>And the point that the authors make is that direct exposure of larvae to an insecticide would be only through the small amount of pollen that is fed to them directly.  With Megabee patties in my experiment, this appeared to be close to zero.

BTW, do you know what, if any, neonics are in the MegaBee and a what concentrations, if any? Apparently neonics can be found in some plant products and are therefore  permissible levels established.  Further, it is my understanding that some of those permissible maximums are high enough that a product approaching those levels could contain more neonics than you plan to administer.  

What do we know about detection of all the various neonics and their various metabolites?  Can we be confident that they are all detected and measured?  Is it more expensive to test for and measure all, rather than just some?
