A case of silent invasion : citizen science confirms the presence of Harmonia axyridis (Coleoptera, Coccinellidae) in Central America [PDF]

, 2019
Harmonia axyridis (Coleoptera, Coccinellidae) is a globally invasive ladybird. It has been intentionally introduced in many countries as a biological control agent, whereas it has been unintentionally released in many others.

First record of Hesperomyces virescens (Laboulbeniales, Ascomycota) on Harmonia axyridis (Coccinellidae, Coleoptera) in Poland

Acta Mycologica, 2016
Hesperomyces virescens Thaxt. is a fungal parasite of coccinellid beetles. One of its hosts is the invasive harlequin ladybird Harmonia axyridis (Pallas). We present the first records of this combination from Poland.

Effects of Fluctuating Thermal Regimes and Pesticides on Egg Hatching of a Natural Enemy Harmonia axyridis (Coleoptera Coccinellidae)

Agronomy, 2023
The harlequin ladybird, Harmonia axyridis, is a valuable asset in integrated pest management (IPM); however, issues related to low-temperature storage and transportation have resulted in low hatching rate, while the use of pesticides may lead to non ...

Geographic variation in evolutionary rescue under climate change in a crop pest-predator system. [PDF]

Evol Appl
Abstract Species distribution models (SDMs) are often built upon the “niche conservatism” assumption, such that they ignore the possibility of “evolutionary rescue” and may underestimate species' future range limits under climate change. We select aphids and ladybirds as model species and develop an eco‐evolutionary model to explore evolutionary rescue

Hybrid feature extractor for harlequin ladybird identification using color images [PDF]

2012 IEEE Symposium on Computational Intelligence in Bioinformatics and Computational Biology (CIBCB), 2012
This paper describes research into the automation of the identification of harlequin and other ladybird species using color images. The automation process involves image processing and the use of an artificial neural network as a classifier. The ultimate aim is to reduce the number of color images to be examined by an expert by pre-sorting the images ...

Spiroplasma infection in Harmonia axyridis - Diversity and multiple infection. [PDF]

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%.
