Urbanization Negatively Affects the Species Composition of Native Ladybirds in Central Europe

open access: yesFrontiers in Conservation Science, 2021
We evaluated the differences in frequency (percentage of sampling sessions where the species was recorded) and abundance (mean number of individuals per 100 sweeps) of native species of ladybirds (Coleoptera: Coccinellidae) in the center of Prague ...

Molecular evolution of dietary shifts in ladybird beetles (Coleoptera: Coccinellidae): from fungivory to carnivory and herbivory [PDF]

open access: yesBMC Biology
Background Dietary shifts are major evolutionary steps that shape ecological niches and biodiversity. The beetle family Coccinellidae, commonly known as ladybirds, first transitioned from a fungivorous to an insectivorous and subsequently a plant diet ...

Influence of Host Species, Location, and Aphid Prey on Microbial Diversity and Community Dynamics of Aphidophagous Ladybird Beetles in Guangxi, China [PDF]

open access: yesEcology and Evolution
Host species, locations, and diet can significantly impact microbial diversity and community in insects. Several ladybird beetles are known as key predators and potential biological control agents for aphids.

Geographic variation in evolutionary rescue under climate change in a crop pest–predator system [PDF]

open access: yesEvolutionary Applications
Species distribution models (SDMs) are often built upon the “niche conservatism” assumption, such that they ignore the possibility of “evolutionary rescue” and may underestimate species' future range limits under climate change.

Exotic predators are not better biocontrol agents: the harlequin ladybird is not the most voracious in Mexico [PDF]

open access: yesPeerJ, 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.

Treating green pea aphids, Myzus persicae, with azadirachtin affects the predatory ability and protective enzyme activity of harlequin ladybirds, Harmonia axyridis

open access: yesEcotoxicology and Environmental Safety, 2021
As a natural enemy of green peach aphids, harlequin ladybirds, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), are also indirectly affected by azadirachtin.

Long Term Monitoring in Switzerland Reveals That Adalia bipunctata Strongly Declines in Response to Harmonia axyridis Invasion

open access: yesInsects, 2020
A long-term monitoring was conducted at 40 sites in four different habitats in north-western Switzerland to observe changes in populations of native ladybirds, following the invasion of the Asian harlequin ladybird, Harmonia axyridis.

Effect of Ingestion Exposure of Selected Insecticides on Coccinella septempunctata and Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesInsects, 2021
The sensitivity to thiacloprid and lambda-cyhalothrin ingested from prey organisms was studied in Coccinella septempunctata and Harmonia axyridis, since the effect of ingestion exposure to these insecticides is unknown in these species. All developmental

Warm Mesoclimate Advances the Seasonal Dynamics of Harmonia axyridis in Urban Habitats

open access: yesFrontiers in Ecology and Evolution, 2021
In 2016–2019, seasonal changes in the abundance of the harlequin ladybird Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) were established in the city center of Prague, Central Europe, and in its outskirts.

Overwintering of ladybirds (Coleoptera: Coccinellidae) on Scots pine in Central Europe

open access: yesEuropean Journal of Entomology, 2018
We surveyed ladybirds (Coleoptera: Coccinellidae) in 10 stands of Scots pine (Pinus sylvestris), all monoculture stands 5-100 years old, in western Slovakia, Central Europe, over two successive periods, October 2013 - March 2014 and October 2014 - March ...
