Introductions of the harlequin ladybird Harmonia axyridis into Belgium for aphid biological control have been followed by declines in native aphid natural enemies. We first examined, in laboratory and field conditions, the impact of larval mobility of either H. axyridis or Episyrphus balteatus, the most abundant native hoverfly in central Europe, on aphid suppression. The hoverfly larvae consumed more aphids (Megoura viciae) in a short term, whereas the ladybird ones were more efficient in a long term. We second investigated the intraguild interactions between H. axyridis and E. balteatus larvae and adults. In larva pairings between the two species in laboratory microcosms containing aphid (M. viciae) infested broad bean (Vicia faba) plants, H. axyridis had an intraguild predation (IGP) advantage over the hoverfly. When conspecific larvae were paired together on aphid‐infested plants, no cannibalism between them was detected. The presence of either H. axyridis or E. balteatus larvae on aphid‐infested plants negatively influenced the ovipositional behaviour of H. axyridis and E. balteatus females; lower numbers of laid eggs were recorded compared to control treatment. Moreover, eggs laid by E. balteatus females were also dropped as victims of predation mainly by H. axyridis larvae. Our results suggest that while the exotic ladybird was more efficient in aphid biological control, larvae and eggs of the native hoverfly species face increased IGP by H. axyridis, which would contribute, as a consequence, to the decline in E. balteatus population following invasion.

“…Although H. axyridis was considered an efficient predator of various species of aphids (Koch, 2005), studies should be conducted to observe their influence on the food chain (Zawadneak, 2006). It is an exotic insect that was first recorded in Brazil in 2002 (Almeida and Silva, 2002) and is predominant in many areas of study in Paraná (Almeida and Silva, 2002;Zawadneak, 2006). Koch (2005) cited coccinellid species that can feed on ripe fruit in Europe, such as peaches, contaminating them with their droppings.…”

“…Koch (2005) cited coccinellid species that can feed on ripe fruit in Europe, such as peaches, contaminating them with their droppings. In North America, H. axyridis has been designated pest status (Koch, 2005), since it has the habit of invading houses in the colder seasons of the year, seeking shelter and food (Almeida and Silva, 2002).…”
