It would appear that the Telegraph is playing down its own story on the part that mobile 'phone signals may play in the collapse of bee colonies. As mentioned in the Colony Collapse Disorder wiki, I linked to previously, as well as elsewhere on the Green Mole Forum (including our Look Local article), current possible causes include pesticides, Varroa mites, changing climate, new predators (such as the Asian hornet now in France) and interference from transmissions (studies have been inconclusive), or quite likely a combination of these factors. Thanks go to our resident permaculturist, and Transition Bookham Food Group champion, Esther, for pointing this out.
