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

Insects, 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.

Assessment of the Harlequin Ladybird's (Harmonia Axyridis) Resistance to the Most Commonly Used Active Substances in Insecticides

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2021
The objective of this study was to find out if useful insects - in this case, harlequin ladybirds (Harmonia axyridis) - are affected by plant protection products (PPP) to the same extent as pests and if this species shows any levels of resistance to ...

Increase in male reproductive success and female reproductive investment in invasive populations of the harlequin ladybird Harmonia axyridis. [PDF]

PLoS One, 2013
Reproductive strategy affects population dynamics and genetic parameters that can, in turn, affect evolutionary processes during the course of biological invasion.

Comment on “Invasive Harlequin Ladybird Carries Biological Weapons Against Native Competitors” [PDF]

Science, 2013
We comment on the implications that Vilcinskas et al . (Reports, 17 May 2013, p. 862) attach to the finding that the exotic, invasive ladybird Harmonia axyridis carries microsporidia to which this species is insensitive but that is lethal to species that are native to the invaded areas.

Harmonia axyridis (Coleoptera: Coccinellidae) in Serbia: Its presence on aphid-infested plants and co-occurrence with native aphidophagous coccinellids [PDF]

Pesticidi i Fitomedicina, 2020
The presence of the invasive coccinellid Harmonia axyridis in aphid colonies on plants, as well as its co-occurrence with native coccinellid predators was studied in the period 2011-2020.

First record of Hesperomyces virescens (Laboulbeniales, Ascomycota) on Harmonia axyridis (Coccinellidae, Coleoptera) in Poland

Acta Mycologica, 2016
Hesperomyces virescens Thaxt. is a fungal parasite of coccinellid beetles. One of its hosts is the invasive harlequin ladybird Harmonia axyridis (Pallas). We present the first records of this combination from Poland.

Light Intensity Modulates Locomotor Behavior and Predation in Different Color Morphs of the Harlequin Ladybird, <i>Harmonia axyridis</i>. [PDF]

Insects
Light is a fundamental ecological cue for insects, influencing physiological rhythms and behavior. We investigated how varying light intensities affect locomotion and foraging in H. axyridis color morphs, and examined the role of visual opsins.

Double Infections of the Invasive Ladybird Harmonia axyridis

Frontiers 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 ...

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.
