Some other hypotheses being considered (not by the working group, but others) are – overuse of pesticides, artificial insemination of queen bees, and increased solar radiation because of the ozone layer depletion.
Excuse me? As far as I know, CCD has not yet been reported in Asian countries (only in North America and Europe).
Doesn’t the USA ban agriculture imports from India because of “too many pesticides”? Artificial insemination is not yet widespread in India. And isn’t solar radiation higher in the tropics?
Nah. Forget the fairy tales. The Working Group is considering only parasite/pathogen, chemical contamination, nutritional fitness, stress-inducing proteins, and lack of genetic diversity in the lineage of bees as possible causes.
