How it works

How it works

Directions for use

Directions for use


Introduce Mirical at the beginning of the growing season and provide Entofood and/or Artefeed as food source, as the predatory bug population needs time to establish and develop. Mirical can also survive on plant saps, however absence of animal prey slows down the population build-up significantly.

Cardboard tray:

  • Open package carefully inside the greenhouse.
  • Distribute the content of one package over 10 introduction points by hanging 1 cardboard strip per plant and, at the end, shake out any remaining M. pygmaeus from the tray into the crop.
  • Hang the cardboard strips over the stalk of a fully-grown leaf at the top of the plant.
  • The Macrolophus will climb out of the cardboard strips and spread through the crop.


  • Sprinkle material on clean, dry rock wool slabs, in Diboxes or on leaves. Make sure the material is not disturbed for at least a few hours
  • Introduce in clusters of at least 50 predatory bugs
  • Create 6-10 distribution points per bottle
  • Spread material thinly (maximum 1 cm thick) to enable the predatory bugs to get out of the carrier material.


The dosage of Mirical depends on climate, crop and expected pest density and should always be adjusted to the particular situation. Start introduction preventively. Introduction rates typically range from 0.25-5 per m2/release. Releases should be repeated after 2 weeks. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.

Environmental conditions

Optimal temperatures for Mirical are above 20°C/68°F, lower temperatures slow down the development of Macrolophus pygmaeus significantly.

Combined use

Should be used in combination with whitefly parasitoids.
