Contribution of individual legs to overall attachment in the adult ladybird Harmonia axyridis depends on the relative leg orientation to an external force

Entomologia Experimentalis et Applicata, Volume 173, Issue 3, Page 232-245, March 2025.
We investigated harlequin ladybird, Harmonia axyridis (Coleoptera: Coccinellidae), attachment ability focusing on the synergic action of opposite legs, the anisotropy of adhesive organs and sexual dimorphism. Experiments showed that beetles with fewer legs sometimes exhibited higher attachment forces, challenging the hypothesis that collective leg ...

Repeated Copulation and Guarding, and Their Relationship With Male and Female Morphological Traits in the Water Scorpion Nepa hoffmanni

Ecology and Evolution, Volume 14, Issue 12, December 2024.
We describe for the first time the detailed mating behaviour and patterns of repeated copulations in the water scorpion Nepa hoffmanni (Nepidae, Hemiptera). Over repeated copulations, copulation duration decreased while guarding duration increased. Additionally, we found that average guarding duration was positively associated with male leg length and ...

The harlequin ladybird Harmonia axyridis – Sensory thresholds of the “ladybird taint” in wine under different processing conditions

Nature Precedings, 2011
AbstractIntroduced as a biological control agent in North America and middle Europe the Harlequin Ladybird Harmonia axyridis has spread all over the countries and are capable to become an increasing problem for winegrowers and also households. Due to its preference to overwinter indoors H.

Automatic Potato Crop Beetle Recognition Method Based on Multiscale Asymmetric Convolution Blocks

Agronomy
Five beetle species can occur in potato fields simultaneously, including one quarantine pest (the Colorado potato beetle (CPB)), one phytophagous pest (the 28-spotted potato ladybird beetle), and three predatory ladybird beetles (the 7-spotted lady ...

A role of epigenetic mechanisms in regulating female reproductive responses to temperature in a pest beetle

Insect Molecular Biology, Volume 33, Issue 5, Page 516-533, October 2024.
Temperature‐dependent, epigenetic impacts on life history components, after treatment with putatively epimutating drugs (3‐aminobenzamide [3AB] hypermethylating, and Zeb hypomethylating). Upward arrows depict increased fitness of treated females, whereas downward arrows depict fitness costs of treatment, relative to fitness of water‐treated controls ...

Current evidence of climate‐driven colour change in insects and its impact on sexual signals

Ecology and Evolution, Volume 14, Issue 7, July 2024.
Our review will provide current information about how climatic factors, such as temperature, precipitation, and humidity impact on insect's colour and sexual signals. In addition, we discussed about the counter mechanisms that insects usually take place to adapt with the changing climate.

Harmonia axyridis (Boyer de Fonscolombe) (Hemiptera: Coccoidea) as a potential biological control agent of the invasive soft scale, Sphaerolecanium prunastri (Boyer de Fonscolombe) (Hemiptera: Coccoidea) in native wild apricot forests

Egyptian Journal of Biological Pest Control
Background The globose scale (GS), Sphaerolecanium prunastri (Boyer de Fonscolombe) (Hemiptera: Coccoidea), has invaded wild apricot forests in their native range in Central Eurasia threatening the ancestral germplasm resource.

Effects of so-called "environmentally friendly" agrochemicals on the harlequin ladybird Harmonia axyridis (Coleoptera: Coccinel[l]idae)

European Journal of Entomology, 2019
A variety of plant protection products and other agrochemicals are used in agro-ecosystems. Products approved for integrated pest management (IPM) or organic farming should have minimal negative side effects on beneficial insects.
