And we can see that the pesticides linger; scientists have found 121 different pesticides in samples of bees, wax, and pollen. “We believe that some subtle interactions between nutrition, pesticide exposure, and other stressors are converging to kill colonies,” said Jeffery Pettis, of ARS’s bee research laboratory.
And why are the pesticides in bees, wax, and pollen? Because two of the best-selling pesticides, Imidacloprid and Clothianidin (by Bayer), are known to get into pollen and nectar. In fact, while these drugs were being marketed in Europe and the US, there were large-scale bee deaths in those places.
Thankfully, after large bee losses were reported- after exposure to Imidacloprid- it was banned for use on corn and sunflowers (as you can imagine Bayer protested this decision). And France rejected Bayer’s application for Clothianidin.
While we are happy for the common sense approach to bee and public health in Europe, it’s time that starts happening here.
