The present paper investigates the pupal development times ofLucilia sericata which were studied in the laboratory at six different constant temperatures (20, 22, 24, 26, 28 ℃ each ± ℃). Lower thresholds (tL) for development were estimated from the linear regression of the developmental rates on each temperature. These data have made it possible to calculate the ADD (Accumulated Degree-Days) necessary for L. sericata to complete the larval stage and to achieve adult emergence. The minimal duration of development from oviposition to adult emergence was found to be inversely related to temperature. Additionally, six landmarks in pupal development are showed and for each of the landmarks the ADD value was calculated for every rearing temperature involved. These data assist in calculating the duration of the pupal stage based on morphological characteristics and would be of great value for future forensic entomological casework. 展开更多
