Reproduction of parasitic mites Varroa destructor in original and new honeybee hosts

Ecology and Evolution, 2018
The ectoparasitic mite, Varroa destructor, shifted host from the eastern honeybee, Apis cerana, to the western honeybee, Apis mellifera. Whereas the original host survives infestations by this parasite, they are lethal to colonies of its new host.

Unusual Bullous Manifestation of Scabies in Childhood Diagnosed by Dermoscopy: A Case Report

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Scabies is a common ectoparasitic infestation, but atypical variants such as bullous scabies are rare and often misdiagnosed. We report a 12‐year‐old boy who presented with pruritic lesions comprising predominantly vesicles and bullae over the hands, along with a few scattered excoriated papules on the trunk and thighs.

Environmental Drivers on Blue Tit Nest Microbiome: An Experimental Study

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Elevated humidity and temperature altered nest microbial composition and its associations with parasitism and nestling condition. These findings identify nest microclimate as an important driver of nest microbiomes with consequences for avian development.

Norwegian honey bees surviving Varroa destructor mite infestations by means of natural selection [PDF]

PeerJ, 2017
Background Managed, feral and wild populations of European honey bee subspecies, Apis mellifera, are currently facing severe colony losses globally. There is consensus that the ectoparasitic mite Varroa destructor, that switched hosts from the Eastern ...

Leave‐One‐Chromosome‐Out Association Testing Decodes Uncapping Behaviour in Honeybees During Varroa destructor Infestation

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Using an MLM‐LOCO framework with linear and logistic mixed models, we identified three overlapping SNPs and nine candidate genes underlying honeybee's uncapping behavior against Varroa destructor. These robust markers provide a reliable genetic foundation for marker‐assisted breeding of Varroa‐resistant colonies, advancing future sustainable apiculture

Unravelling the Interplay Between Vairimorpha ceranae and Viruses in Geographically Isolated Honey Bee (Apis mellifera) Populations

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Viral infections and the microsporidian Vairimorpha ceranae (‘vairimorpha’) have been involved in elevated honey bee (Apis mellifera) colony losses as a result of their individual or combined actions, with the ectoparasitic mite Varroa destructor (‘varroa’) often exacerbating these effects.
