Behavioral and Immunological Features Promoting the Invasive Performance of the Harlequin Ladybird Harmonia axyridis [PDF]

open access: yesFrontiers in Ecology and Evolution, 2017
The harlequin ladybird Harmonia axyridis is now established as a model to test hypotheses explaining why some species become successfully invasive, while others, even closely related ones, do not.

Developmental correspondence of juvenile stages across the locust, harlequin ladybird, and diamondback moth [PDF]

open access: yesiScience
Summary: Insect metamorphosis is a captivating aspect of animal research. To address the controversy regarding the developmental correspondence between hemimetabolous and holometabolous insects, we utilized non-destructive micro-computed tomography (CT ...

The Genomic Basis of Color Pattern Polymorphism in the Harlequin Ladybird [PDF]

open access: yesCurrent Biology, 2018
Many animal species are comprised of discrete phenotypic forms. Understanding the genetic mechanisms generating and maintaining such phenotypic variation within species is essential to comprehending morphological diversity. A common and conspicuous example of discrete phenotypic variation in natural populations of insects is the ...

First record of the harlequin ladybird, Harmonia axyridis (Coleoptera: Coccinellidae) in the Caucasus [PDF]

open access: yesEuropean Journal of Entomology, 2013
This is the first record of the harlequin ladybird Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) occurring in the Caucasus (Sochi region of Krasnodar territory, Russia). All the adults collected in the field there and reared from collected eggs,

Antennal Transcriptome Analysis and Identification of Candidate Chemosensory Genes of the Harlequin Ladybird Beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) [PDF]

open access: yesInsects, 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.

Distribution and identification of the harlequin ladybird Harmonia axyridis

open access: yes, 2006
Britain has a new ladybird species—and it is distinctly unwelcome. The Harlequin Ladybird Harmonia axyridis arrived from mainland Europe in 2004 and has rapidly established itself over large parts of south-east England.

Invasive harlequin ladybird carries biological weapons against native competitors

open access: yesScience, 2022
S.862-863Invasive species that proliferate after colonizing new habitats have a negative environmental and economic impact. The reason why some species become successful invaders, whereas others, even closely related species, remain noninvasive is often ...

Decline in native ladybirds in response to the arrival of the harlequin ladybird Harmonia axyridis

open access: yes, 2011
Changes in UK ladybird species assemblages were assessed during the invasion phase of the alien harlequin ladybird. Harlequins increased from 0.1% (year 1) to 40% (year 3) of total ladybirds sampled, whilst native aphidophagous ladybirds declined from 84%

Effect of a Marking Pheromone and Population Density on Ladybird Larval Development and Adult Body Mass [PDF]

open access: yesInsects
Females 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
