In this study a simulation model of the population dynamics of Culex tritaeniorhynchus (TriDyn) was developed using the dynamic life table approach. The model took account of the density dependent effects on larval mortalities. A density independent factor reflecting the seasonal variation of survival rates of immatures and females as well as fecundity of females is described using a sinusoid function. The simulation demonstrated the significant role of the density dependent effect in the dynamics of Culex tritaeniorhynchus populations, suggesting that the bimodal and fluctuating population dynamics observed in light trap samples in Shanghai may have resulted from an overcompensation of density dependent processes.
