The Potential Impacts of the Arrival of the Harlequin Ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), in Britain

Ecological Entomology, 2006
The harlequin ladybird, Harmonia axyridis, has recently arrived in Britain. This species has been introduced from Asia into many parts of the world for biological control purposes.

Comment on “Invasive Harlequin Ladybird Carries Biological Weapons Against Native Competitors” [PDF]

Science, 2013
We comment on the implications that Vilcinskas et al . (Reports, 17 May 2013, p. 862) attach to the finding that the exotic, invasive ladybird Harmonia axyridis carries microsporidia to which this species is insensitive but that is lethal to species that are native to the invaded areas.

Entomopathogenic Fungi Recorded From the Harlequin Ladybird, Harmonia axyridis

Journal of Invertebrate Pathology, 2009
Entomopathogenic fungi were recorded from field samples of the harlequin ladybird Harmonia axyridis, an invasive coccinellid that has recently arrived in Denmark. Larvae, pupae and adults were found to be infected by Isaria farinosa, Beauveria bassiana and species of Lecanicillium. This is the first record of entomopathogenic fungi infecting larvae and

Harmonia axyridis (harlequin ladybird).

2021
Abstract H. axyridis, a species of Asian origin, has been used as a biological control agent against aphids worldwide. The first releases were made in North America in 1916, but it was not until 1988 that the first individuals were found in the wild.

Does the non-native Harlequin ladybird disrupt the feeding behaviour of the native two-spot ladybird?

Bulletin of Entomological Research, 2021
AbstractSince its arrival in 2004, the non-native Harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae) has rapidly spread throughout Britain, and it is now the most common coccinellid in England. There have since been concerns about the detrimental effects it may have on native coccinellids because there is a strong correlation between the ...

Harlequin Ladybird Harmonia axyridis Pall. (Coleoptera, Coccinellidae) in Armenia

Russian Journal of Biological Invasions, 2017
Information on the first finding (one specimen) in Armenia of an invasive species of beetle, harlequin ladybird Harmonia axyridis, is presented. Invasion from Georgia as a result of self-expansion or unintentional delivery is presumed.

Potential diet regimens for laboratory rearing of the harlequin ladybird

BioControl, 2020
Harmonia axyridis Pallas (Coleoptera: Coccinellidae) is an invasive generalist predator, which has been used as a biological model to investigate several research questions and is also an effective biocontrol agent against agricultural pests. Its laboratory colonies are often maintained on natural prey that are costly, and thus alternative dietary ...

Cold tolerance of the harlequin ladybird Harmonia axyridis in Europe

Journal of Insect Physiology, 2010
As an essential aspect of its invasive character in Europe, this study examined the cold hardiness of the harlequin ladybird Harmonia axyridis. This was done for field-collected populations in Belgium overwintering either in an unheated indoor or an outdoor hibernaculum. The supercooling point, lower lethal temperature and lower lethal time at 0 and -5

The Harlequin ladybird continues to invade southeastern Europe

Biological Invasions, 2010
The ladybird Harmonia axyridis (Pallas) is considered one of the most serious invasive species around the globe. It has spread all over North America and Western Europe, while data from southeastern Europe, especially in the Mediterranean region, are scarce. In this study we present the first confirmed data of the spread of H.
