The antioxidant defense system of Varroa destructor mites facilitates the infestation of Apis mellifera

open access: yesJournal of Apicultural Science, 2016
Varroa destructor is a parasitic mite of the Western honey bee. The activity of five antioxidant enzymes of V. destructor were analysed. Glutathione content and total antioxidant status was also evaluated.

Impacts of a Sweet Orange Essential Oil–Based Biopesticide on Exorista larvarum, a Parasitoid Tachinid Fly With a Dual Role

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 933-941, August 2026.
Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.

Behavioral Resistance in Varroa destructor: First Evidence in Response to Acaricide?

open access: yesArchives of Insect Biochemistry and Physiology, Volume 122, Issue 3, July 2026.
Varroa mites exhibited population‐dependent behavioral responses: two populationw avoided tau‐fluvalinate, and none showed specific behavioral responses to amitraz and oxalic acid, despite contrasting phenotypical resistance profiles. ABSTRACT The ectoparasite Varroa destructor (Mesostigmata: Varroidae) poses a major threat to honey bee colonies due to

Varroa destructor Mites Can Nimbly Climb from Flowers onto Foraging Honey Bees. [PDF]

open access: yesPLoS ONE, 2016
Varroa destructor, the introduced parasite of European honey bees associated with massive colony deaths, spreads readily through populations of honey bee colonies, both managed colonies living crowded together in apiaries and wild colonies living widely ...

Mitochondrial COI and cytb Characterisation of K‐Lineage Varroa destructor Isolates From Kastamonu, Türkiye

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study provides the molecular characterisation and phylogenetic analysis of Varroa destructor collected in Kastamonu, Türkiye. Using mitochondrial COI and cytb markers, the research identifies an identical K‐lineage, offering critical insights into the genetic diversity and evolutionary relationships within the region's mite populations.

Predictive markers of honey bee colony collapse.

open access: yesPLoS ONE, 2012
Across the Northern hemisphere, managed honey bee colonies, Apis mellifera, are currently affected by abrupt depopulation during winter and many factors are suspected to be involved, either alone or in combination.

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

open access: yesVeterinary 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

open access: yesEvolutionary 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.

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.
