lots,

a.- Not sure after all the calculations done before, but, does oxalic
dehidrate contain 71.4% of oxalic acid?
b.- 1:1 sugar:water is not 50%,  is 61.7% and 60.2% when 70 gr of oxalic is
add.
c.- to high temperature and too low RH% for any treatment.
d.- adult bees start to die at a higher rate 12 days after second treatment,
therefore it is difficult to believe that it is caused by the oxalic
treatment, particularly when there is no higher mortality after same period
with first treatment. More interesting is that the rithm of control and
treated colonies (fig 3) is quite similar over time what shows a different
cause as the bee killer (virus?, nosema? agrochemical?)

e.- too low "natural drop" on control colonies for hives with no treatment
after one year.

f.- it is not stated the date when coumaphos was applied.
