back to the topic of sublethal 

in the latest ABJ  Nov 2008 issue in Jerry Hayes Classroom Column

Jerry comments about the use of Imid to fight insects on shade trees and says 

" I was just at a meeting today that shows the Imidacloprid in as little as 5ppb can result in as much 
as 70% bee mortality in developing pupae when the larval food includes Imidacloprid." 


Must be some new research in the pipeline - should be interesting.....
