How it works

How it works

Mode of action

Adult hoverflies emerge from the pupae and deposit their eggs in the aphid colonies. The young larvae start feeding on the aphids.

Visual effect

Aphids are consumed entirely, only skins remain. Dark excrements (meconium) on the leaves is an indicator of hoverfly larvae activity.

Do not open the box until you arrive at the release point. Carefully open the perforated lid of the carboard box. Hang the open box vertically on the plants, preferably close to flowers. Protect from direct sunlight or rain.


The dosage of Rophoria depends on climate, crop and aphid density and should always be adjusted to the particular situation. Start introduction preventatively or as soon as the first aphids are detected in the crop. Introduction rates typically range from 200-600 pupae per ha/release. Releases should be repeated a number of times. Consult a Koppert advisor or recognized distributor for advice on the best strategy for your situation."

Environmental conditions

  • Rophoria is most effective between 20 and 30°C.
  • High humidity is favourable for larval development and hatching of pupae.
  • Adult hoverflies feed on pollen and nectar. Ensure flowering plants are present for optimal establishment.

Combined use

For effective control of aphids combine with other predators and/or parasitoids.
