First finding of the parasitic fungus Hesperomyces virescens (Laboulbeniales) on native and invasive ladybirds (Coleoptera, Coccinellidae) in South Africa

open access: yesParasite, 2016
Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales) that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird Harmonia axyridis and for its

The Rare Five-Spot Ladybird Coccinella quinquepunctata (Coleoptera: Coccinellidae) Surviving in an Unstable Habitat

open access: yesFrontiers in Conservation Science, 2022
Coccinella quinquepunctata (the five-spot ladybird), was considered extinct in the UK until 1987. Since this time the species is abundant, however, only in very specific habitat in Wales and Scotland.

The harlequin ladybird, Harmonia axyridis: global perspectives on invasion history and ecology [PDF]

open access: yesBiological Invasions, 2016
The harlequin ladybird, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is native to Asia but has been intentionally introduced to many countries as a biological control agent of pest insects. In numerous countries, however, it has been introduced unintentionally. The dramatic spread of H.

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Heating up parasitoid–host interactions: High temperature increased mortality of late‐instar braconid larvae and reduced ladybird recovery rate

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract With ongoing climate change, temperature‐dependent outcomes of host–parasitoid interactions can affect ecosystem functioning and key ecosystem services such as biological control. However, most studies addressing the impacts of temperature on host–parasitoid systems are

Sex‐Specific doublesex Regulation Targeting the Color‐Patterning Gene h Underlies the Evolution of Wing Sexual Dimorphism in the Harlequin Ladybug Harmonia axyridis

open access: yesEvolution &Development, Volume 28, Issue 1, March 2026.
doublesex regulates sexual dimorphism in elytral color patterns of Harmonia axyridis by downregulating the color patterning gene h in males. This regulatory link diverged in derived color morphs, coinciding with the loss of sex‐specific elytral color patterns.

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.

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

open access: yesInsect Conservation and Diversity, Volume 19, Issue 2, Page 452-459, March 2026.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Effects of temperature and humidity on the presence and prevalence of a common fungal parasite on an invasive ladybird

open access: yesEcological Entomology, Volume 51, Issue 1, Page 86-97, February 2026.
We investigated how temperature and relative humidity influence the parasitic fungus Hesperomyces harmoniae on the invasive ladybird Harmonia axyridis under controlled laboratory conditions. Abiotic factors significantly affect parasitism: High relative humidity increased parasite prevalence, development rate, and load, while both low and high ...

Pisana polonica (Harmonia axyridis [Pallas], Coleoptera, Coccinellidae) - invazivna koristna vrsta

open access: yesActa Agriculturae Slovenica, 2012
V začetku novembra 2011 smo v okolici Ljubljane na zidovih posameznih stanovanjskih hiš opazili množičen pojav polonic. Nekaj primerkov smo izlovili, da bi določili vrsto.
