Different plant species may indeed move the neonic differently.  As to the 
volume of pesticide, the total volume( lbs/acre) is likely similar.  The 
canola seed is smaller, but the number planted is much greater for canola. 
Corn pollen, and sunflower pollen are low in protein and not a complete 
amino acid compliment.  In the rush to blame neonics are we forgetting 
nutrition, and the defecits brought on with moncultures.
