European honeybees are being poisoned with up to 57 different pesticides, according to new research published in the Journal of Chromatography A. A new method for detecting a whole range of pesticides in bees could help unravel the mystery behind the widespread decline of honeybees in recent years, and help develop an approach to saving them.

Honeybees are under threat globally: in the US, dramatic declines in bee populations due to a condition called colony collapse disorder (CCD) continues to put crops at risk an farmers out of business. Several studies have shown a link between pesticide use and bee deaths and the European Union has banned the use of neonicotinoid pesticides.

But it's not as simple as banning one pesticide that's killing bees; the relationship between pesticide use and bee death is complex and scientists are still trying to figure out exactly what's happening. In the new study, researchers from the National Veterinary Research Institute in Poland have developed a method for analyzing 200 pesticides at the same time, to figure out what's really putting honeybees at risk.
