Environmental DNA Methods for Detection of Varroa destructor in Honey Bee (Apis mellifera) Hives

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
The parasitic mite, Varroa destructor, is a worldwide problem for honey bees (Apis mellifera). Using a new species‐specific qPCR assay, we assessed the detection of V. destructor eDNA collected in honey and surface swabs from managed bee hives in Australia, where V. destructor has recently invaded, and in New Zealand, where V. destructor is established.

Sequence‐Based Multi Ancestry Association Study Reveals the Polygenic Architecture of Varroa destructor Resistance in the Honeybee Apis mellifera

open access: yesMolecular Ecology, Volume 34, Issue 3, February 2025.
ABSTRACT Honeybees, Apis mellifera, have experienced the full impacts of globalisation, including the recent invasion by the parasitic mite Varroa destructor, now one of the main causes of colony losses worldwide. The strong selection pressure it exerts has led some colonies to develop defence strategies conferring some degree of resistance to the ...
