Life table of forensically important blow fly, Chrysomya rufifacies (Macquart) (Diptera: Calliphoridae)

The life table of the Chrysomya rufifacies (Macquart) (Diptera: Calliphoridae) were studied under the laboratory conditions at 28 ± 2.5ºC and 75 ± 10% relative humidity using field strain from Penang, Malaysia. The raw data collected were analysed based on the age-stage, two-sex life table theory in order to consider both sexes and the variable developmental rate among individuals and between sexes. The population parameters; intrinsic rate of natural increase (r) was 0.2361 d^-1, the finite rate of increase (λ) was 1.2663 d^-1, the net reproduction rate (R₀) was 97.2 and the mean generation time (T) was 19.4. The two-sex life table analysis provides a comprehensive description of the changes in structure stage of C. rufifacies which is potentially useful for forensic investigations in the country.
