<<How many  insects 
sub-lethally affected does it  take to affect a swift lethally  (haven't 
seen 
many of those around  this year).>>



I don't know, but if a predator keeps feeding on  poisoned prey, then the 
poison is going to accumulate in its tissues unless it's  metabolised or 
eliminated fairly quickly. Top predators are particularly  vulnerable; remember 
DDT and peregrines?
