Harmonia axyridis ladybug invasion and allergy.
Beginning in 1916 Harmonia axyridis, an orange/red lady beetle with variable black spotting, was imported into the United States from Asia. This agricultural pest-control predator established independent feral populations in North America by 1988. Subsequently, Harmonia axyridis has become a pest to homeowners and various horticultural enterprises. Seeking winter hibernation sites, ladybug swar...
متن کاملAggregation behavior of Harmonia axyridis under non-wintering conditions.
The invasive multicolored Asian ladybeetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), aggregates inside dwellings during winter to avoid cold weather. This adaptive behavior disturbs homeowners, because of the large numbers of individuals that aggregate, which induces allergic reactions. The migratory flight patterns of this species have been well documented, with individuals pref...
متن کاملThe effect of the coccinellid Harmonia axyridis (Coleoptera: Coccinellidae)
The coccinellid Harmonia axyridis is a recent arrival in the UK and is an intraguild predator of the entomopathogenic fungus Pandora neoaphidis. Harmonia axyridis entirely consumes P. neoaphidis-sporulating cadavers and this may have a negative effect on the epizootic potential of P. neoaphidis. Here we assessed within plant transmission, and between plant vectoring, of P. neoaphidis in the pre...
متن کاملHarmonia axyridis ladybug hypersensitivity in clinical allergy practice.
The imported Harmonia axyridis ladybug infests homes in northern West Virginia from fall through spring, causing allergic disease. Retrospective single-practice chart reviews were performed: (1) all skin prick tests (1400 included ladybug) in a community allergy practice over 4 years and (2) clinical analysis of 400 randomly chosen patients. The usual adult aeroallergen skin test panel included...
متن کاملInbreeding Depression Is Purged in the Invasive Insect Harmonia axyridis
Bottlenecks in population size reduce genetic diversity and increase inbreeding, which can lead to inbreeding depression. It is thus puzzling how introduced species, which typically pass through bottlenecks, become such successful invaders. However, under certain theoretical conditions, bottlenecks of intermediate size can actually purge the alleles that cause inbreeding depression. Although th...
