Some Progress in Disappearing Honeybee Mystery
Scientists trying to crack the Colony Collapse Syndrome (CCD) mystery that's killed millions of beehives worldwide, may be onto something, according to Scientific American: The growing consensus among researchers is that multiple factors such as poor nutrition and exposure to pesticides can interact to weaken colonies and make them susceptible to a virus-mediated collapse. In the case of our experiments in greenhouses, the stress of being confined to a relatively small space could have been enough to make colonies succumb to IAPV and die with CCD-like symptoms. More recent results from long-term monitoring have identified other unexpected factors for increased colony loss, including the fungicide chlorothalonil. Research is now focused on understanding how these factors relate to colony collapse.... More
