All 3 are ccd, N yard

A revist to #3, no chewed comb found, not ccd
Probably less mites in S yard

Mites are the cause of the resurgence, 75%? 
MORE formic next yr!!
All 6 probably 2 yr Q with lifelong exposure to ccd
But I don't know whether to blame the Q for the dead brood

So these 3:
2 from 5 nuc group
2 were russian cross

3-400 cells dead, 2-300 cells chewed
(#1 & #2 had chewed cells too)

Differences
#4 Less brood, 3x normal on BB, 
small pile off end of BB

#5 Younger brood, some dead on porch

#6 Older brood, emergents, Cleanest BB
Next to #1


Brood mortality pattern

5-8% emergents
60-70% coloured
20-30% just sealed or +1d, few cucoons
5% 3.5-4d larv, no wiggle
1-2% yuk, various fungi, bacterial
very few translucent, purple eye (eaten?)

not all in same hive!!

In chewed comb the remains seem to be 80% coloured
Eating these corpses is likely most unhealthy
To bad they don't remove them intact
I do know that they dislike this particular job,
probably the smell?
In any case, a potent vector for reinfection
Maybe the trigger for exodus/abscond

I could use a little help
Vectors?  Disinfection?  Heat? Ozone? UV? Lysol? Bleach?
