Life Table of Blue Bottle Fly Lucilia cuprina (Wiedemann, 1830)

摘要

The life history of the L. cuprina was studied at 25±2°C in the laboratory conditions on lamb meat as host. Egg we counted by daily meat replace, and kept obtained duration to complete life cycle. Time period from egg to adult were analyzed based on the age–stage, two-sex life table by computer program. The obtained life history parameters of L. cuprina were as follows: the intrinsic rate of increase (r)= 0.231, the finite rate of increase (λ)= 1.260 day-1, the net reproduction rate (Rо) = 109.62 offspring per individual; and the mean generation time (T) =20.35 days. The maximum reproductive value of L. cuprina females was on the 14th day. The two-sex life table analysis showed a comprehensive description of the stage differentiation (age-stage specific survival rate, life expectancy of each age–stage, and reproductive value of each age–stage). This experiment has a significant impact on stage-specific control strategies and postmortem interval estimation.
