Study Credits Family of Viruses in Decline of Honeybee Population

A recent study has reportedly suggested that multiple viruses are responsible for the increase of colony collapse disorder (CCD) among global honeybee populations. Reed M. Johnson, et al., “Changes in transcript abundance relating to colony collapse disorder in honey bees (Apis mellifera),” Proceedings of the National Academy of Sciences, August 2009. According to researchers, “Microarray analysis revealed unusual ribosomal RNA [rRNA] fragments that were conspicuously more abundant in the guts of CCD bees,” which also carried more viruses and other pathogens than their healthy counterparts. The study posits that fragmented rRNA “may be a possible consequence of picorna-like viral infection, including deformed wing virus and Israeli acute paralysis virus.” These viruses are known to “hijack the ribosome” of bees to produce viral proteins instead of the ones needed for survival, explained lead study author May Berenbaum, who noted that the viral overload leaves CCD bees vulnerable to pesticides, disease and other environmental factors.
