RNA Viruses in Hymenopteran Pollinators: Evidence of Inter-Taxa Virus Transmission via Pollen and Potential Impact on Non-Apis Hymenopteran Species
For the first time, molecular detection of picorna-like RNA viruses (deformed wing virus, sacbrood virus and black queen cell virus) in pollen pellets collected directly from forager bees are reported, indicating that pollen itself may harbor viruses.
Genetic and genomic analyses of the division of labour in insect societies
Different forms of division of labour, in lineages in which eusociality has arisen independently, have evolved through changes in the regulation of highly conserved molecular pathways associated with several basic life-history traits, including nutrition, metabolism and reproduction.
Worker nutrition and division of labour in honeybees
Insights into social insects from the genome of the honeybee Apis mellifera
The genome sequence of the honeybee Apis mellifera is reported, suggesting a novel African origin for the species A. melliferA and insights into whether Africanized bees spread throughout the New World via hybridization or displacement.
Wasp Gene Expression Supports an Evolutionary Link Between Maternal Behavior and Eusociality
Wasp brain gene expression in workers was more similar to that in foundresses, which show maternal care, than to thatIn queens and gynes, which do not, suggesting that the evolution of eusociality involved major nutritional and reproductive pathways.

The results indicate that although social interactions affect the nutritional status of young bees, social and nutritional factors act independently to influence age at onset of foraging, and suggest that mechanisms linking internal nutritional physiology to foraging in solitary insects have been co-opted to regulate altruistic foraged in a social context.

Carbohydrate metabolism genes and pathways in insects: insights from the honey bee genome
Striking changes in gene number or genomic organization are identified for genes encoding glycolytic enzymes, cellulase, glucose oxidase and glucose dehydrogenases, glucose‐methanol‐choline (GMC) oxidoreductases, fucosyltransferases, and lysozymes in the honey bee and mosquito.

A significant overlap of genes associated with foraging/provisioning, but not reproduction, across the two species is found, suggesting common molecular roots for foraging division of labour in two independently evolved social insect species and the possibility of more lineage-specific roots of reproductive behaviour.
Comparative transcriptomics of convergent evolution: different genes but conserved pathways underlie caste phenotypes across lineages of eusocial insects.
Overall, the first comparative transcriptome-wide analysis of caste determination among three major hymenopteran social lineages found few shared caste differentially expressed transcripts across the threeSocial lineages, but there is substantially more overlap at the levels of pathways and biological functions.
