Colonies can normally handle chalk brood (resembling corn kernals)
before those mummies have formed. In my studies of varroa infested
colonies, I have found that colonies under stress from varroa no longer
seem able to cope. the result has been a severe eruption of chalk brood.
In an advanced stage, half of the brood can be chalk brood and the other
half quite neglected larvae.
