Abstract

The Harlequin ladybird (Harmonia axyridis) is a biological control agent ‘gone wrong’ in that as well as being an effective predator of aphids, it will also feed on native coccinellid species in the UK, and is likely to out compete many native coccinellids, primarily through resource competition and intra-guild predation. It has already invaded the UK and its potential spread under current and future climates is predicted using CLIMEX models based on its response to climatic stress factors such as temperature, rainfall and induction of diapause. By 2050, whether using low or medium emissions climate change scenarios, H. axyridis has the potential to spread throughout most of Europe and the UK. Factors that
can affect its establishment are discussed.
