Pesticide May Give Honeybee Virus an Advantage - Yahoo! News:
'via Blog this'
A common pesticide used by beekeepers to kill honeybee-infecting mites temporarily leaves the bees more susceptible to a debilitating virus, new research suggests.
From parasitic flies to numerous viruses, honeybee colonies across the globe have a lot of things threatening their survival, but perhaps no stressor is as disastrous as varroa destructor mites. The tiny vampiric arachnids latch onto bees of all stages of life and suck their "blood." Often in the process, the mites deliver to the bees deformed wing virus — which causes wing disfigurements in developing pupae, resulting in flightless bees that die shortly after their emergence. Both these mites and the deformed wing virus have been implicated in colony collapse disorder, and together they can wipe out an entire honeybee colony within a few years if left untreated, scientists have found.
