Deformed wing virus (DWV) is a lethal virus of honeybees (Apis mellifera) implicated in elevated colony mortality rates worldwide and facilitated through vector transmission by the ectoparasitic mite Varroa destructor. Clinical, symptomatic DWV infections are almost exclusively associated with high virus titres during pupal development, usually acquired through feeding by Varroa mites when repr...

The ectoparasitic Varroa destructor mite is a major contributor to the ongoing honey bee health crisis. Varroa interacts with honey bee viruses, exacerbating their pathogenicity. In addition to vectoring viruses, immunosuppression of the developing honey bee hosts by Varroa has been proposed to explain the synergy between viruses and mites. However, the evidence for honey bee immune suppression...

A mathematical model was proposed and analysed to study the dynamics of a system prey, primary predator super in which predators show Holing Type II functional response their respective prey. The substantially provides mechanism for improving survivability honeybee population halt negative impact Varroa-mite infestation on by introducing Pseudoscorpion serve as Varroa-mite. Also, significantly ...

Honey bee colonies (Apis mellifera carnical, infested with Varroa jacobsonl were de-queened and divided into 2 subunits. Each pair of subunits were requeened with an inseminated A m capensis and A m carnica queen. The development of the mite population was monitored by determining the number of mites in samples of brood, and worker bees, and lhe number of dead mites on the bottom board of the h...

grooming behaviour is one of the important mechanisms of honeybee defence against parasitic mites. in addition to genetical characteristics, environmental conditions affect the behavioural traits of honeybee colonies. the main objective of this study was to examine the effect of temperature and humidity on the ability of honeybee workers to remove varroa mites from their body. one hundred worke...

We investigated pathogens in the parasitic honeybee mite Varroa destructor using nanoLC-MS/MS (TripleTOF) and 2D-E-MS/MS proteomics approaches supplemented with affinity-chromatography to concentrate trace target proteins. Peptides were detected from the currently uncharacterized Varroa destructor Macula-like virus (VdMLV), the deformed wing virus (DWV)-complex and the acute bee paralysis virus...

BACKGROUND The Varroa destructor mite is considered as a major pest of honey bees Apis mellifera. The rapid spread of Varroa mites among bee colonies may be due to several factors, including drifting of infested bees, movement of bee swarms, and robbing of weakened colonies. Disease spread and predisposing the infested bees to other diseases lead to high economic losses in beekeeping industries...

The hive of the honey bee is a suitable habitat for diverse mites (Acari), including nonparasitic, omnivorous, and pollen-feeding species, and parasites. The biology and damage of the three main pest species Acarapis woodi, Varroa jacobsoni, and Tropilaelaps clareae is reviewed, along with detection and control methods. The hypothesis that Acarapis woodi is a recently evolved species is rejecte...

Honey bees (Apis melliferaL.) (Hymenoptera: Apidae) have been selectively bred for varroa-sensitive hygiene (VSH), which is the removal of pupae that are infested byVarroa destructor Anderson&Trueman fromcappedbrood cells. This hygienic behavior is a complex interactionof bees and brood inwhich brood cells are inspected, and then brood is either removed or recapped. Previous work has shown that...

Varroa mites (Varroa destructor) are ectoparasites of honey bees (Apis mellifera) and cause serious damage to bee colonies. The mechanism of how varroa mites kill honey bees remains unclear. We have addressed the effects of the mites on bee immunity and the replication of a picorna-like virus, the deformed wing virus (DWV). The expression of genes encoding three antimicrobial peptides (abaecin,...
