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

Parasite, 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

Phylogenetic Analyses of True Ladybirds (Coleoptera: Coccinellidae: Coccinellini) Reveal Directionality in Diet Evolution and Support a Boreotropical Origin of the Tribe

Ecology and Evolution, Volume 16, Issue 4, April 2026.
A newly generated large‐scale molecular phylogeny of true ladybirds (Coccinellini) clarifies their evolutionary relationships and supports a boreotropical origin in the Paleocene, with multiple independent southward dispersals. Ancestral diet reconstructions suggest an initial specialization on aphids, followed by expansions in host range and ...

Evaluating the potential of RNA interference for control of striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae)

Pest Management Science, Volume 82, Issue 4, Page 3591-3602, April 2026.
SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...

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

Functional 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

Pollen as an alternative food for Harmonia axyridis

BioControl, 2007
The current study examines the potential of the multicoloured Asian lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) to use pollen as a food to sustain development and reproduction in the absence of insect prey. Three populations of H.
