Fight of the Honey Bees



Emerging pathogen responsible for colony collapse

A research team proclaims to have solved honeybee colony collapse disorder within two professional bee yards in Spain. The scientists for the first time isolated a parasite, Nosema ceranae, from infected hives, and then used antibiotics to treat the remaining populations to a successful recovery.

The acute disorder, which causes worker bees to abandon their hive, emerged in bee yards in 2006 in North America and later in Europe. Because bees pollinate important world crops, scientists have scurried to pin down the cause, pointing to everything from viruses and mites to pesticides. The study, in Environmental Microbiology Reports, says it is the first to definitively determine that the Asian parasite – another of the often cited suspects – is the root of the problem under field conditions. The researchers found no evidence of any other potential triggers of collapse. Their finding could help prevent a deepening honey bee population crash, the authors write. – Jessica Leber
