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

Arch Insect Biochem Physiol
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

Mitochondrial COI and cytb Characterisation of K-Lineage Varroa destructor Isolates From Kastamonu, Türkiye. [PDF]

Vet Med Sci
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.

An Insight Into the microRNA Profile of the Ectoparasitic Mite Varroa destructor (Acari: Varroidae), the Primary Vector of Honey Bee Deformed Wing Virus

Frontiers in Cellular and Infection Microbiology, 2022
The remarkably adaptive mite Varroa destructor is the most important honey bee ectoparasite. Varroa mites are competent vectors of deformed wing virus (DWV), and the Varroa-virus complex is a major determinant of annual honey bee colony mortality and ...

Standard Methods for Dissection of Varroa destructor Females [PDF]

Insects, 2021
Varroa destructor (Anderson and Trueman) is known as a major pest of Apis mellifera L, especially in the Northern Hemisphere where its effects can be deleterious. As an obligate parasite, this mite relies entirely on its host to reproduce and complete its cycle. Studies focusing on isolated organs are needed to better comprehend this organism.

Control of Varroa Destructor in Kazakhstan.

Archives of Razi Institute, 2021
Varroa mite is one of the most dangerous bee parasites and causes a lot of damage to the beekeeping industry. Several chemical and herbal medicines have been used to control this mite so far. In this study, the effects of Artemisia absinthium and Hypericum perforatum prescription to control Varroa mite were investigated. To this end, a total of 380 bee

Edge-Based Detection of Varroosis in Beehives with IoT Devices with Embedded and TPU-Accelerated Machine Learning

Applied Sciences, 2021
One of the causes of mortality in bees is varroosis, a bee disease caused by the Varroa destructor mite. Varroa destructor mites may occur suddenly in beehives, spread across them, and impair bee colonies, which finally die. Edge IoT (Internet of Things)

Detection of Varroa destructor Infestation of Honeybees Based on Segmentation and Object Detection Convolutional Neural Networks

AgriEngineering, 2023
Varroa destructor infestation is a major factor leading to the global decline of honeybee populations. Monitoring the level of Varroa mite infestation in order to take timely control measures is crucial for the protection of bee colonies.

Genotype, but Not Climate, Affects the Resistance of Honey Bees (Apis mellifera) to Viral Infections and to the Mite Varroa destructor

Veterinary Sciences, 2022
This study was conducted to analyze the effect of genotype and climate on the resistance of honey bee (Apis mellifera) colonies to parasitic and viral diseases. The prevalence and intensity of parasitism by Varroa destructor, or infection by Nosema spp.,
