Several good discussions on Neonics and bees lately.,  one thing keeps bothering me.  we discuss and debate about uptake levels and dosages,  it seems to me these are simple test?  if we can measure levels in wax, and soil with such pinpoint accuracy,  we can we not crush up a few larva from healthy and sick hives and see what levels they are really getting fed?    from the outside looking in the only thing I can think of is is that its been done,  but did't give teh results that sell??  what am I missing here?
