Abstract
The effect of constant temperatures (23º, 27º, and 32±1ºC) on the development and life table of Spodoptera frugiperda that reared on the maize host plant was examined. The developmental times of all stages (eggs to adults) decreased linearly when temperature increased. The incubation period of the egg stage decreased significantly from 4.8 to 1.37 days when the temperature increased from 23° to 32±1°C. Temperature significantly affected on development of immature stages and subsequently the total generation time. The total immature duration lasted 47.07, 27.13, and 14.47 days at 23°, 27° and 32°C respectively. Temperature also significantly affected the life table estimates of S. frugiperda. The highest fecundity (717.67 eggs/♀), hatchability percent (94.29%), and net reproductive rate R0; (85.38 females/female) of S. frugiperda were estimated at 27°C, whereas the highest intrinsic rate of natural increase rm, (1.18 times/female/day) and finite rate of increase erm (1.20 times/female/day) of S. frugiperda were estimated at 32 °C.
