Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales) that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird Harmonia axyridis and for its potential use in studies of co-evolution and pathogen spread. We collected adults from ten species of ladybirds in the Western Cape Province, South Africa, and screened for the presence of H. virescens. Infections with H. virescens were found in the samples of two species, H. axyridis and the native Cheilomenes propinqua. This marks the first record of H. virescens on H. axyridis from the African continent and the first record on Cheilomenes worldwide.
Résumé
Hesperomyces virescens est un ectoparasite fongique (Laboulbeniales) qui infecte les coccinelles adultes. La recherche a récemment mis l’accent sur ce parasite en raison de la découverte de sa prévalence sur la coccinelle asiatique Harmonia axyridis, invasive au niveau mondial, et pour son utilisation potentielle dans les études de co-évolution et de propagation des pathogènes. Nous avons recueilli les adultes de dix espèces de coccinelles dans la province du Cap occidental, Afrique du Sud et recherché la présence de H. virescens. Des infections à H. virescens ont été trouvées dans les échantillons de deux espèces, H. axyridis et Cheilomenes propinqua, une espèce indigène. Ceci est la première mention de H. virescens sur H. axyridis sur le continent africain et la première mention sur Cheilomenes dans le monde.
