Unhealthy brood

A symptom common to all bee brood diseases is perforated cell caps, or cell caps completely opened or removed.

Some publications describe this as a symptom for AFB, but it is common to all cases of dead brood behind capped cells, even chilled brood that died without a disease.

When the expected hatching of bees from the pupae is overdue the adult bees start opening some of the capped cells to investigate.
