^: The demographics of Bradysia odoriphaga were examined with an age-stage, two-sex life table that was developed at 15, 20, 25, and 30C under controlled conditions. The intrinsic rate of increase and mean generation time were 0.0574 and 48.08 d at 15C, 0.1175 and 30.09 d at 20C, 0.1369 and 26.31 d at 25C, and 0.1247 and 26.55 d at 30C, respectively. The gross reproductive rate (GRR), the net reproductive rate (R0), and the pre-adult survivorship (la) were consistent with the relationship R0&#8201;<&#8201;la&#8201;&#215;&#8201;GRR&#8201;<&#8201;GRR. Development was slower at 15C than at the other temperatures. The mean duration of the total pre-adult stages was 38.01, 27.62, 23.74, and 24.10 d at 15, 20, 25, and 30C, respectively. The highest values for the intrinsic rate of increase, finite rate of increase, and fecundity (0.1369 d&#8722;1, 1.147 d&#8722;1, and 50.53 eggs, respectively) and the shortest mean generation time were at 25C. Still, B. odoriphaga was able to develop, survive, and reproduce across the entire temperature range (15-30C). This study provides insight into the temperature-dependent phenology of B. odoriphaga and will contribute to the modeling of its population dynamics and to its management in the field. aref1
