Abstract
The life history of the oriental latrine fly,
Chrysomya megacephala (Fabricius), was studied at 26 °C in the laboratory. The raw data were analyzed based on the age–stage, two-sex life table, in order to take both sexes and the variable developmental rate among individuals and between sexes into consideration. The intrinsic rate of increase (
r), the finite rate of increase (
λ), the net reproduction rate (
R
0) and the mean generation time (
T) of
C.
megacephala were 0.2182, 1.2438 d
–1, 91.7 offspring/individual and 20.7 days, respectively. The life expectancy of a newborn egg is 32 days. The maximum reproductive value of females is on the 19th day, which coincides with the total pre-oviposition period counted from birth. The two-sex life table analysis gives a comprehensive description of the stage differentiation of
C.
megacephala.
