Antennae transcriptomics of Varroa-hygienic and Nurse/Forager bees


ABSTRACT: The Varroa mite represents the main threat of honey bees (Apis mellifera). Bees from some colonies can limit the proliferation of this parasite by detecting and removing parasitized brood, such behavior is defined as Varroa sensitive Hygiene (VSH). This is an important issue for selecting colonies that can survive Varroa outbreaks. We therefore study the molecular meachnisms underlying this behavior by comparing the antennae transcriptomic profile of VSH and non-VSH bees. Those profiles were further compared to to the profiles of nurses and forager profiles involved in brood care and food collection, respectively. Overall design: mRNA profiling of bees performing or not Varroa hygienic behavior (4 replicates) and nurse and forager bees (2-3 replicates)

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 tran  ...[more]
