Robb Cramer, as I've stated several times on this list, has always  
questioned why fumagillan was selected, since in mammals it often affects the  
immune system.  Yet, until something better is found (and he's working on  that 
question), its a trade off btw managing Nosema and the  potential adverse 
affects of use, both to the insect and to the  applicator.  His 
recommendation, follow label directions.    Jerry
