Diglyphus isaea

Diglyphus isaea

Type

Parasitoid wasp

Target pests

Best use

Key tool for leafminer control in protected crops (including tomatoes).

Notes

Works best with early detection and regular releases.

Best deployment strategy

  • Introduce as soon as leafminer mines are detected.
  • Target known hot-spots; repeat until new mining activity declines.
  • Combine with hygiene and leaf removal where appropriate to reduce pest reservoirs.

Compatibility notes

  • Works well with: hygiene/cultural control and leaf removal (where appropriate) to reduce leafminer reservoirs.
  • Avoid: broad-spectrum insecticides that disrupt parasitoid activity.

Environmental preferences

  • Performs best in stable greenhouse conditions where leafminer is present.
  • Very cool conditions slow parasitoid activity and development.
