In honey bees, Varroa sensitive hygiene (VSH) behaviour, which involves the detection and removal of brood parasitised by the mite Varroa destructor, can actively participate in the survival of colonies facing Varroa outbreaks. This study investigated the mechanisms of VSH behaviour, by comparing the antennal transcriptomes of bees that do and do not perform VSH behaviour. Results indicate that antennae likely play a key role in the expression of VSH behaviour. Comparisons with the antennal… 

Expression monitoring of relevant sensitivity genes in honey bee antennae and their relationship with Hygienic Behavior

Investigation of the expression level of selected genes through RealTime-PCR in honeybee antennae finds that Obp3 is the least expressed among the tested genes, but its expression pattern is linked to the HB value; in particular, highly hygienic colonies express Ob p3 significantly at higher rate with respect to the lower HB group of colonies.

Brood Affects Hygienic Behavior in the Honey Bee (Hymenoptera: Apidae).

It is hypothesized that selection for hygienic behavior in honey bees has influenced brood signaling, and predicted that in a common social environment, removal rates differ among brood with different selective breeding histories, and the removal rates of brood positively correlate to the hygiene level of the brood's colony of origin.

Age-performance and intensity of grooming behavior toward Varroa destructor in resistant and susceptible Apis mellifera colonies

It is demonstrated that bee age and genetic origin are critical factors of grooming behavior in honey bees and therefore resistance to honey bees against Varroa destructor is guaranteed.

Varroa-specific hygienic behavior of Apis mellifera scutellata in Kenya

When ten, eight, and five mites were singly introduced in closely neighboring brood cells, hygienic bees were more responsive in the high mite density regime of eight and ten mites, an indication of a possibility that chemicals play a role in identification of Varroa-infested brood cells.

Proteome Analysis of the Hemolymph, Mushroom Body, and Antenna Provides Novel Insight into Honeybee Resistance against Varroa Infestation.

It is illustrated that the enhanced social immunities and olfactory and neuronal sensitivity play key roles in the combat against Varroa infestation to aid in resistance to a parasite responsible for decline in honeybee health.

Honey bees performing varroa sensitive hygiene remove the most mite-compromised bees from highly infested patches of brood

This study identifies features that distinguish cells uncapped by bees performing VSH from infested cells that VSH bees ignore, and is the first to identify cell surrounds as a potential source of signals influencing the behaviour of beesperforming VSH.

Odorant cues linked to social immunity induce lateralized antenna stimulation in honey bees (Apis mellifera L.)

Compared odour profiles of Varroa-infested brood to healthy brood and found an overall interactive effect between developmental stage and infestation, but specific odours did not drive these differences.

Behavioral and molecular studies of quantitative differences in hygienic behavior in honeybees

The better HB colony performance is primarily achieved by a high number of bees engaging in the hygienic tasks that associate with distinct molecular processes in the brain, suggesting that different gene products and pathways may mediate the quantitative genetic differences of HB.

Specific Cues Associated With Honey Bee Social Defence against Varroa destructor Infested Brood

It is shown that varroa-infested brood produce uniquely identifiable cues that could be used by VSH-performing bees to identify with high specificity which brood cells to sacrifice, which is a disease resistance strategy analogous to programmed cell death.

Responses to Varroa by honey bees with different levels of Varroa Sensitive Hygiene

Oviposition of the mite or something associated with mite oviposition provides the stimulus for bees with the VSH trait to remove mite infested pupae.

Two lines of evidence are provided that OA has the potential to facilitate the detection and response of honey bees to diseased brood and its ability to bias the nervous system to express one form of behavior over another.

Social immunity in honeybees (Apis mellifera): transcriptome analysis of varroa‐hygienic behaviour

A set of genes involved in social immunity are identified by analysing the brain transcriptome of highly varroa‐hygienic bees, who efficiently detect and remove brood infected with the Varroa destructor mite.

Viral Infection Affects Sucrose Responsiveness and Homing Ability of Forager Honey Bees, Apis mellifera L.

Evidence is provided that IAPV infection in the heads may enable the virus to disorder foraging roles of honey bees and to interfere with brain functions that are responsible for learning, navigation, and orientation in the honey bees, thus, making honey bees have a lower response threshold to sucrose and lose their way back to the hive.

Physiological and Behavioral Changes in Honey Bees (Apis mellifera) Induced by Nosema ceranae Infection

The effects of infection with a recent honey bee pathogen on physiological factors underlying the division of labor in workers are investigated and disruption of the basic underpinnings of temporal polyethism due to infection may be a contributing factor to recent high colony mortality, as workers may lose flexibility in their response to colony demands.

There is no evidence of task partitioning among bees performing the hygienic behaviour, and the results suggest that the segregation observed could, however, be based on their response thresholds to the stimulus and/or on their ability to discriminate the various cues emanating from the dead brood.

Beekeepers in temperate climates should combine late autumn management strategies with treatment protocols that keep the mite population at low levels before and during the period when the winter bees emerge.

High-Resolution Linkage Analyses to Identify Genes That Influence Varroa Sensitive Hygiene Behavior in Honey Bees

To identify genes influencing Varroa sensitive hygiene behavior, a study was conducted to map quantitative trait loci (QTL) and identified two candidate genes that may allow for breeding bees with this trait using marker-assisted selection.
