European Journal of Entomology, 2013 This is the first record of the harlequin ladybird Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) occurring in the Caucasus (Sochi region of Krasnodar territory, Russia). All the adults collected in the field there and reared from collected eggs,

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 ...

Reproduction in Risky Environments: The Role of Invasive Egg Predators in Ladybird Laying Strategies. [PDF]
PLoS ONE, 2015 Reproductive environments are variable and the resources available for reproduction are finite. If reliable cues about the environment exist, mothers can alter offspring phenotype in a way that increases both offspring and maternal fitness ('anticipatory

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 ...

Gender and timing during ontogeny matter: effects of a temporary high temperature on survival, body size and colouration in Harmonia axyridis. [PDF]
PLoS ONE, 2013 The ambient temperature experienced during development is a crucial factor affecting survival and adult phenotype in ectotherms. Moreover, the exact response of individuals to different temperature regimes is frequently sex-specific.

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.

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 ...
