Similar symptoms do not necessarily
mean a similar  cause.
Beekeepers at that time (70's) were 
claiming losses of 40%  starting in 1974, 
and Idaho massive bee kills in 1976.
Researchers  state:
"We concluded that Penncap M 
was probably the cause."

I saw the Penncap M losses - they were not what Wilson called  Disappearing 
Disease, not what is called CCD.  With Penncap M, you get  dead bees.
 
 
 
Wilson and colleagues did some low dose pesticide trials over winter,  and 
they got a Dwindle, but he and his colleagues found what you'd expect if you 
 fed bees pesticides.
 
 
There's a very good reason why some researchers disagreed with Bill at the  
time.   Someone (Randy?( should get the full story from  Bill.
 
 
 
There's a difference btw dwindle (slow attrition) and disappear  (bees 
suddenly vanish).
 
Also, similar signs don't necessarily mean similar cause, but then  again, 
similar symptoms (signs) don't rule out similar cause.
 
Personally, I don't put much faith in the Different Causes can  each 
produce such a distinctive set of signs.  Might be true, or may  simply be because 
cause hasn't been verified.  If we were talking about a  dwindle, I'd 
agree, lots of things can set a colony off on a downward  spiral.  Colonies 
suddenly collapsing, young bees and  queen remain,  often lots of brood and food, 
no dead bodies to find, that's rather  specific.
