The life cycle of Ephestia cautella (Walker) on ground corn ranged from 25-45 days with an average of 41 days. The mean duration of the different stages were: egg-three days, larva-twenty-three days, pupa-six days, and adult-nine days. The larva has five to six instars and the mean duration of each was: four days (first), four days (second), three days (third), four days (fourth), two days (fifth), and six days (sixth). Oviposition period was four days. Based on duration of development period and growth index, peanut, cacao seed, sorghum, and yellow corn were most suitable for the development of the insect while mungo, okra seeds, and cassava flour were poor hosts. It could also infest cowpea, rice, flour, wheat0865 and pole be
