| influence of host gender on infection rate, density and distribution of the parasitic fungus, hesperomyces virescens, on the multicolored asian lady beetle, harmonia axyridis. | hesperomyces virescens thaxter (laboulbeniales: laboulbeniaceae) is a parasitic fungus that infects lady beetles (coleoptera: coccinellidae) via horizontal transmission between adults at overwintering and feeding sites. the differential behavior of male and female hosts could have profound effects on intensity of infection and positioning of fungus on the host's integument. the influence of host gender on infection rate, density and distribution of this parasite on the multicolored asian lady be ... | 2006 | 20298119 |
| infection of harmonia axyridis (coleoptera: coccinellidae) by hesperomyces virescens (ascomycetes: laboulbeniales): role of mating status and aggregation behavior. | the ectoparasitic fungus hesperomyces virescens was studied on harmonia axyridis in north carolina, in the southeastern united states. a primary goal was to investigate transmission of the disease by examining the correlation between the pattern of fungal infection and seasonal change in host behavior. beetles were collected as they arrived at their winter quarters at two sites; in one site they were also subsampled at mid- and late winter. insects were sexed and weighed, fungal thalli were coun ... | 2007 | 17188291 |
| first finding of the parasitic fungus hesperomyces virescens (laboulbeniales) on native and invasive ladybirds (coleoptera, coccinellidae) in south africa. | 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 ... | 2016 | 26861616 |
