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. However, insecticides are widely used to control aphid pests worldwide and the potential non-target effects ...

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. Biocontrol agents are believed to be a less damaging alternative than pesticides, but some species may also prey on or parasitize native species or outcompete them for resources.

Global patterns of genomic and phenotypic variation in the invasive harlequin ladybird. [PDF]

BMC Biol, 2023
AbstractBackgroundThe harlequin ladybirdHarmonia axyridis(Coleoptera: Coccinellidae), native to Asia, has been introduced to other major continents where it has caused serious negative impacts on local biodiversity. Though notable advances to understand its invasion success have been made during the past decade, especially with then newer molecular ...

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

Curr Biol, 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 ...

Fifty Shades of the Harlequin Ladybird and a Sexually Transmitted Fungus. [PDF]

J Insect Sci, 2019
AbstractThe ectoparasitic fungus Hesperomyces virescens was studied on its invasive host, the harlequin ladybird Harmonia axyridis, in the Czech Republic. A primary aim was to examine the relationship between fungal infection and elytral coloration of the ladybird. Furthermore, the role of host sex and mating status of females were analyzed. Beetles (n

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

iScience
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) imaging and RNA-seq to examine wing growth and transcriptome profiles across juvenile stages in the Locusta ...

Cannibalism in invasive, native and biocontrol populations of the harlequin ladybird. [PDF]

BMC Evol Biol, 2014
Cannibalism is widespread in both vertebrates and invertebrates but its extent is variable between and within species. Cannibalism depends on population density and nutritional conditions, and could be beneficial during colonisation of new environments. Empirical studies are needed to determine whether this trait might facilitate invasion of a new area

The interaction of <i>Serratia</i> bacteria and harmonine in harlequin ladybird confers an interspecies competitive edge. [PDF]

Proc Natl Acad Sci U S A
The harlequin ladybird, Harmonia axyridis , is a predatory beetle used globally to control pests such as aphids and scale insects. Originating from East Asia, this species has become highly invasive since its introduction in the late 19th century to Europe and North America, posing a threat to local biodiversity ...
