PARASITE TIED TO GLOBAL BEE DEATHS

[Another man-is-the-problem disinformation campaign bites the dust.]

The sudden collapse of honeybee colonies around the world, a condition identified in 2004, is most likely caused by the parasite Nosema ceranae, not the human causes alleged by environmental activist groups.

Spanish researchers have reported in Environmental Microbiology Reports, a journal of the Society for Applied Microbiology, finding Nosema ceranae as the only common thread among them:

  • Since 2004, honeybee populations around the world have been succumbing to Colony Collapse Disorder, characterized by worker bees leaving their hives and dying off without returning.
  • Loss rates have varied from 30 percent to 90 percent of regional colonies.
  • With no known cause to account for the die-offs, environmental activists blamed everything from pesticides [man] to cell phones [man] to global warming [man].
In April, Dr. Mariano Higes, lead researcher at the Bee Pathology Laboratory in Spain, announced scientists had found the likely cause. The parasite Nosema ceranae was found in all the bee populations they studied.

Once that was discovered, the Spanish science team introduced fumagillin -- an antibiotic -- into the affected bee colonies. It cleared the parasite and halted colony collapse. Many colonies began to rebuild their numbers shortly thereafter.

This is the same thing that happened with frogs when amphibians were declining, says H. Sterling Burnett, a senior fellow at the National Center for Policy Analysis. The environmental activists were quick to point their finger at global warming, pesticides and other human activities, when it turned out entirely natural factors were the cause.

Of course, after the activists' media allies sounded the alarm that pesticides and global warming are killing frogs and bees, they became strangely silent about reporting the exculpatory evidence that natural factors are to blame,.

"The general public has no idea that humans in fact were not to blame, unless they subscribe to and read academic journals."
