For the AFB experts out there.
Everyone knows that dark sunken cappings with perforations and chocolate
brown melted-looking larva inside with a bump at the end nearest the
opening (the tongue) means AFB with great certainty, especially if the
gooey mess ropes out when a straw is inserted and pulled back, but by
that point, the disease has been progressing for a while and the bees
have proven unable to keep up with it.
What are signs in the earlier stages, or a case that has not progressed
that far?
For example, do scattered dead pupae lying on their backs in
normal-looking capped cells with tongue extended and no smell
_necessarily_ indicate AFB, or are there many other possibilities for
dead pupae with extended tongues?
