Antennal sensory organs and glands of the harlequin ladybird, Harmonia axyridis
Entomologia Experimentalis et Applicata, 2020AbstractHarmonia axyridis (Pallas) (Coleoptera: Coccinellidae) is a sub‐cosmopolitan species. Native to Asia, it has been released during the 20th century for classical and augmentative biological control of several herbivorous insects, mostly aphids and coccids. Despite its recognized positive impact on biological control, H.

This paper describes recent work in the UK to automate the identification of Harlequin ladybird species Harmonia axyridis using color images. The automation process involves image processing and the use of probabilistic neural network PNN as classifier, with an aim to reduce the number of color images to be examined by entomologists through pre-sorting

Can contamination by major systemic insecticides affect the voracity of the harlequin ladybird?
Chemosphere, 2020Systemic neurotoxic insecticides are widely used to control aphid pests worldwide and their potential non-target effects on aphid predators are often unknown. Behavioral responses linked to biological control services are crucial when assessing the compatibility of chemicals with biocontrol organisms.

A Field Guide to Harlequins and Other Common Ladybirds of Britain and Ireland
2021The invasive Harlequin ladybird is an eye-catching and beautiful species, but it can be very difficult to identify, with huge variation in colouration and pattern. This comprehensive photographic field guide is the first complete guide to identifying Harlequin ladybirds found in Britain and Ireland. It also covers all the other 25 conspicuous ladybird

Comments by de Jong et al ., Solter et al ., and Sloggett question the ecological relevance of the abundant microsporidia found in the invasive ladybird Harmonia axyridis . We contend that there is abundant evidence that native ladybirds feed on H. axyridis

We evaluated the status of native ladybird assemblages in the presence of the non-native ladybird Harmonia axyridis Pallas (Coleoptera: Coccinellidae) in three European countries. To achieve this, we assessed the abundance of ladybirds from common host plants in urban areas of Great Britain, Czech Republic and Slovak Republic in 2014. We determined (i)

Entomological Review, 2015
The harlequin ladybird Harmonia axyridis (Pallas, 1773) is one of the most famous invasive beetles in the world. A map of 105 findings of H. axyridis in Western Siberia, Kazakhstan, and northwestern China was compiled based on the examination of museum collections (about 1000 spec.) and analysis of the published data.
