Figure 1. Old comb with AFB “scale” hardened and stuck to lower edge of comb. Comb is upside down in photo to expose lower part of cells.
Figure 2. AFB kills sealed brood. Symptoms include brood cells with perforated cappings and brown, gooey, smelly dead brood inside.
Figure 3. The “ropiness” test to determine if brood has AFB
Figure 4. An EFB infection kills larvae before they are sealed. The dead larvae do not become ropy.
Figure 5. Chalkbrood kills sealed brood. Symptoms include brood cells with perforated or opened capping with hard white or black “mummies” inside.
