"In my opinion, they are being misleading when they say that the binding is fully reversible. In the lab, yes. In nature??? Not likely, given that the displacement kinetics are completely unnatural. Those metabolites aren't going to be found in a normal synapse, and there isn't anything else except ACh in there to compete with [Imidacloprid]." But the impact must be admitted to be difficult to assess, and hard evidence of tangible effects on colonies has not yet appeared. It could well be that bees just don't live long enough under even ideal conditions to show the effects, and won't show any evidence in anything but one of those "tented colony" studies, where each and every bee that falls can be collected, counted, and post-mortemed. This is essentially the same thing as "no impact", except for the minor detail of how the chemistry actually works at the synapse, something that needs to be better-understood, if not for this pesticide, then for the next one. James! I am surprised, you had to dig deep to find that! With all due respect to Christinas opinion, Lets read her statement. My opinion In a lab yes, Not likely, Difficult to assess It could be And not but not least, something that needs to be better understood..... I am no Scientist, I have never played one on TV, but that statement your using as a club is made out of nothing........ Again, no disrespect to her opinion, its well worthy of consideration, but to base a debate on a 2 year old maybe they lied statement, coming from you, well frankly its one of the oddest things I have read lately.
