Maybe it is not the fact that the chemicals are present but the combined
effect of these chemicals on the bees. As I recall (taking Bill's advice)
from talks and reading, if there are a couple of chemicals present it is not
just an accumulative effect. Say A is 1X lethal to bees and B is 2X lethal
to bees. If you have A + B it is not 3X but can be say 6X. So if there
were 5 pesticides present imagine what the cumulative effect could be if the
effect is not just a matter of adding up the effects but a greater factor.
