Invasive alien predators are a serious threat to biodiversity worldwide
The authors describe a method developed to assess which European ladybird species are most at risk following the invasion of H. axyridis. The 3 components of the risk assessment are:
- the likelihood that the assessed native species encounters H. axyridis in the field
- the hazard of competition for food
- the IGP hazard
