Xyleborus ferrugineus (F) was found damaging stored yam tubers, Dioscorea spp. in Nigeria. Infestation starts in November when the tuber moisture is about 62%. The mean developmental period in the tubers was 32 ± 3 days at 30 ± 2°C. Eggs were laid on the tuber surface damaged during harvesting and the first instar larva burrows inside the yam. Storage of undamaged tubers is suggested to prevent losses due to the pest.
