How to use

Rophoria is supplied as 100 pupae, from which adult Sphaerophoria rueppellii hoverflies emerge.

Introduce the pupae into the treatment area according to the product-specific instructions. After emergence, the adult hoverflies disperse through the crop and search for aphid colonies where they can lay their eggs.

The resulting larvae then feed directly on aphids within the colonies.

Monitor aphid populations and hoverfly activity following introduction and follow the product-specific guidance for application rates, introduction frequency and suitable crop conditions.

Tech Comments Combined use: For effective control of aphids combine with other predators and/or parasitoids.
Control The larval stage of Sphaerophoria rueppellii consume aphids, with the adult hoverflies feeding on pollen and nectar in the environment making flowering crops much more favourable for this species to establish in, if no flowers are present in the area look to apply alternative predators instead, such as the Adalia or Chrysoperla species. 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.
