The First Record of Aphidius ervi Haliday in Slovenia [PDF]
Acta Agriculturae Slovenica, 2009 In 2008, a lucerne aphid parasitoid Aphidius ervi Haliday was first recorded in Slovenia. This oligophagous parasitoid is used as biological control agent against bigger aphid species. By sampling aphid mummies on different locations in Slovenia in 2008,

Effect of Innate Preferences, Conditioning and Adult Experience on the Attraction of Aphidius ervi (Hymenoptera: Braconidae) Toward Plant Volatiles [PDF]
European Journal of Entomology, 2002 The aphid parasitoid Aphidius ervi was collected and subsequently reared on Sitobion avenae on wheat or Acyrthosiphon pisum on alfalfa. Parasitoids from both origins were exposed in an olfactometer to alfalfa or wheat volatiles after plant experience ...

Non-consumptive effects stabilize herbivore control over multiple generations.
PLoS ONE, 2020 Understanding the factors that influence predator-prey dynamics requires an investigation of oscillations in predator and prey population sizes over time. However, empirical studies are often performed over one or fewer predator generations.
