I don't know how much lag time there is with Bee Culture articles but this is much up to date:

> Overall, elevated expression of pesticide response genes was not observed. 

> Genes involved in immune response showed no clear trend in expression pattern despite the increased prevalence of viruses and other pathogens in CCD colonies. 

> Microarray analysis revealed unusual ribosomal RNA fragments that were conspicuously more abundant in the guts of CCD bees. 

> The presence of these fragments may be a possible consequence of picorna-like viral infection, including deformed wing virus and Israeli acute paralysis virus. 

> Ribosomal fragment abundance and presence of multiple viruses may prove to be useful diagnostic markers for colonies afflicted with CCD.

[It is no coincidence that viruses are huge right now, but I don't think it has to do with management or lifestyle issues]
