Most wild bees are solitary, but one tiny species of carpenter bees fastidiously cares for and raises their offspring, an act that translates into huge benefits to the developing bee's microbiome, development and health, found York University researchers.
of these carpenter bees staves off an overabundance of harmful fungi, bacteria, viruses and parasites in the earliest stage of development.
The biggest single fungus found was Aspergillus, known to induce stonebrood disease in honey bees, which mummifies the offspring. In later stages, the lack of care can lead to a reduced microbiome, increasing susceptibility to diseases and poor overall health. "There are fitness affects resulting from these fungal infections. We are documenting the shifts in development, the shifts in disease loads, and it is a big deal because in
The paper,"The effects of maternal care on the developmental transcriptome and metatranscriptome of a wild bee," is published in the journal. Lead author Katherine Chau of York University is a Mitacs Elevate and Weston Family Foundation Microbiome Initiative postdoctoral fellow.
