Eggs of artificially reared Dacus oleae (Gmelin) were held for hatching first at 25 for 24 hr, then at various temperatures. Hatch was 80% or more at 10-30, and o at 8 and 35. The incubation period was extended from 2 to 4 days at 30 to 15 to 18 days at 10. Pupae of various ages were held at various temperatures until adults emerged. Emergence was 0 for all tested ages at 5 and 8, below 50% at 11, and below 50% for the younger pupae and above 50% for the older pupae at 14. Maximal extension of the pupal stage was 34.5 days and occurred when very young pupae were stored at 14. At 16, 18, and 20, the pupal stage lasted more than at 25; the duration depended upon temperature and pupal age.
