What's Killing American Honey Bees?

publication Evidence: moderate

Author Information

Author(s): Benjamin P. Oldroyd

Primary Institution: University of Sydney

Hypothesis

What is causing the mysterious disappearance of honey bee colonies, known as colony collapse disorder (CCD)?

Conclusion

Colony collapse disorder is a multifactorial syndrome with no single cause identified, but various factors such as diseases, pesticides, and environmental stressors may contribute.

Supporting Evidence

  • Beekeepers in 22 states reported unusually high rates of colony loss in early 2007.
  • Colony collapse disorder (CCD) is characterized by a low number of adult bees in the hive without any signs of disease.
  • Some beekeepers experienced 80-100% losses in their colonies in 2007.

Takeaway

Many honey bees are disappearing, and scientists are trying to figure out why. It could be due to sickness, chemicals, or not enough food.

Limitations

The study does not provide a definitive cause for CCD and acknowledges the complexity of the issue.
