Entomopathogenic fungi recorded from the harlequin ladybird, Harmonia axyridis
Journal of Invertebrate Pathology, 2009Entomopathogenic 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

Invasive Harlequin Ladybird Carries Biological Weapons Against Native Competitors
Science, 2013Surprise Attack Humans conduct the largest ecological experiment ever by continually moving species between continents. For example, the harlequin ladybird beetle, native to Asia, has become highly invasive in many regions after being introduced for biological control, but we do not understand why this species ...

The Harlequin ladybird continues to invade southeastern Europe
Biological Invasions, 2010The 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.

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 ...

Harmonia axyridis (harlequin ladybird).
2021Abstract 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.

Potential diet regimens for laboratory rearing of the harlequin ladybird
BioControl, 2020Harmonia 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 ...

Can contamination by major systemic insecticides affect the voracity of the harlequin ladybird?
Chemosphere, 2020Systemic neurotoxic insecticides are widely used to control aphid pests worldwide and their potential non-target effects on aphid predators are often unknown. Behavioral responses linked to biological control services are crucial when assessing the compatibility of chemicals with biocontrol organisms.
