What is Ervi-System?

  • The biological control agent Aphidius ervi
  • Most frequently used parasitic wasp to control large aphids
  • Efficient against large aphid species such as the potato aphid Macrosiphum euphorbiae and the buttercup aphid Aulacorthum solani
 What are the benefits of Ervi-System?
  • Very good search behaviour that allows them to detect and parasitize incipient aphid hot spots at low prey density
  • Can distinguish parasitized from non-parasitized aphids
  • Develops and spreads fast in the crop
  • Adapted to low temperatures 
How does biological control with Ervi-System work?
  • Females lay hundreds of eggs during the first 4 days of their adult life
  • The parasitic wasps detect alarm signals from an affected plant and the smell of honeydew secreted by the host. This allows them to locate aphid hot spots from a long distance
  • They can parasitize hundreds of aphids
  • The parasitic wasps parasitize both adults and nymphs
  • Parasitized aphids change into golden brown mummies
  • Parasitic wasps can cause a panic reaction, due to which the aphids fall onto the ground and die
