Demographic parameters of the Mediterranean fruit fly at various laboratory conditions
TL;DRAbstract
Demographic parameters and their standard errors have been estimated for females of Ceratitis capitata (Wied.) at 31, 28, 25, 22 and 19°C. Highest mortalities were obtained during the larval stage and, generally, the lowest mortalities ocurred at 22°C. Intrinsic rate of increase (r) varied from 0,103 at 19°C to 0,237 at 31°C. The longest mean generation time (T) ranged from 22,97 days at 31°C to 55,57 days at 19°C. The highest net reproductive rate (Ro = 308,72 days) was obtained at 19°C. A new mathematical methodology to estimate demographic parameters and their standard errors is reported.
