The Rational Use of Oxalic Acid Against to “Varroa Destructor”; Regional Scale Pilot Scheme

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2023
Varroa destructor mite poses a serious problem for the future of bee populations around the world. Today, there are many commercial drugs with the same and different active ingredients on the market to chemically control over of Varroa destructor.

Towards integrated control of varroa: effect of variation in hygienic behaviour among honey bee colonies on mite population increase and deformed wing virus incidence [PDF]

open access: yes, 2014
Hygienic behaviour in the honey bee, Apis mellifera, is the uncapping and removal of dead, diseased or infected brood from sealed cells by worker bees. We determined the effect of hygienic behaviour on varroa population growth and incidence of deformed ...

Surveillance of Viruses in Varroa destructor Samples Collected from Honey Bee Colonies in Ontario, Canada, between 2015 and 2019

open access: yesJournal of Apicultural Science, 2022
Varroa destructor parasitism is associated with extreme honey bee (Apis mellifera) colony losses in the northern hemisphere. Varroa destructor causes severe damage, including a decrease in bee longevity and immunosuppression, and acts as a vector for ...

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]

open access: yes, 2008
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.

Sustainable varroa mite (Varroa destructor) control in field conditions

open access: yesActa Veterinaria Brno, 2022
Experiments assessed the comparative efficacy of oxalic acid solution (OA) and combination of formic acid (FA) evaporation and trickling OA to control the honey bee mite, Varroa destructor, at two apiary locations. Queen caging, consecutive OA treatments of broodless colonies, or combined treatments using OA and FA in colonies with brood increased mite

LAMP (Loop-mediated isothermal amplification) assay for rapid identification of Varroa mites

open access: yesScientific Reports, 2023
Varroa mites are serious pests of European honeybees (Apis mellifera). For detection of Varroa mite, a new molecular LAMP-based assay has been developed, which retains the body of the mite intact for morphological identification.
