Harmonia axyridis: a threat to Brazilian Coccinellidae? Harmonia axyridis: uma ameaça aos Coccinellidae brasileiros? [PDF]

open access: goldRevista Brasileira de Entomologia, 2009
Harmonia axyridis (Pallas) (Coleoptera, Coccinellidae) is a polyphagous Asian species, well-known as a classical biological control agent of aphids around the world, introduced probably accidentally in Brazil, sampled for the first time in 2002. It is an

Double Infections of the Invasive Ladybird Harmonia axyridis [PDF]

open access: yesFrontiers in Ecology and Evolution, 2022
The dramatic spread of invasive alien species over the past century is considered to be an important threat to ecosystems worldwide. The harlequin ladybird, Harmonia axyridis, from eastern Asia, is considered to be one of the most invasive species ...

Effects of conspecific and heterospecific larval tracks on the oviposition behaviour of the predatory ladybird, Harmonia axyridis (Coleoptera: Coccinellidae) [PDF]

open access: goldEuropean Journal of Entomology, 2000
The effect of the oviposition deterring pheromone (ODP) in the larval tracks of conspecific and heterospecific ladybirds on oviposition in Harmonia axyridis Pallas was studied in semi natural conditions. Gravid females of H.

The chemical ecology of Harmonia axyridis [PDF]

open access: greenBioControl, 2011
We review the chemical ecology of the ladybird beetle Harmonia axyridis from the perspective of its invasiveness and the deleterious effects it exerts in the regions it has colonised. We outline the nature and quantification of its chemical defence, and discuss the protection this provides against natural enemies, particularly intraguild predators.

Inbreeding Depression Is Purged in the Invasive Insect Harmonia axyridis [PDF]

open access: bronzeCurrent Biology, 2011
Bottlenecks in population size reduce genetic diversity and increase inbreeding, which can lead to inbreeding depression. It is thus puzzling how introduced species, which typically pass through bottlenecks, become such successful invaders. However, under certain theoretical conditions, bottlenecks of intermediate size can actually purge the alleles ...
