Transcriptome of Varroa destructor life cycle

Project description:To study the underlying molecular mechanisms during the Varroa destructor life cycle, we carried out transcriptomic profiling of seven stages: young mites (collected from P8 to P9 brood cells), phoretic mites (collected on adult bees), arresting mites (collected in unsealed L5 brood cells), pre-laying mites (collected from sealed brood cells containing moving larva), laying mites (collected from sealed brood cells containing pre-pupae), post-laying mites (collected from capped brood cells containing purple-eye and white-body pupae P5), emerging mites (collected from P8 to P9 brood cells). In addition, we sampled non-reproducing mites (collected from P5 brood cells, but without offspring), males (collected from P8 to P9 brood cells), and phoretic mites artificially reared in cages with adult bees. This study was performed using Apis mellifera L. honey bee colonies naturally infested by Varroa destructor mites. Adult mites were collected from 4 unrelated colonies.

Antennae transcriptomics of Varroa-hygienic and Nurse/Forager bees

Project description: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.

Brain transcriptomics of honey bee parasitized by Varroa destructor or Nosema ceranae

Project description:In this study we addressed whether the transcriptome profile in the honey bee brain is similar for two major parasites of honey bee, Varroa destructor and Nosema ceranae. Honey bees parasitized by these two parasites show accelerated behavioral maturation and deficiences in orientation and learning/memory that we hoped to characterized at the transcriptomic level. honey bee adults infested by Varroa destructor or Nosema ceranae compared to control bees, in duplicate

Omics-based analysis of honey bee (Apis mellifera) response to Varroa sp. interaction reveals changes impairing the winter bee generation

Project description:Extensive annual losses of honey bees (Apis mellifera L.) represent a global problem for agriculture and biodiversity. The parasitic mite Varroa destructor in association with viral co-infections plays a key role in this phenomenon; however, the precise mechanisms are still unclear. We employed a unique combination of transcriptomic, proteomic, metabolomic, and functional analyses to elucidate the effects of Varroa parasitisation. We focused on complex differences between parasitised and unparasitised ten-days old honey bee workers collected from identical colonies before overwintering. Honey bees exposed to mite parasitation during their development revealed alterations in transcriptome and proteome related to immunity, oxidative stress, olfactory recognition, metabolism of sphingolipids and RNA regulatory mechanisms. Specifically, immune reactions and sphingolipids metabolism were strongly up-regulated in parasitised honey bees; whereas olfactory recognition and oxidative stress pathways were down-regulated compared to unparasitised bees. Additionally, the metabolomic analysis confirmed the depletion of nutrients, decreased energy stores and generally disrupted metabolism of parasitised workers, as previously reported. By virtue of comprehensive omics-based analysis, we define the key changes in the honey bee facing Varroa parasitism and suggest possible mechanisms underlying its detrimental effects. This study provides a theoretical basis for future efforts in efficient control strategies against Varroa mites.

Nutrigenomics in honey bees: the impact of pollen nutrients on bee health

Project description:We studied the molecular mechanisms underlying the impact of pollen nutrients on honey bee (Apis mellifera) health and how those nutrients improve resistance to parasites. Using digital gene expression, we determined the changes in gene expression induced by pollen intake in worker bees parasitized or not by the mites Varroa destructor, known for suppressing immunity and decreasing lifespan of bees.

Effect of Deformed wing virus (DWV) and Varroa destructor (mite) on gene expression in honeybee (Apis mellifra) pupae

Project description:Experiment was designed to study the effect of Deformed wing virus (DWV) and the mite Varroa destructor on global gene expression using microarray transcriptional profiling in developing worker honeybee (Apis mellifera). Newly hatched bee larvae (day 3 of bee development) were transferred from a Varroa-free colony with low DWV levels to a Varroa-infested colony with high levels of DWV in bees and Varroa mites. All transferred larvae were receiving the DWV strains present in this Varroa-infested colony with the food delivered by the nurse bees until their capping (day 8). About half of these larvae were capped with Varroa mite and were subjected to the mite piercing and feeding on their haemolymph during pupal development until sampling at purple eye stage (day 14). Exposure to the mite piercing and feeding resulted in about 1000-fold increase of the DWV levels in the majority of the mite-exposed pupae compared to the control pupae and the pupae not exposed to Varroa mites.

Effects of Deformed wing virus infection and the mite Varroa destructor on siRNA and miRNA composition in the honeybee (Apis mellifera)

Project description:Experiment was designed to study the effect of Deformed wing virus (DWV) and the mite Varroa destructor on on siRNA and miRNA composition using high-throughput sequencing of small RNA in developing worker honeybee (Apis mellifera). Newly hatched bee larvae (day 3 of bee development) were transferred from a Varroa-free colony with low DWV levels to a Varroa-infested colony with high levels of DWV in bees and Varroa mites. All transferred larvae were receiving the DWV strains present in this Varroa-infested colony with the food delivered by the nurse bees until their capping (day 8). About half of these larvae were capped with Varroa mite and were subjected to the mite piercing and feeding on their haemolymph during pupal development until sampling at purple eye stage (day 14). Exposure to the mite piercing and feeding resulted in about 1000-fold increase of the DWV levels in the majority of the mite-exposed pupae compared to the control pupae and the pupae not exposed to Varroa mites.
