As a small beekeeper, having read some on CCD, this article reads like it was authored with someone with an agenda to defend neonicatinoid usage.
I am a hobbyist beekeeper and I agree with you. These companies pay big bucks to have someone produce tests with the results skewed the way they want.
Also there is something else to take into consideration....... companies can show that their individual chemical products do not harm bees, but then we can find that a mixture of two or more of these products makes an entirely different chemical that is harmful.
Something is killing bees and it isn't cell phone towers!!!
