Identification of limonene as a potential kairomone of the harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae)

European Journal of Entomology, 2010
Chemical cues involved in both host location and oviposition by Harmonia axyridis Pallas (Coleoptera: Coccinellidae) were investigated in laboratory and field experiments.

Predator cues from jumping spiders modulate herbivore behaviour and reduce plant damage

Ecological Entomology, EarlyView.
Jumping spider cues increase immobility and delay first reproduction in the aphid Myzus persicae. Spider cues reduce leaf consumption by chewing herbivores, indicating reduced herbivore pressure on plants. Jumping spider cues may mediate indirect effects across trophic levels by altering herbivore behaviour and plant–herbivore interactions.

Can Airborne eDNA Be Used to Assess the Impacts of Invasive Species on Biodiversity?

Environmental DNA, Volume 8, Issue 6, November‐December 2026.
We sequenced airborne eDNA to target plant and arthropod communities in woodlands with an invasive forest pest present and woodlands with no known infestations. We did not find differences in plant communities; however, we found site differences in the arthropod communities between the infested and non‐infested sites.

Species‐specific reduction of survival and predation in ladybirds exposed to prolonged and intensified heat waves

Ecology, Volume 107, Issue 10, October 2026.
Abstract Climate change exacerbates heat waves, threatening ecosystems by disrupting species survival and interactions. Insects are highly sensitive to temperature extremes, exhibiting species‐specific stress which can impact community dynamics. Ecosystem services, such as pest control, can therefore be reduced by heat stress.

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, Volume 82, Issue 9, Page 8499-8511, September 2026.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Actions on mammalian and insect nicotinic acetylcholine receptors of harmonine-containing alkaloid extracts from the harlequin ladybird Harmonia axyridis [PDF]

, 2020
The harlequin ladybird, Harmonia axyridis (H. axyridis), possesses a strong chemical defence that has contributed to its invasive success. Ladybird beetle defensive chemicals, secreted in response to stress and also found on the coating of laid eggs, are
