Native ladybird decline caused by the invasive harlequin ladybird Harmonia axyridis : evidence from a long‐term field study

Insect Conservation and Diversity, 2017
Abstract Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) is regarded as an invasive non‐native species in Europe, where it has been spreading rapidly since the early years of the 21st century.

Harmonia axyridis (Boyer de Fonscolombe) (Hemiptera: Coccoidea) as a potential biological control agent of the invasive soft scale, Sphaerolecanium prunastri (Boyer de Fonscolombe) (Hemiptera: Coccoidea) in native wild apricot forests

Egyptian Journal of Biological Pest Control
Background The globose scale (GS), Sphaerolecanium prunastri (Boyer de Fonscolombe) (Hemiptera: Coccoidea), has invaded wild apricot forests in their native range in Central Eurasia threatening the ancestral germplasm resource.

Effects of so-called "environmentally friendly" agrochemicals on the harlequin ladybird Harmonia axyridis (Coleoptera: Coccinel[l]idae)

European Journal of Entomology, 2019
A variety of plant protection products and other agrochemicals are used in agro-ecosystems. Products approved for integrated pest management (IPM) or organic farming should have minimal negative side effects on beneficial insects.

Responses of avian predators to the polymorphic harlequin ladybird (Harmonia axyridis)

Ecological Entomology, Volume 49, Issue 3, Page 357-367, June 2024.
Harlequin ladybird shows high colour polymorphism with particular colour forms differing substantially in their abundance in nature in Central Europe, where this species acts as invasive. We experimentally showed that two species of passerine birds substantially differ in their attitude to this ladybird species, very likely due to their diet ...

The effect of the coccinellid Harmonia axyridis (Coleoptera: Coccinellidae) on transmission of the fungal pathogen Pandora neoaphidis (Entomophthorales: Entomophthoraceae)

European Journal of Entomology, 2011
The coccinellid Harmonia axyridis is a recent arrival in the UK and is an intraguild predator of the entomopathogenic fungus Pandora neoaphidis. Harmonia axyridis entirely consumes P. neoaphidis-sporulating cadavers and this may have a negative effect on
