Colour of Brood
Infected larvae
Infected prepupae
Larvae infected with AFB are only ever found stretched out along the lower wall of the cell (prepupal stage). Infected larvae are never found in the c-shape of younger larvae, since the disease-causing bacteria do not penetrate the gut wall until just before the larvae pupate.
Prepupae infected with AFB are always found in the characteristic prepupal position, stretched out along the lower wall of the cell, with the head closest to the cell entrance (Fig. 20).
Diseased prepupae and pupae are always stretched along the lower wall of its cell.
