A technique was developed to mass rear the greater wax moth, Galleria mellonella, economically (ca. 0.2 cents per larva exclusive of 3-5 h of labor costs per week). Mortality in the egg and early larval stages was ca. 48% whereas in later larval and pupal stages it was ca. 10% and 27% respectively. With a fecundity of 650-1120 eggs per female, and notwithstanding the high egg and early larval mortality, the procedure easily provides a self-sustaining culture with high yields of all stages.
