Bridgehead effect in the worldwide invasion of the biocontrol harlequin ladybird. [PDF]
PLoS ONE, 2010 Recent studies of the routes of worldwide introductions of alien organisms suggest that many widespread invasions could have stemmed not from the native range, but from a particularly successful invasive population, which serves as the source of ...

Transgenerational Effects of a Neonicotinoid and a Novel Sulfoximine Insecticide on the Harlequin Ladybird [PDF]
Insects, 2021 The harlequin ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), is a generalist predator and an effective biocontrol agent of various insect pests that has been exploited for the control of aphid pests in the greenhouse and field.

Global patterns of genomic and phenotypic variation in the invasive harlequin ladybird [PDF]
BMC Biology, 2023 Background The harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae), native to Asia, has been introduced to other major continents where it has caused serious negative impacts on local biodiversity.

The invasion history, distribution and colour pattern forms of the harlequin ladybird beetle Harmonia axyridis (Pall.) (Coleoptera, Coccinellidae) in Slovakia, Central Europe [PDF]
ZooKeys, 2014 The harlequin ladybird beetle Harmonia axyridis (Coleoptera, Coccinellidae) has invaded and established in Slovakia. Following unintentional introduction in 2008, the spread of the alien coccinellid was very fast.

Exotic predators are not better biocontrol agents: the harlequin ladybird is not the most voracious in Mexico [PDF]
PeerJ, 2021 The use of exotic species for pest biocontrol has been a common pathway for introduction and dispersal of invasive species that may have undesired outcomes.

The genome sequence of the harlequin ladybird, Harmonia axyridis (Pallas, 1773) [version 3; peer review: 1 approved, 2 approved with reservations, 1 not approved] [PDF]
Wellcome Open Research, 2021 We present a genome assembly from an individual female Harmonia axyridis (the harlequin ladybird; Arthropoda; Insecta; Coleoptera; Coccinellidae). The genome sequence is 426 megabases in span.

From effective biocontrol agent to successful invader: the harlequin ladybird (Harmonia axyridis) as an example of good ideas that could go wrong [PDF]
PeerJ, 2017 The use of biological control agents to control pests is an alternative to pesticides and a tool to manage invasive alien species. However, biocontrol agents can themselves become invasive species under certain conditions.

Antennal Transcriptome Analysis and Identification of Candidate Chemosensory Genes of the Harlequin Ladybird Beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) [PDF]
Insects, 2021 In predatory ladybirds (Coleoptera: Coccinellidae), antennae are important for chemosensory reception used during food and mate location, and for finding a suitable oviposition habitat.

Effect of a Marking Pheromone and Population Density on Ladybird Larval Development and Adult Body Mass [PDF]
InsectsFemales of predaceous ladybirds use sensing chemicals in larval tracks as an oviposition-deterring pheromone to avoid cannibalism of eggs. We hypothesized that larvae would also respond to the presence of conspecific tracks by slowing their developmental
