Honeybees dying?

Here's "The Straight Dope" on colony collapse disorder.

First and most important: There are some 20,000 species of bees in the world, and many thousands more types of pollinating insects. What you're hearing about, "colony collapse disorder," affects one species of bee – the European honey bee. That species happens to be the one global agriculture relies upon for about 30% of its pollination requirements. So while we're not talking about losing all the world's pollinators, we are talking about losing a significant fraction of them. That's the worst-case scenario, with the species wiped out completely.

Second, there's no reason at this point to think European honey bees are going to be wiped out, now or ever. The die-offs so far appear to affect some beekeepers more than others, sometimes in the same area....

Third, it's almost impossible to get hard numbers on how many colonies have died recently, and how much of the current uproar is media hype based on guesses, estimates and anecdotal accounts from the handful of beekeepers who have had the most colony losses.

Fourth, even the original report describing and naming the phenomenon explicitly says it's something that has been seen before (repeatedly), named before, and studied before – in all cases without coming to any conclusion about the cause.

Sixth, it's never a good idea to trust what the media are telling you. At least once in the present case the media got something completely wrong and created a huge mess: The story about cell phones was basically a misrepresentation of what one pair of reporters wrote about a study that they misinterpreted. In a nutshell, the original research didn't involve cell phones, and the researchers never said their research was related to honey bee colony die-offs. Even details like the alleged Einstein quote are dubious. No one has yet found proof that Einstein said anything about bees dying off – the earliest documented appearance of the "quote" is 1994 and, yes, Albert was dead at the time.
