Sphaerophoria rueppellii: hoverfly larvae against aphids

What is Sphaerophoria rueppellii?

  • Endemic hoverfly
  • Indigenous to Europe
  • Biological control agent against aphids
  • Sphaerophoria larvae also eat whitefly, thrips and spider mite
  • Adult hoverflies are harmless. They feed on pollen and nectar
  • The larvae are essential for effective control
  • Sufficient daylight is important for good activity. The hoverflies are not as active in autumn
  • For the commercial introduction of Sphaerophoria-System, Biobest worked together with BioNostrum, a spin-off company of the University of Alicante

What are the benefits of Spaerophoria ruepelli?

  • The hoverflies are active in a wide range of temperatures (10°C – 40°C); but achieve the best results between 25°C and 35°C
  • You can combine Sphaerophoria rueppellii with aphid parasitoids. Hoverfly larvae only eat the non-parasitic aphids. By using both, you reduce the number of aphids in your crops even more drastically
  • Sphaerophoria-System can be introduced easily and does not need additional flowering plants

How does it control pests?

  • Females can lay up to 400 eggs a day
  • Adult females search for aphid infestations to lay their whitish grey oval-shaped eggs
  • They prefer to lay their eggs in large colonies to avoid a lack of prey
  • In 9 days and at 25°C, the green larvae that hatch from the eggs can devour up to 200 aphids before pupating
