Sexual Dimorphism of Tarsal Attachment Devices and Their Relation to Mating in Coccinellidae
Journal of Morphology, Volume 286, Issue 4, April 2025.We explore the coevolution of male attachment devices and female elytral morphology in coccinellids. Specifically: (1) Disco‐setae are present in males of some species, located on the hairy pad which during mating hold on female elytra. (2) The area of male disco‐setae is extended when females have smooth elytra, and reduced when females have hairy ...

Spiroplasma infection in Harmonia axyridis - Diversity and multiple infection
PLOS 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 ...

Evaluation of Ecological Service Function in Cotton‐Based Multiple Cropping Systems
Food and Energy Security, Volume 14, Issue 2, March/April 2025.In our research, four cotton‐based cropping systems combined with chemical control were set for screening the reasonable cropping systems along with the Yellow River basin through evaluating ecological service value. Garlic‐cotton rotation with environmentally friendly and high efficiency was suitable for applying in cotton fields around the Yellow ...

Microscopy Research and Technique, Volume 88, Issue 3, Page 761-780, March 2025.This research described the ultrastructural organization of Coccinellidae maxillary palps. The apical sensory area housed the largest number of sensilla. The sensilla belonged to three types: uniporous, multiporous, and campaniform sensilla. Large number of sensilla and sensory neurons provide evidence that maxillary palps act as primary sensory organ ...

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 ...
