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

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 773-785, April 2026.
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

Parasitylenchus sp. (Tylenchomorpha: Allantonematidae) parasitizing field populations of Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2011
Adults of the invasive harlequin ladybird, Harmonia axyridis (Coleoptera: Coccinellidae), were found to be parasitized by nematodes (Tylenchomorpha: Allantonematidae) in Denmark. The nematodes were identified as Parasitylenchus sp.

Spiroplasma infection in Harmonia axyridis - Diversity and multiple infection

open access: yesPLOS ONE, 2018
The heritable endosymbiotic bacterium Spiroplasma is found in the harlequin ladybird Harmonia axyridis. The proportion of beetles infected with Spiroplasma in different native H. axyridis populations varies from 2% to 49%. We investigated the polymorphism of Spiroplasma strains in samples from individual beetles from Kyoto, Vladivostok, Troitsa Bay ...

The presence of micropyles in the shells of developing and undeveloped eggs of the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2009
In Hymenoptera and Heteroptera, the absence of micropyles is one criterion for categorizing an egg as trophic. Undeveloped eggs are observed in more than 90% of the egg clusters of the ladybird beetle Harmonia axyridis Pallas.

Interactions between the Multicolored Asian Lady Beetle Harmonia axyridis and the Parasitoid Dinocampus coccinellae

open access: yesInsects, 2016
Harmonia axyridis (Pallas) has been introduced either intentionally or accidentally in different areas outside its native range, where it is often regarded as invasive. Dinocampus coccinellae (Schrank) has been recorded to parasitize H.

Harlekinmarihøne -Harmonia axyridis

open access: yes, 2008
En invaderende marihøne er på god vei til å etablere seg i Norge. Fra å være observert som tilfeldig blindpassasjer på importplanter i 2006 er harlekinmarihøna (Harmonia axyridis) nå funnet overvintrende på fire lokaliteter i Oslo (2007/2008). Arten er uønsket i Norge fordi den utkonkurrerer andre arter som lever av samme byttedyr som den selv. Den har

Effects of starvation on the carbohydrate metabolism in Harmonia axyridis (Pallas)

open access: yesBiology Open, 2017
Trehalose plays an important role in energy storage, metabolism, and protection from extreme environmental conditions in insects. Trehalose is the main ‘blood’ sugar in insects, and it can be rapidly used as an energy source in times of need. To elucidate the mechanisms of the starvation response, we observed the effects of starvation on trehalose and ...
