions for use
- Release parasitic wasps between the leaves of the crop in the morning or in the evening
The dosage of Miglyphus depends on climate, crop and leaf miner density and should always be adjusted to the particular situation. Start introduction as soon as the first mines are visible in the crop. Introduction rates typically range from 0.25-3 per m2/release. Releases should be repeated at least 3 times at weekly intervals or until control is achieved. At low temperatures (
Diglyphus isaea is most effective at temperatures between 15°C and 25°C (59 and 77°F).
